干旱胁迫对柔枝松幼苗水势的影响
Effect of Drought Stress on the Water Potential of Pinus flexilis James Seedling
摘要
Abstract
[ Objective ] The theoretic basis of the dtought-tolerance of Pinus flexilis James was provided through the study on its water potential of the seedlings of Pinus flexilis James.[Method ]the water potential of the seedlings of sex species o Pinus flexilis James under the different drought periods was measured. [Results] The results indicated that during the whole period of drought the content of moisture in soil covered by the seedlings of six species basically decreased and the decreasing trendy of the water potential in soil covered by the seedlings of Rs and Rsd was slow, which decrement was 1.10 and 1.13 MPa compared with normal one. The decreasing trendy of the water potential in soi covered by the seedlings of Rs was quick and in the soil covered by the seedlings of Rsd the recovery of the water potential was slow ater irrigation. [Conclusion] The Pinus flexilis James was the plant with the drought-tolerance, which could delay its dehydration under the condition of high water potential and the species of Rsi and Rsd were with stronger drought-tolerant.关键词
