Eight varieties of vitis amurensis rupr . ( v . t . r ) of intraspecific hybridization and interspecific hybridization were introduced into from 2001 ~ 2006 , the results showed some which suited the temperature and soil condition to be the main varieties were selected from those varieties with cold - resistance and high yielding . " zuo youhong " was for dry - red wine , " hasang " was for fruit juice and " shuang you " and " shuang hong " were for adjusting color and acid 摘要2001 ~ 2006年,引种8个山葡萄种内和种间杂交品种,筛选出适宜当地气候和土壤条件、抗寒、产量高、可酿造干红葡萄酒“左优红” 、加工果汁饮料的“哈桑” 、用于调色和调酸的“双优”和“双红”为当地主栽和推广品种。
In this paper , observation was conducted on pollen germination and growth behavior in distant hybridization between cerasus fruticosa and c . avium and hybridization between varieties in c . fruticosa through fluorescent light system of microscope . the results showed that pollens could normally germinate and pollen tubes could reach ovary through style to completed fertilization in intraspecific hybridization in c . fruticosa . the average fruit - set rate was 27 % 通过对草原樱桃与欧洲甜樱桃种间远缘杂交及草原樱桃品种间杂交后花粉管行为的荧光观察发现,草原樱桃品种间杂交授粉后花粉在柱头上能正常萌发生长,花粉管沿花柱到达胚珠完成受精过程,平均座果率为27 。
