Effects of Water Stress on the Growth of Handeliodendron bodinieri Seedling
[Objective] To clarify the adaptation ability of plants to water content environment factor change under the conditions of water stress. [ Method]The effect of water stress on the growth of one-year-old seedlings of Handeliodendron bodinieri was studied through potted experiment. [ Result]The results showed that processing ⑤could not provide the necessary water to grow of seedlings, all seedlings withered and died. The seedlings growth was normal with processing ①、②. A large number leaves of processing ③seedlings became yellow and wilt, under processing ④, lots of leaves shedded and its survival rate was 30% after 40 days water stress. With the soil moisture decreasing, the growth quantity of seedlings height, diameter, number of leaves took on reducing trends, but tuber index increased and the reduced amount of leaves were largest. The biomass distribution of various organs was in order; root > leaf > stems. [ Conclusion] The growth trends of plant seedling underground portion is better under the conditions of water stress.
