Abstract

To understand drought tolerance in Mucuna sempervirens, physiological and morphological expression studies were done on three species of liana(Hedera nepalensis var. sinensis, and Euonymus fortunei) with polyethylene glycol(PEG) 6000 concentrations of 50 g·L-1 and 200 g·L-1 for 0(the control), 1, 3, and 5 d. All of the samples were two-year-old seedlings. Results showed that leaf water content and the rate of dehydration decreased, but water saturation deficit, electrolyte leakage, and free proline increased significantly(PM. sempervirens was significantly(PH. nepalensis var. sinensis and E. fortunei. Synthesize all of the indexes, drought resistance of the three lianas was E. fortunei > M. sempervirens > H. nepalensis var. sinensis. During the stressed period, proline content and SOD activity of M. sempervirens increased to resist drought and protect the cell membranes.
