Abstract

Abstract: Nine varieties of Camellia oleifera mainly planted in Tongren City, Guizhou Province were divided into large, medium and small camellia fruits according to the fruit diameter, and their related economic characters were measured, and the effects of different varieties with different fruit diameters on their economic characters were analyzed. The results showed that different fruit diameters had obvious effects on various economic characters of Camellia oleifera. From the fresh seed rate of Camellia oleifera, Huashuo, Changlin 40, Cenxiruanzhi, Xianglin 210 and Changlin 53 cultivated large fruits, and Huajin and Huaxin cultivated medium fruits, all of which could improve the fresh seed rate. Judging from the kernel-fruit ratio of tea seeds, Huashuo and Changlin 4 cultivated medium fruits, while Huajin, Huaxin, Changlin 40, Cenxiruanzhi and Changlin 18 cultivated large fruits, all of which were relatively high with the kernel-fruit ratio of tea seeds; judging from the oil content of seed kernel, Huajin, Changlin 40 and Xianglin 210 cultivated big fruits, while Huashuo, Changlin 4, Cenxiruanzhi and Huaxin cultivated middle fruits, which were beneficial to the accumulation of seed kernel oil; the oil content of seed kernel was extremely significant positively correlated with fresh seed yield, positively correlated with kernel yield, extremely significant negatively correlated with seed moisture content and negatively correlated with single seed weigh; the oil yield of 100 g fresh fruit was extremely significant positively correlated with fresh seed rate and kernel oil rate, positively correlated with fruit shape index and kernel rate, and extremely significant negatively correlated with seed moisture content. Therefore, in order to cultivate high yield, Huajin, Changlin 40, Cenxiruanzhi, Xianglin 210 and Changlin 53 could cultivate large fruits by thinning small fruits, while Changlin 18, Changlin 4, Huaxin and Huashuo could not take any fruit thinning measures.
