Abstract: The fruit and seed morphological characters of Camellia nitidissima and Camellia euphlebia were investigated. The results were as follow: (1) The average single fruit weight of two species were 32.50 and 25.79 g, the shape of fruit(FT/FD) were 0.73 and 0.61, the average single seed weight were 2.87 g and 2.62 g, the shape of seed (SL/SD) were 0.76 and 0.75, the fruits and seeds of two species were oblateness; (2) The average seed number per fruit concentrated mainly on ranged from 2 to 8, the maximum value was 11; (3) The average seed number per fruit of each species was a negative relation between the average single seed weight and seed germination rate. The average single seed weight was positively related to seed germination rate.

摘要: 对普通金花茶Camellia nitidissima、显脉金花茶C. euphlebia的果实、种子进行研究。结果表明:(1)两种金花茶果实均重分别为32.50 g和25.79 g,果实整体形态值(FT/FD)分别为0.73和0.61,果实均为扁圆形,种子均重分别为2.87 g和2.62 g,种子整体形态值(SL/SD) 分别为0.76和0.75,种子亦偏扁;(2) 每颗金花茶果实的种子数一般为2~8粒,最多为11粒;(3) 经统计分析,两种金花茶的每果种子数与种子均重、种子发芽率呈负相关关系,种子均重和种子发芽率呈正相关关系。
