Abstract

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.

Key words: Cucumber, Chilling tolerance, Oil content in seed, Variance analysis, Correlation analysis
