‘粉蓝’兔眼蓝莓适宜授粉品种的筛选

Screening of the Appropriate Pollinizer of Rabbiteye Blueberry Cultivar‘Powderblue'

以蓝莓‘杰兔’、‘芭尔德温’和‘蒂芙蓝’为授粉品种,对‘粉蓝’进行异花授粉,以其自花授粉为对照,研究了不同授粉品种对‘粉蓝’坐果率和果实性状的影响,以期为其栽培中选择授粉品种提供参考依据。结果表明:‘粉蓝’兔眼蓝莓虽然具有一定的自交亲和性,但自交后坐果率偏低且显著低于异花授粉,以‘杰兔’和‘芭尔德温’为授粉品种的坐果率显著高于用‘蒂芙蓝’作为授粉品种的坐果率。同时以‘杰兔’和‘芭尔德温’为授粉品种获得的果实单果重与可溶性固形物含量均显著高于用‘蒂芙蓝’授粉和‘粉蓝’自交获得的果实。这些结果表明‘杰兔’和‘芭尔德温’为‘粉蓝’较适宜的授粉品种。

With rabbiteye blueberry cultivars‘Tifblue＇,‘Premier＇and‘Baldwin＇as pollination varieties,cross-pollination experiment was conducted on‘Powderblue＇,with self-pollination as control,the fruit setting rate and fruit character,including fruit diameter,longitudinal diameter,single fruit weight and soluble solid content were investigated,so as to elucidate the effect of different pollination varieties on fruit setting rate and fruit characters,to provide knowledge for selecting pollination varieties of‘Powderblue＇.The results showed that there was significant difference in fruit setting rate,the fruit setting rate of cross-pollination was significantly higher than self-pollination,although the‘Powderblue＇with lower self-compatible.Simultaneously,there was significant difference in fruit character among the pollination combinations,the single fruit weight and soluble solid content of fruit of cross-pollination with‘Premier＇and‘Baldwin＇were significantly higher than cross-pollination with‘Tifblue＇and self-pollination of‘Powderblue＇.Therefore,the aforementioned results showed that the‘Premier＇and‘Baldwin＇were the best pollination varieties for‘Powderblue＇.
