与黄瓜早熟性有关的主要农艺性状的相关与通径分析

STUDIES ON CORRELATION AND PATH ANALYSIS OF THE MAIN AGRONOMIC CHARACTERS WITH RELATION TO PRECOCIAL OF CUCUMBER

对与早熟性相关的 12个农艺性状进行相关性和通经分析。相关分析表明 ,采瓜数、座瓜率与前期产量呈极显著正相关 ;第一雌花花期、始收期与前期产量呈显著负相关。通经分析表明 ,商品瓜日增克数、座瓜率、采瓜数、第一雌花花期对前期产量有直接效应 ;始收期对前期产量有间接效应。

Correlation and path analysis of twelve agronomic characters with relation to precocial of cucumber were studied. Correlation analysis showed that fruits number and setting ratio were positively correlated with early yield. While the first female flower florescence,the period of first harvest were interrelated negatively. Path analysis showed that early yield was affected positively by four characters: weight increasing per day of commodity fruits, setting ratio of fruits, fruits number and first female flower florescence.It was also interdirectly effected by period of beginning to harvest.
