摘要
对十二个柚品种花粉发芽率、畸形率、生活力及花粉量的测定结果表明：它们的花粉育性存在一定差异，可划为四种类型。其中晚白柚、四季抛、梁平柚属高育型，麻豆文旦柚、文旦柚、五布柚、垫江柚、沙田柚、蓬溪柚为中育型，金香柚、漳州柚、台北柚为低育型。本试验未见有不育型。
Pollen germination rate, abnormality rate, viability and pollenamount per anther are detected in twelve pumelo cultivars. The resultsshow that there are differences in pollen fertility of these cultivars.They are divided into four kinds. Wanbei Pumelo, Si ji pumelo, andLiang ping pume1o have high fertility. Madou pumelo, Wengdan pumelo,Wubu pumelo, Dianjiang pumelo, Shatian pumelo and pengxi pumelo havemiddle fertility. Jinxiang pume1o, Zhangzhou Pumelo and Taibei pumelohave low ferti1ity.
