水分胁迫对地被植物体内叶绿素含量的影响

摘要

摘要：通过在自然干旱和覆水等不同水分胁迫条件下，研究对绢毛匍匐委陵菜（Potentilla reptans L．）和蛇莓（Du-chesnea indica）等地被植物叶片叶绿素含量的影响变化。结果表明，绢毛匍匐委陵菜和蛇莓对水分胁迫有较强的适应性，承受时间可长达20d，其中绢毛匍匐委陵菜的耐旱性优于其耐涝性，而蛇莓的耐涝性优于其耐旱性。%Under natural drought ＆ water stress, effect of chlorophyll for cover plants, such as Potentilla reptans L. ＆ Duch- esnea indica were studied. Result shows that ： PotentiUa reptans L. ＆ Duchesnea indica have stronger adaptability on water stress for 20 d. Drought tolerance of Potentilla reptans L. is optimal than its waterlogging tolerance. Waterlogging tolerance of Duchesnea indica is optimal than its drought tolerance.
