| Research Abstract |
Studies on osmo-regulation mechanisms and improvement of drought and salt tolerance of plants were conducted for revegetation in arid areas. Types and amount of osmolytes (including Betains, Sugars, Sugar alcohols and Amino acids) accumulated in leaves were varied widely among plants growing in drylands of China. To enhance the salt tolerance of plants, we applied a stress acclimatization treatment to seedlings for 2 days by adding polyethylene glycol (PEG) to the culture solution. As for the results of experiments, 2-day stress acclimatization treatment could improve salt tolerance of seedlings enough to adapt them to a lethal concentration of NaCl.
