水分胁迫对不同种源黄柳幼苗生长特性的影响

摘要

Water stress experiments on six Salix gordejevii provenances were conducted. The result showed that the morphological changes of the six Salix gordejevii provenances was similar in the course of water stress. Height - growth and total biomass was restricted, but bellow - ground biomass and root/ shoot ratio was inereaseing with the enhance of water stress.%以6个种源的黄柳幼苗为试验材料，采用盆栽控水的方法，开展水分胁迫试验的结果表明：受到水分胁迫后，各种源表现出的胁迫症状基本相同；高生长、茎生长明显受到抑制；单株生物量随着水分胁迫程度的增加而减小，地下生物量和根冠比随着水分胁迫程度的加剧呈增加的趋势。
