Drought resistance and transplanting of 8 plants in South China

Taking 8 wild grand cover plants in South China as study objects, physiological indexes of their leaves, including relative water content, relative electric conductivity and malondialdehyde(MDA) content were measured, based on a water-controlled pot experiment. And a comprehensive evaluation on drought resistance of these 8 plants was also conducted, using subordinate function method. Meanwhile, these plants were transplanted into the garden for a one-year phonological observation, and cottage and seeding tests on part of plants. The results showed that, Dichondra repens, Desmodium triflourum and Alysicarpus vaginalis are excellent ground cover plants, because they have a relative stronger drought tolerance, easier to propagate, and higher turf-establishment speed. The drought tolerance of Hgdrocotyle sibthorpoilides, Centella asiatica and Melastoma dodecandrum is slightly weaker, but they can keep a good coverage and landscape effect at all seasons. The drought tolerance of Lobelia chinensis and Viola inconspicua is the worst in 8 plants, but their flowers are very beautiful. So they can be used as good ground cover plants for viewing flowers, grown under thin arbors to form a good landscape.
