温室黄瓜早熟性状的相关分析

Correlation Analysis to Early Maturing Traits of Cucumber in Greenhouse

对温室黄瓜20个品系的早期产量进行了单因素方差分析,结果表明,20个品系之间的早期产量存在显著差异。对与早熟性相关的6个农艺性状进行了相关分析,结果表明,第一雌花节位、播种至第一雌花开放日数、播种至始收日数与早期产量呈负相关,并都达到显著水平,而且前二者与早期产量之间均达到了极显著水平;采瓜数和雌花节率与早期产量呈正相关且都达到了极显著水平;单瓜质量与早期产量呈负相关,但不显著。

In the paper single factor variance analysis of 20 cucumber lines was conducted and the results showed great difference existed among them.In addition the correlations analysis to 6 early maturing traits was conducted,too.The results showed that,knot position of the first female flower,days from sowing to the opening of the first female flower,days from the sowing to the first harvesting,all showed negative correlation with the early yield and all reached at significant level.Especially the formal two terms reached great significant level.The number of the collected cucumber and female flower knot rate showed great significance with the early yield,while the single cucumber yield showed positive correlation with the early yield,but not so significant.
