摘要:
根茎是根状茎型克隆植物的特有结构,在养分储存、运输和分蘖茎的形成等方面起关键性作用。然而有关根茎生理学方面的研究却十分匮乏。为了探讨根茎在植物感应环境胁迫中的作用, 本文以羊草(Leymus chinensis)为实验材料,研究和比较了短期NaCl胁迫根、根茎、根和根茎3种处理方式下羊草对盐胁迫的响应。试验结果表明:200 mmol·L-1 NaCl处理羊草根、根茎、根和根茎24 h,显著(p<0.05)降低羊草叶片净光合速率和蒸腾速率,增加叶片渗透浓度与脯氨酸含量;其中同时处理根和根茎叶片,蒸腾速率和净光合速率的降低程度显著高于分别处理根和根茎。在分别处理根与根茎的情况下,叶片含水量、脯氨酸含量、净光合速率、蒸腾速率均无显著性差异。不论单独胁迫根、根茎还是同时胁迫根和根茎,羊草根、根茎和叶片内Na+含量都显著高于对照,而羊草根、根茎和叶片内K+含量都显著低于对照。这些结果显示:1)根茎在羊草响应盐胁迫的生理过程中与根系具有类似的功能;2)羊草根茎在盐胁迫条件下能够有效地吸收Na+;3)鉴于根茎的生物量和表面积都明显地低于根系,在盐胁迫下羊草根茎吸收Na+的效率高于根系。
