| 摘 要： | 余甘子的雌雄花着生在结果枝叶腋内,雌花着生位置一般在1-6叶腋内,着生频率最高的是2~4叶腋,雄花分布在4~12叶腋内。余甘子雌雄花主要分布在一龄结果母枝上。雌花在结果枝分布,最多的扁甘品种平均有5.72朵,最少的是六月白为0.882朵。雌花丛生性强的扁甘、山甘、兰丰、粉甘和秋白具有较高产性状,而六月白则不具有丰产性。扁甘为单个结果枝上雄花最多的品种,平均达221.92;最低的是六月白,雄花数只有14.91。余甘子树龄越高,雌花分布越不均匀。余甘子树冠分为3种类型:半圆形树冠,雌雄花在树冠中的分布比较均衡,有花冠层占总冠层比例达92%,产量最高;扁平形树冠,有花冠层占总冠层比例为62%;倒三角形树冠,冠内雌雄花分布极不均衡,有花冠层占总冠层比例只有41%。

| Abstract: | The flowers of Phyllanthus emblica L.set in the axil of the branchlets.Generally,the female flowers set in the 1~6 axils,but mostly in the 2~4 axils.The staminate flowers are distributed in the 4~12 axils.The flowers of Phyllanthus emblica L.mainly are distributed on annual indeterminate shoots.The mumber of the female flowers of Biangan, which has most female flowers,is 5.72 averagely,and that of Liuyuebai,which has fewest female flowers,is 0.882.Biangan,Shangan,Lanfeng,Fengan and Qiubai,whose female flowers have stronger fascicular characters,have fertile characters,Liuyuebai hasn't strong fertility.The average number of staminate flowers of Biangan,which has most staminate flowers on branchlets' is 221.92,Liuyuebai,the variety of fewest staminate flowers is only 14.91.The older the age of Phyllanthus emblica L.,the more asymmetric the female flowers'distribution.The tree crown's figure of Phyllanthus emblica L.can be divided into three types,the flowers' distribution of the semicircle crown is quite uniform,the flower layer occupy 92% in all the crown,so the output of this type is the highest;the flower layer's proportion of the flat crown is 62%;the flower layer's distribution of the delta crown is very asymmetrical, and the proportion of flower layer is only 41%. |
