Membrane Cushion Seedbed to Improve Potato Seedlings Disaster Resilience for Winter Training
Abstract：With no membrane cushion seedbed for the contrast,the effect of entire membrane cushion seedbed and holes membrane cushion seedbed＇s on biomass composition,photosynthetic efficiency,osmotic adjustment performance and lipid per-oxidation damage of winter Potato seedling were researched.The results showed that： ①membrane cushion seedbed accelerated potato plant height,leaf area,root,stolon and tuber growth at different growth stages;②membrane cushion seedbed caused the potato net photosynthetic rate,transpiration efficiency and Pro content increased;③in different modes of seedbed,the potato leaf MDA content was： no membrane cushion,entire membrane cushion,holes membrane cushion,root MDA content was： entire membrane cushion,no membrane cushion,holes membrane cushion.It concluded that membrane cushion seedbed could accelerate potato growth,enhance osmotic adjustment and photosynthetic efficiency,moreover,holes membrane cushion seedbed could induced lipid per-oxidation damage of winter training in circumstance of lower temperature,weak light and high humidity.
