摘　　要：利用分别添加FZB-42、GM及Bio菌剂的基质培育黄瓜幼苗,研究其在12℃低温下贮藏3、6、9、12 d后黄瓜幼苗叶绿素含量、净光合速率、生物量以及贮藏后光合速率恢复情况等。结果表明:FZB-42和Bio能增加黄瓜幼苗叶绿素含量,保持较高的光合速率,黄瓜幼苗低温贮藏后其光合速率能较快地恢复到正常生长植株的水平。同时,FZB-42处理黄瓜幼苗MDA含量相对较低,表明细胞膜结构受破坏程度低。FZB-42和GM处理在低温贮藏期间能使黄瓜幼苗保持较稳定的鲜质量,幼苗长势整齐。Seedling substrates were mixed with various amounts of Bacillus amyloliquefaciens,Glomus mosseae and a commercial bio-fertilizer prior to sowing,in order to evaluate the low temperature(12 ℃)storage effect and photosynthesis speed recovery process of Cucumis sativus seedlings after varied storage time(3 d,6 d,9 d,12 d).The results showed that Bacillus amyloliquefaciens and Bio can improve chlorophyll content and photosynthesis speed during storage.Bacillus amyloliquefaciens treatment could speed photosynthesis recovery process of seedlings after low temperature storage,so that the seedlings were able to grow like normal plant.At the same time,MDA content was relatively low when the seedlings were treated by FZB-42.This indicated that the damage of cell structure was also low.Glomus mosseae and FZB-42 treatments would enable cucumber seedlings to keep stable freshness during low temperature storage and to grow in trimness.
