红富士苹果自花座果率很低,与授粉品种花期是否一致,直接影响其产量和质量。据观察,红富士苹果的花期一般比授粉品种(新红星、金帅等品种)晚2～3天。但1995年的花期却比授粉品种提前了2～3天,这一反常的现象引起了广大果农和果树工作者的疑虑。 Red Fuji apple self-inflorescence fruit rate is very low, and the flowering of the same species of pollination, a direct impact on their yield and quality. It is observed that the flowering of red Fuji apples generally than pollination varieties (New Red Star, Jin Shuai and other varieties) 2 to 3 days later. However, the flowering period of 1995 was 2 to 3 days earlier than that of the pollination species. This anomaly has aroused the suspicion of the majority of fruit growers and fruit tree workers.
