摘要
以4年生刨花楠扦插苗叶片为实验材料,模拟低温环境,研究刨花楠在低温下的生理生化变化。研究结果表明:随着处理温度的降低,细胞相对电导率先上升后下降,POD活性先下降后上升,SOD活性和可溶性糖以及游离脯基酸含量先上升,再下降,最后又上升,MDA含量先下降,再上升,最后又下降。
Simulating chilling environment and using the leaf of 4-years old seedling of Machihs pauhoi, the physiological and bio-chemical characteristics change of M. pauhoi in chilling was studied. The results are as follows： the cell relative permeability increased first and then decreased with the temperature dropping; the activity of POD decreased first and increased later, the activity of SOD, content of soluble sugar and PRO increased first, then decreased, increased at last; the content of MDA decreased first, and then increased, decreased at last.
