摘　　要：以津春5号黄瓜为材料，设高温、高湿和高温、常规湿度2个处理，与常规黄瓜生产管理为对照，在CO2施肥条件下，每天中午时段平均40-50℃下处理4h以上。结果表明：高温处理区黄瓜株高、茎粗、叶片数和叶面积等指标与对照差异显著，且高温、高湿处理区除茎粗外其它三项指标与高温、常规湿度处理区差异显著，高温、高湿对黄瓜的商品质量有一定的提高，高温、常规湿度使弯曲瓜增多；黄瓜叶片中可溶性蛋白含量呈降低趋势，游离脯氨酸、超氧化物歧化酶及丙二醛含量均呈升高趋势，且高温、高湿区变化幅度小于高温、常规湿度区。The test materials were “Jin-chun No.5” cucumber, through high temperature and bigh humidity treated and high temperature and normal humidity treated, and as normal management of cucumber for CK, under CO2 enrichment, during treated by high temperature for more 4 hours in noon daily average of 40℃-50℃. The indexes of height of plant, rough degrees of stem, number of leases and leaf area in high temperature was different from CK, and except for rough degrees of stem, the other indexes were also different from high temperature and normal humidity treated, so the treats of high temperature and high humidity could also accumulated yield and quality of cucumber, but the treats of high temperature and normal humidity could increase bending cucumbers; content of protein trended to go lower in leaf of cucumber, contents of SOD, MDA and proline of all cucumber varieties trended to go higher, and the change of high temperature and high humidity treated was lower than high temperature and normal humidity treated.
