水分胁迫对茶条槭幼苗生长的影响
|
摘要
本文研究了水分胁迫对茶条槭幼苗生长的影响,结果表明,水分胁迫对茶条槭幼苗高生长的影响较大,对径生长影响较小。随着土壤含水量的降低,叶长、叶宽和叶面积显著降低,叶片对水分变化较为敏感。在干旱胁迫下,茶条槭生物量积累和分配也发生了变化,总生物量显著下降,根的比重增大,根茎比显著升高。
This paper studied the effect of water stress on the growth of Acer ginnald seedlings. The results showed that water stress had great influence on the growth of seedlings,and had little effect on diameter growth. With the decrease of soil water content,leaf length,leaf width and leaf area decreased significantly,and leaves were more sensitive to water change. Under drought stress,the accumulation and distribution of biomass of A. ginnald also changed,the total biomass decreased significantly,the proportion of root increased,and the ratio of root to stem increased significantly.
