摘要： 为研究黄瓜种子含油量与耐低温性的关系,摸索鉴定黄瓜耐低温性的方法,给予9504,9524,9507,9508,9512,9518,9521,9506,9511等9份不同来源的黄瓜材料白天12℃,晚上8℃的低温处理,每天光照7.5 h,强度为30μmol/(m2.s),约合2 000 lx,共处理14 d,对耐寒性进行分级,并计算耐寒指数,测定种子含油量,发现两性状在材料间表现不同,经方差分析表明种子含油量、耐寒指数在材料间差异极显著,在区组间差异不显著,进一步进行相关分析表明种子含油量与苗期耐寒指数的相关系数为0.770 0,达显著正相关,说明种子含油量与耐低温性的关系密切,可作为黄瓜耐低温性的间接鉴定指标之一。

Abstract: In order to study the relationship between oil content in cucumber seeds and chilling tolerance index,we probed into the method for appraising chilling tolerance.9 different cucumbers which 9504,9524,9507,9508,9512,9518,9521,9506 and 9511 are given at 12℃ in the daytime and at 8℃ in the evening.Those are shined 7.5 h everyday by the light that the strength is 30 μmol/(m2·s) or 2 000 lx and have been handled for 14 d.We classed the cucumbers with resistance of low temperature,calculated their chilling tolerance index and oil content in seed and two characters were found difference between materials.The investigations of oil content in seed and chilling tolerance index expressed by variance analysis that two characters were differences significant between materials,and were insignificant between blocks.The related analyses indicated that the related index between the oil content in seed and chilling tolerance index is 0.770 0,reaching to positive correlation,which explained that the oil content in seed can be one of the indirect index signs of chilling tolerance character of cucumber.
