Abstract：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．
