【摘要】 因子分析法把决定番茄早熟性的13个结构性状综合成花果发育速度因子、早期孕果因子、熟果因子、花数孕育因子、低节位因子、果数密度因子和封顶因子。进一步分析结果表明番茄早熟性主要由品种的花果发育速度因子、早期孕果因子和熟果因子决定的;标志番茄早熟性的最佳性状是第一花序第三朵花的开花期、第1-2穗的座果数,一定时期的熟果总数。最后得出选择番茄早熟品种(单系)的参考模型。更多还原

【Abstract】 The thirteen early-maturing structure characters of tomato can be combined into seven principle factors-growing velocity on flowers and fruits, early bearing fruits, ripening fruits, bearing flowers, lowering node, and density of fruits and sealing top by the factor analysis. The result showed that the early-maturing of tomato is decided by the factors of the growing velocity on flowers and fruits, early bearing of furits and ripening fruits. There are three best sign characters on early-maturing of tomato, which are the bloom of the third flower on the first infloresense, the number of fruits set on the first and second cluster and ripen fruits in certain period. A election model of early-maturing variety and strain of tomato is got at last.更多还原
