摘要
对贵州不同产区油茶果实性状进行了分析,结果表明:果实数量性状的平均变异系数31. 63,变异范围10. 14～60. 91,变动区间较大。将贵州油茶的果形分为3类,第一类为桔形,果形指数值在0. 850～0. 873之间,占所选果实的12%;第二类卵形,果形指数值在1. 078～1. 118间,占所选果实的40%;第三类为球形,果形指数值在0. 900～1. 072间,占所选果实的48%。果色分为6类。果实性状在不同产区间的F值存在显著性差异,可用果实性状进行优树选择。
The fruit traits of Camellia oleifera in different producing areas of Guizhou were analyzed.The results showed that the average variation coefficient of fruit quantitative traits was 31.63,the variation range was 10.14~60.9,and the change interval was large.The fruit shapes of camellia oleifera in Guizhou were classified into three types.The first was orange-shaped,and the fruit shape index value wasbetween 0.850~0.873,accounting for 12% of the selected fruit; The second was oval,and the fruit shape index value was between 1.078~1.118,accounting for 40% of the selected fruit; The third kind was spherical,and the fruit shape index value was between 0.900~1.072,accounted for 48% of the selected fruit .The fruit color was divided into six categories.The Fvalues of fruit traits in different producing areas were significantly different,and the fruit traits could be used for superior tree selection.
