However, only did a few pollen germinate in inter - specific hybridization between cerasus fruticosa and c. avian and many pollen tubes are crosswise on stigma and couldn " t penetrated into style. although a few pollen tubes entered, they couldn " t continue to grow due to accumulation of callosity in pollen tubes. in view of above - mentioned results, the irregular growth of pollen was the main reason to cause the incompatibility of distant hybridization between cerasus fruticosa and c. avium
而草原櫻桃與歐洲甜櫻桃種間雜交授粉后花粉在柱頭上雖少量萌發,但花粉管在柱頭上橫向生長,或盤繞,扭曲不能伸入花柱;個別進入花柱的花粉管先端因沉積胼胝質而中途停止伸長未能進入子房到達胚珠,從而說明這種雜交授粉后花粉管的不正常行為是導致草原櫻桃與歐洲甜櫻桃遠緣雜交不親和的主要原因。The new types formed through cross breeding can combine the fine qualities and forms of two or more than two parents and become new biological types of higher productivity which are also more resistant to unfavourable conditions
