[Abstract](1231) [PDF 856KB](600)
Abstract:
The plant coenology survey has done in northeast-southwest grassland transect in Inner Mongolia by using method of transect-sample area-quadrat. Then based on the results of both indoor and outdoor investments and measures, the gradient changes of aboveground biomass were analyzed. The main conclusions are as follows: (1) the background biomass along the northeast-southwest transects in Inner Mongolia ranges from 50-80 gm-2; the value of grassland's aboveground biomass reduced with the change of vegetation type. It shifts from meadow steppe to typical steppe and desert steppe. (2) the total aboveground biomass of grassland has no strict corresponding relation with the land use intensity because of the impacts of human activities such as farming, field's abandoned and returning reclaimed land and forests and so on. But the biomass value of essbar perennation plant is declining with the intensity of land use. (3) using aboveground biomass to evaluate the quality and health of the ecosystem was partly limited. The percentage of biomass value in different land use intensity quadrat and background quadrat could hit the aim of rejecting the impacts of natural geographical area, regional climate background, and could analysis the influence of economic performance and economic structure development on the grassland ecosystem.

[Abstract](1279) [PDF 491KB](492)
Abstract:
The effects of the enclosure on the resource allocation pattern and ecological strategy of Seriphidium transiliense population was investigated. The content, storage and allocation pattern of biomass, carbon and nutrient elements in the sagebrush desert grassland were analyzed on September and October, 2009 and 2010. The results showed that the P content of root, the N content of reproductive shoot, the Ca content of root crown and vegetative shoot in enclosure of moderate degraded plot were significantly higher than those of outside plots (P0.05). The storage of N, P, K significantly increased after enclosure (P0.05). The storage of C, the biomass of reproductive shoot and vegetative shoot increased with the decreasing of degraded intensity, and the values increased more in enclosure of moderate degraded plot. The proportion of N, K of reproductive shoot, the proportion of Ca, Mg and C of vegetative shoot, the ratios of N and C of root crown all showed an increasing trend after enclosure. The ratios of N and C of reproductive shoot in enclosure of moderate degraded plot were significantly higher than those of outside plots (P0.05). The present results suggested that the supply capacity of nutrition of the soil, the resource allocation to vegetative shoot and reproductive shoot all increased in the sagebrush desert grassland after enclosure. The improvement of soil and these performances of S.transiliense population were beneficial to its ecological restoration.

2012, 6(10): 1512-1516.
[Abstract](1147) [PDF 487KB](528)
Abstract:
This study substituting a space series method for a time course method, was conducted in a degraded desert steppe in Yanchi. The changes of plant community composition and species diversity of desert steppe among different years of enclosure and the unenclosed grassland were investigated. The results showed that the community composition and species diversity had varied after enclosure, meanwhile, Ephemerereum and semishrubs gradually replaced by perennial herbs. With increased periods of enclosure, species diversity indicator reached a minimum at the 5th year then gradually increased.
Influence of restoration measures on plant community in alpine meadow
2012, 6(10): 1517-1520.
[Abstract](1443) [PDF 605KB](581)
Abstract:
To investigate the influence of different restoration measures on plant communities, fertilization, overseeding, sward ripping and comprehensive treatment were applied in alpine meadow ecosystem. The results showed that the four treatment measures had different effects on plant functional group, plant community structure, species diversity, and productivity of grassland. Different measures had no significant effects on plant functional group composition, but had different influence on species number within functional group. Compared with community coverage (P0.05), the community height showed significant variation (P0.05) under four treatments. Four treatment measures significantly improved aboveground productivity but had different effects on plant species number and Simpson index. As for species numbers, only reseeding and comprehensive treatment had significant difference compared with controls (P0.05). While for Simpson index, besides comprehensive treatment, the other three treatments all had significant difference compared with controls (P0.05). Our research suggests that although restoration measures used in our experiment had different effects on species composition, community structure, and species diversity, they obviously promoted grassland productivity. These measures, therefore, can be considered as profitable restoration practices in management of degraded grassland.

Overall, enclosure+irrigation measures are the best improved measures in the degenerated alpine grassland of Gaize county, Tibet.
Typical grassland classification and precision evaluation based on remote sensing data in the northern slope of Tianshan Mountain
2012, 6(10): 1526-1532.
[Abstract](1190) [PDF 826KB](513)
Abstract:
Vegetation classification based on remote sensing data can quickly get vegetation change information at large scale. This paper chose the Landsat TM data in 2008 and Landsat ETM+ Pan data in 1999 of the typical grassland in the northern slope of Tianshan Mountain. The data used in this paper were preprocessed firstly, then the two temporal remote sensing data were fused by means of remote sensing and GIS (Geographic Information System) technologies. The vegetation in the study area was classified into eight types by visual interpretation based on the texture feature of the fused remote sensing image. Besides, we established an expert knowledge decision tree system to make a further classification combining the preliminary classification results of the visual interpretation. At last the grasslands in the study area were classified into five types, including plain desert, desert plants, lowmountain desert, temperate meadow and alpine meadow. The results of accuracy evaluation indicated that the overall classification accuracy reaches to 95%, and the overall Kappa coefficient is 0.9396, which suggests that the vegetation classification methods based on the fused image generated by nineyear interval TM and ETM+ Pan images and decision tree classification in the study area have higher feasibility. The classification effect is good and consistent with the actual vegetation cover situation.

2012, 6(10): 1533-1538.
[Abstract](1094) [PDF 497KB](507)
Abstract:
Based on Landsat TM image data in 1980, 1994 and 2008, the 3S technology was used to map the land use types and determine the features of land use/land cover change of the Barkol Kazakhstan autonomous county in Xinjiang Province. This study showed that the of construction land, arable land and forest land areas increased and water area decreased in the Barkol Kazakhstan autonomous county during last 28 years; the grassland area firstly decreased from 1980 to 1994 and increased from 1994 to 2008, finally its area increased, and the unused land showed a opposite trend to grassland area. The comprehensively dynamic degree of land use during 1994-2008 was bigger than that during 1980-1994, implying that the transferable rate of land use types increased gradually. This study also proposed that the global warming and ecological engineering were the main drivers of land use/land cover change.

[Abstract](1329) [PDF 696KB](569)
Abstract:
The chromosome numbers and karyotypes of four varieties (lines) of Vicia were studied by the root tip cells. The results indicated that the chromosome numbers of all four varieties (lines) were the same, 2n=2x=12. The karyotype formulas of V.sativa Lanjian No. 3 and V.angustifolia 333/A were 2n=2x=8m+2sm+2st and 2n=2x=2m+8sm (2 SAT)+2st, respectively, while V. sativa 2556 and V.sativa 2560 were the same with 2n=2x=10m+2sm . The karyotype of Lanjian No.3 and 2556 were 2B types, while 2560 with 1B type and 333/A with 3B type. These results demonstrated that some genetic differentiations were existed among different varieties (lines) of V.sativa.
Characteristics of pyrroline5carboxylate synthetase genes and the enzyme activity in three Festuca arundinacea from Guizhou Province
2012, 6(10): 1546-1552.
[Abstract](1802) [PDF 643KB](726)
Abstract:
Pyrroline5carboxylate synthetase (P5CS) is the key enzyme in the proline synthesis from glutamate. As the main osmoregulation substance in plants, proline accumulation is positively correlated with the adaptability of plants to drought stress. Samples were chosen from three tall fescue (Festuca arundinacea) plants, Qiancao No.1 (QC1), Qiancao No.2 with narrow leaf (QC2n) and broad leaf (QC2b). The upstream and downstream of P5CS genes from three samples were cloned by reverse transcription polymerase chain reaction (RTPCR) method. The complete P5CS genes of QC1, QC2n and QC2b were spliced with open reading frame of 2 151 bp in length and encoded P5CS protein consisted of 717 amino acid residues. Compare to the known genes deposited in GenBank, the highest homology of P5CS genes from QC1, QC2n and QC2b with Puccinellia chinampoensis is 94%. Furthermore, six different amino acids were found from the Glu5kinase domain of the encoded P5CS protein among QC1, QC2n and QC2b samples, in which amino acids at site 37, 85 and 142 were changed from hydrophobic residues into positively charged hydrophilic ones. The enzyme activities of P5CS and the proline content of leaves in sample QC1 were the highest and those of QC2b were the lowest. The results suggested that the amino acids changes in the Glu5kinase domain of P5CS might be pivotal for the enzyme activity, proline biosynthesis and the drought tolerance of F. arundinacea.

2012, 6(10): 1563-1568.
[Abstract](1117) [PDF 398KB](441)
Abstract:
The effects of planting density and nitrogen application on the forage yield, yield component traits of Zea maysZ.mexicana hybrid were studied using a split plot experiment with two factors. The results showed that there were significant responses of yield and yield component traits of Z.maysZ.mexicana hybrid to planting density and nitrogen application, and the forage yield had changed with planting density and nitrogen application enrichment. The forage yield was negatively associated with green leaves, leaf length and leaf area, positively associated with density, nitrogen application, main stem perimeter, tillers, leaf broad and single plant fresh yield and very significantly positively associated with grass length. The single plant fresh yield was highly significantly associated with planting density, grass length, main stem perimeter, tillers and leaf broad and leaf area. Meanwhile, the direct actions of planting density (P0.05), single plant fresh yield (P0.05), grass length (P0.05) on forage fresh yield were significant at levels of 0.05, 0.01, 0.1, respectively. These results suggested that the planting density, single plant fresh yield and grass length were important characters for improving forage yield. The fresh forage yield of Z.maysZ.mexicana reached the highest at 59 444.74 kgha-1 with the planting density and nitrogen application of 40 000 plantha-1 and 450 kgha-1, respectively; meanwhile, the maximum dry forage yield reached the highest at 12 374.39 kgha-1 when the planting density and nitrogen application of 40 000 plantha-1 and 600 kgha-1, respectively. In conclusion, planting at 40 000 plants per hectare and applying 450 kg nitrogen per hectare were best management practices.

2012, 6(10): 1569-1573.
[Abstract](1299) [PDF 354KB](481)
Abstract:
Coldresistance breeding for Oenothera speciosa in Beijing was carried out. Many times of bulk selection breeding, conventional cross breeding, radioactive breeding and ion implantation breeding were used in this study. Results showed that many times of bulk selection breeding could enhance cold resistance of O. speciosa which made the surviving rate of overwintering raised from 4.7% to 6.5% in four years. Cross breeding was performed with O.speciosa and another two coldresistance species, but there were no hybrid seeds during many years study. With the treatment of radiation dosage 200 Gy and 60Coradioactive to big seeds, the surviving rate of the seeds was 44.4%, while the surviving rate of overwintering could achieve 37.5%. The surviving rate of O.speciosa was 73.1% with the treatment of energy 35 MeV, injection dosage of 51010 Pcm-2, and Si ion implantation to small seeds, and the surviving rate of overwintering could achieve 55.3%. Notably, Surviving rate of overwintering was 6.5% before treatment. The best method to enhance cold resistance of O.speciosa is Si ion implantation, which made the highest surviving rate of overwintering in this study.
Effects of nitrogen form on seedling growth and its photosynthetic characteristics of forage mulberry
2012, 6(10): 1574-1580.
[Abstract](1574) [PDF 468KB](677)
Abstract:
A hydroponic experiment was carried out to determine the effects of different proportions of nitrate and ammonium nitrogen on seedling growth and its photosynthetic characteristics of mulberry (Morus alba) variety Qinglong under the same nitrogen amount. This study indicated that the combination of nitrate and ammonium nitrogen increased the plant height, leaf number, leaf area, root length, and leaf and root biomass of mulberry seedlings when compared to application of single ammonium or nitrate nitrogen. The plant growth and biomass of mulberry seedlings were the highest when the proportions of nitrate and ammonium nitrogen were 50∶50 and 25∶75. The net photosynthetic rate (Pn), stomatal conductance (Gs) and water use efficiency (WUE) in leaves of mulberry seedlings growing in 25∶75 proportion solution of ammonium and nitrate nitrogen were higher than those of other proportion solutions. Single ammonium or nitrate nitrogen greatly improved the apparent quantum yield (AQY) and decreased the light compensation point (LCP) in leaves of mulberry seedlings. This study suggested that forage mulberry varieties Qinglong preferred to nitrate nitrogen, and the optimal proportions of nitrate and ammonium nitrogen for mulberry seedling were between 50∶50 and 25∶75.
Analysis on types and diversity of desert plant communities in Kumutage Desert
2012, 6(10): 1581-1588.
[Abstract](1206) [PDF 455KB](503)
Abstract:
The line investigation method was used to study types and species diversities of desert plant communities in Kumutage Desert. The results indicated that there were three vegetation types in Kumutage desert, which were 1) the Gobi desert vegetation, including 17 desert plant communities distributed in front of the mountain in the south fringe of Kumutage Desert; 2) the desert meadow vegetation, including 12 desert plant communities in the east and north fringe of Kumutage Desert; and 3) the sandy desert vegetation, including 13 desert plant communities.Species diversities of desert plant communities in different areas were varied due to the difference of their distribution areas. However, Gobi desert vegetation in the south fringe was steady with higher species diversity index (1.437) and homogeneity index (0.824), but the dominance index was lower (0.302). There were less species composition and poor community stability of sandy desert vegetation, which the average indices of diversity and homogeneity were 0.725 and 0.533. Species diversity of the desert meadow vegetation in the east and north fringe was not very high and community relatively steady, which the average indices of diversity, evenness and dominance were 0.804, 0.807 and 0.547, respectively. With the drought intensification of climate and environment, the species diversity of Gobi desert vegetation tended to reduce, but the species diversity of desert meadow vegetation in the north fringe was significant higher than the central location caused by the different soil structure and composition. However, the factors, such as regional landform, geomorphy and hydrology, closely related to the diversity difference of desert plant communities of the two longitude lines.
Responses of biomass, nutrient allocation of Leymus chinensis along N, P and water gradients
2012, 6(10): 1589-1595.
[Abstract](1153) [PDF 467KB](589)
Abstract:
Three pot experiments, which included two fertilization experiments (N or P fertilizer) with 10 levels of 0,0.5,1,2,4,8,16,32,64,128 gm-2 and a water supply experiment at 11.5,12.7,14.3,16.4,19.1,22.9,28.7,38.2,57.3,114.6 mLcm-2, were conducted to evaluate effects of N or P fertilizer and watering on biomass and nutrient allocation of Leymus chinensis in this study. The results showed that with increase of N and P application, biomass and nutrient contents of both aboveground and underground of L.chinensis tended to increase firstly and then decrease, while rootshoot ratios showed decreasing trends. The responses of biomass and nutrient contents of both aboveground and underground to water gradients were similar as those to the nutrient gradients, but the rootshoot ratios did not show significant change in the water supply experiment. The biomass and nutrient contents of aboveground were higher than those of underground during growth season (in August), whereas there was a contrary trend at the end of growth season (in October). These results indicate that changes in N, P and water availabilities in soil could affect the accumulation of biomass and nutrients both in aboveground and underground of L.chinensis substantially; more biomass and nutrients were allocated to abovegroud in August and then transferred to underground at the end of growth season. Therefore, global climate change changed growth and nutrient use of plant, which will further influence structure and function of the plantsoil system in Inner Mongolia temperate steppes.

HKT transporters and their involvement in plant salt tolerance
2012, 6(10): 1604-1612.
[Abstract](1662) [PDF 760KB](541)
Abstract:
Salinity stress is one of the major factors influencing plant growth, during the longterm natural selection. Plants have formed various mechanisms to cope with salinity stress. Highaffinity K+ transporters (HKT) wildly exist in plants. They might make a significant contribution to Na+ recycle in higher plants and play an important role in maintaining lower Na+ concentration, higher K+/Na+ ratio in higher plant, especially in leaves. Subjects regarding molecular feature, structure and function of HKT transporter, and its relationship with plant salt tolerance are summarized in this review.
Advance in Dasypyrum villosum a valuable wild species used in wheat improvement
2012, 6(10): 1613-1621.
[Abstract](1071) [PDF 544KB](605)
Abstract:
It is one of the most important and effective ways for wheat improvement to transfer the useful gene of the relative genus of Triticum into wheat. Dasypyrum villosum is a valuable wild species commonly used in wheat improvement. The article is an attempt to summarize available information about karyotype and chromosome banding pattern in D.villosum, the relationships between D.villosum and T.aestivum, hybridization of D.villosum and T.aestivum, and potentially useful traits of D.villosum used in wheat improvement. D.villosum possesses many important agronomic traits, such as resistance to many main wheat diseases, winter hardiness, vigorous tilling ability, multispikelets, high grain protein content and salt and drought tolerance. Therefore, it is a valuable wild gene resource for wheat improvement. Until now, a great achievement has been made in transferring beneficial genes of D.villosum into wheat through developing addition line, substitution line and translocation line of D.villosum to wheat. The investigations using molecular RAPD, AFLP, SSR, RFLP, STS markers and GISH (genome in situ hybridization) on D.villosum itself and hybridization with Triticum are summarized. Chromosomal localization of the potentially useful traits and chromosomal position of some morphological and isozyme markers of D.villosum are shown. This information will be benefit for farther exploitation and utilization of D.villosum in wheat improvement

2012, 6(10): 1622-1626.
[Abstract](940) [PDF 390KB](473)
Abstract:
Studying the relationship between occurrence regularity of various stages of the meadow moth (Loxostege sticticalis) and meteorological factors is a good way to prevent the meadow moth effectively and alleviate possible disaster losses. Based on the correlation analysis between spawning and hatching time of overwintering generation of adults, development times of 1 to 3age larvae, the duration from the first day of peak catch to 3age larvae and meteorological factors and comparison analysis of these factors at typical years, we developed a forecast model on the duration from the first day of peak catch to 3age larvae by using multiple linear regression of optimal subset. According to the duration from the first day of peak catch to 3age larvae, the study determined the optimal controlling period of first generation larvae of the meadow moth. Average errors between simulated and observed values were about 1.2 days. These results are of importance to direct farmers to prevent the meadow moth, improve control effect and alleviate losses as much as possible.

Influence of main factors on grass litter decomposition
2012, 6(10): 1631-1367.
[Abstract](1245) [PDF 477KB](703)
Abstract:
Litter decomposition is ecosystem material circulation and the main part of energy flow. The protection of soil and water has an irreplaceable role of litter decomposition. This paper analyzes the impacts of nonbiological factors (precipitation, temperature), biological factors (animals, microbes, species) and objective factors on grass litter decomposition. The results showed that these factors could affect litter decomposition process directly and indirectly. The direct effects mainly changed the litter size and vegetation composition, thus changed the decomposition rate eventually. On the other hand, the indirect effects included changing the litter substrate C/N ratio and contents of litter lignin and nitrogen.
Analysis of factors affecting oasis agricultural development and countermeasure in Zhangye
2012, 6(10): 1638-1641.
[Abstract](1091) [PDF 382KB](503)
Abstract:
Agriculture is the leading industry in Zhangye, which plays an important role in oasis economic development. Recently, the population growth, irrational land reclamation and extensive irrigation have led to the obvious contradiction between water and land resources. Based on the present agricultural development background, nine factors of Zhangye oasis agriculture system were chosen and analyzed. Firstly, we used the principal component analysis to investigate the impacts of different factors on oasis agriculture. Secondly, taking agricultural output as a reference indicator and others as comparable indicators, the correlations of each factor and oasis agriculture were analyzed based on grey relative analysis method. Summarizing the results of two methods, we bring up four measures to coordinating the development of Zhangye oasis agriculture.
