以8个黄瓜品种为试材，研究了弱光条件下亚适温对黄瓜幼苗生长及抗氧化酶活性的影响。结果表明，弱光条件下经过14 d亚适温处理后，‘津优5号’、‘津优1号’、‘沃优2号’和‘津优35号’长势较好；与适温对照相比，这4个品种电解质渗漏率增加较小，叶绿素（ a＋b）含量降低较小，可溶性蛋白质含量和抗氧化酶活性增加较大。表明在弱光条件下这4个品种对亚适温的适应能力优于其它参试品种，适宜在我国北方冬季日光温室栽培。

The effects of low light and suboptimal temperature on growth and antioxidant enzyme activi-ties of cucumber seedlings were studied with eight cucumber varieties as experiment materials .The results showed that Jinyou 5 , Jinyou 1 , Woyou 2 and Jinyou 35 grew better after treated for 14 days under low light and suboptimal temperature;compared with optimal temperature , the increase of electrolyte leakage of the four varieties was smaller , while those of soluble protein content and antioxidant enzyme activities were larger , and the content of chlorophyll ( a+b) decreased a little .All these indicated that the adaptability of the four varie-ties to suboptimal temperature under low light condition was superior to the others , so they were suitable for cultivation in solar greenhouse in winter of northern China .
