摘要： 研究不同贮藏温度(17,12,7℃)对黄瓜秧苗产后主要质量指标的影响,结果表明,12和17℃下贮藏的秧苗较其他贮运温度的秧苗质量好,根系活力、叶绿素含量两项生理指标都下降较小,MDA上升幅度小。干质量最大,地上地下部分生长平衡,定植后秧苗的心叶生长速度表现最快。但是贮藏6 d后12℃下的黄瓜秧苗品质优于17℃。

Abstract: The effect of different storage temperature( 17, 12, 7 ) on the main quality index of cucumber seedlings during storage was studied.The result showed that below 12 and 17, the two physiological indexes( activity of root vigor and chlorophyll content) dropped less, the MDA and Pro rose less, the seedlings had the greatest dry weight, the growth above and underground kept balance, and the growth speed of the central leaves was faster after transplanting. But the seedlings stored in 12 grew better than in 17 after 6 d of storage.

Key words: Cucumber, Plug seedling, Storage temperature, Seedling quality
