摘要

一般檬果花粉在1%瓊脂，22%蔗糖之人工培養基卽可發芽良好，Brewbaker與Kwack配方之培養基未能增加花粉發芽率。花粉發芽對溫度極爲敏感，在培養基中(in vitro)花粉發芽率於15℃時幾乎爲0，20℃時發芽率仍低，25℃才能發芽良好。在花柱中(in vitro)，25℃時則花粉發芽良好，約經4小時花粉管之生長卽可達胚囊。

Mango pollen germinated well in artificial medium containing 1% agar and 22% sucrose, but did not have any improvement on medium suggested by Brewbaker and Kwack. Temperatures severely affected pollen germination. Pollen germination was almost zero at 15℃, low at 20℃ and high at temperatures above 25℃, in vivo studies showed that pollen tube could reach embryo sac about 4 hours at 25℃.
