摘要
以广西普通油茶种源球果为试材，对18个广西普通油茶种源间的球果形态相关的直径、果高、高×径、高／径4个性状的变异进行了分析。结果表明：广西油茶球果形态相关的4个性状变异系数在Ii．731%～20．581％，球杲直径和高×径的差异在种源间达到显著水平和极显著水平，球果高度和高／径2个性状没有达到显著水平，球果直径和高×径在群体间存在一定的分化，而球果高度和高／径的变异基本上都在群体之内；球果直径和高度存在极显著的正相关；并通过聚类分析将18个种源分为3类。
Taking cones of Camellia oleifera among proveniences in Guangxi as test material, the morphology related to diameter, height,height X diameter, height/diameter variation in size of 4 traits of 18 resources were studied. The results showed that the coeffient of variation of 4 fruit shape-related traits ranged from 11. 731% to 20. 581%, extremely significant difference among proveniences existed for diameter, significant difference for height X diameter. The differences were not significant for height and height/diameter. There were differentiation among proveniences for diameter and height X diameter, and less differentiation for height and height/ diameter; extremely significant correlation between diameter and height; 18 proveniences were subdivided into 3 groups based on the information of fruit shape.
