通过对柑桔属14个种20个品种的花器解剖观察,分析得出花辦长度、宽度,花蕾长度及花药长度、长宽比值可作“柑桔三属左右线分类系统表”中左右线柑桔分类的依据。肯定了左线柑桔为大花型、长药囊;右线柑桔为小花型、短药囊的理论。而花丝离合程度以及花辦和花蕾的长宽比值,左右线之间差异不显著,不能作为分类依据,因而关于“右线柑桔为花丝结合型、左线为花丝分离型的理论”值得商榷。
Through analyzing the flower organ of 14 species and 20 species of citrus, the length, width, length of flower bud and length of anther and length-width ratio can be used as the left and right lines in “Citrus three genera and line classification system table” Citrus classification basis. Affirmed the left line of citrus large flowers, long sachet; right line of citrus flowers, short sachet theory. However, the degree of filament and the length-width ratio of flower buds and flower buds are not significantly different between the left and right lines, which can not be used as the basis for classification. Therefore, it is worth discussing that “the right line of citrus is filiform type and the left line is of filament type” .
