Study on selection and evaluation for turf grass in greenhouse condition

In order to select the turfgrass or varieties that were suitable for greenhouse condition, the heat tolerance and shade tolerance of eight turfgrass species were studied by the comprehensive evaluation of morphological index, physiological index and molecular index. The results showed that: 1) Zoysia matrella and Cynodon dactylon×C. transvadlensis grew best and mignt be optimal species to plant in greenhouse. Z. Japonica, Lippia nodiflora, Paspalum vaginatum, Eremochloa ophiuroides, Agrostis stolonifera, P. notatum did not perform well in greenhouse. 2) The results of comprehensive evaluation for turf resistance by fuzzy clustering analysis were consistent with the morphological index. Z. matrella and C. dactylon×C. transvadlensis ‘Tifgrand' were regarded as the best speices. 3) Meanwhile, the expression of the gene PP2A and GAPDH can also reflect the adaptation ability of turfgrass to greenhouse condition. It was similar to the results of morphological appearance and physiological quality evaluation. Thus, it also improved turfgrass quantitative evaluation and standard system in greenhouse condition.
