According to the special surrounding of rock slopes, two native plants (Pogonatherum panideum(Lam.)Hack) and (Erioophorum comosum Nees ) cultivated in the pot and PEG solution was used as study material to study their drought resistance in this experiment, comparing to Cynodon dactylon that is usually applied on the slope eco-engineering. The changes of the plants' morphologies and physiologies were studied under drought-stress. The purpose of this experiment is to find theoretical foundation for applied on...
