生长环境对刺五加生理生化及光合作用的影响

The Effect of Different Environment on Physiological,Biochemical and Photosynthesis of Acanthopanax senticosus

比较了全光、林缘和林下生长环境下栽培刺五加对其丙二醛(MDA)、可溶性糖、叶绿素的含量,过氧化物酶(POD)的活性及光合速率的影响。结果表明:全光照过氧化物酶的活性和可溶性糖含量显著高于林缘和林下,而丙二醛含量各组间无差异;过氧化物酶的活性和可溶性糖季节含量变化与丙二醛含量呈明显的负相关。在移栽后保证水分的条件下,全光照不会对刺五加造成损害。

The contents of malondialdehyde（MDA）, soluble sugar and chlorophyll, the peroxidase（POD）activity, photosynthetic rate were compared with different environment such as farmland, forest edge, understory and water stress. The results showed that POD activity and content of soluble sugar were higher than that of forest edge and understory, and MDA content have no difference between two conditions. The annual change of POD activity and soluble sugar content were correlated to the MDA content negatively. Under certain moisture content condition, A. senticosus can live on farmland without any damage.
