| 摘 要： | 通过去雄花套袋、自花授粉、自然异花授粉,不同时期疏果,以及花粉萌发力的测定,研究了闽焦64-1、闽焦64-2的座果和焦核率情况。结果表明：焦核品种的花粉大部分败育,花粉萌芽率均低于大核品种;焦核龙眼无单性结实特性,异花授粉是其座果所必需的;在并粒期与关公刀粒期疏大果有利于提高焦核率。

| Abstract: | The fruit setting and embryo abortion rate of aborted-seeded Longan cultivar "Min Jiao 64-1"and" Min Jiao 64-2" were studied by using different pollination methods,different fruit-thinning time and measuring pollen germination rate.The results showed that most of the pollen of aborted-seeded cultivar were aborted,which germination rate was lower than cultivars with normal embryos.Aborted-seeded longan didn't have parthenocarpy ability.Cross-pollination was necessary for the fruit setting of aborted-seeded longan.In the periods of "Binli"and "Guangongdaoli",fruit-thinning had the advantages to raising seed-abortion rate. |
