摘要(Abstract):

目的 :研究干旱胁迫对甘草生长的影响及其抗旱性。方法 :采用土壤干旱胁迫处理二年生甘草 6 0d ,测定地上茎叶和地下根及根茎各生长指标以及生物量。结果 :随干旱胁迫程度的增强 ,甘草地上地下各器官生长均受到抑制 ,但对地上器官的生长抑制更加明显。结论 :干旱胁迫对甘草生长的抑制作用具有明显的器官特异性 ,在土壤相对含水量为 5 0 %的干旱条件下 ,人工种植甘草的产量和质量可兼顾。
Objective: To study the effect of drought stres s on the growth of Glycyrrhiza uralensis and its drought resistance characte ristic. Method: The growth in dicators of G. uralensis in cluding leaf, stem, root and biomass were measured when two-years-old G. uralensis had lived in drought stress soil for 60 days. Result: The growth of all organs of G. uralensis was restrained because of drou ght stress, especially to up ground organs. Conclusion: It is obvious that the restraining effect of drought stress on G. uralensis poss esses organ speciality. Both yield and quality of G. uralensis will be sat isfied when it grows in the soil with relative water content of 50%. [
