杨梅的成熟季节高度集中,果实很不耐贮藏,使得供应期十分短促。但杨梅果实对生长调节剂和化学物质反应敏感,本试验所使用的几种生长调节剂和化学物质对杨梅成熟期都有影响。其中以喷布乙烯利促使果实早熟和喷布阿拉延缓果实成熟的效果最好。在果核硬化以后喷布250ppm乙烯利,可使杨梅提早6～8天成熟;在果核硬化前喷布2000ppm阿拉,可使杨梅延迟5～6天成熟,并能保持果实原有品质,且使次年开花和产量增加。因此有希望利用乙烯利和阿拉来延长杨梅供应期。
The ripening season of bayberry is highly concentrated, and the fruit is very resistant to storage, which makes the supply period very short. However, the fruit of Myrica rubra is sensitive to growth regulators and chemical substances. Several growth regulators and chemicals used in this experiment have an impact on the ripening stage of Chinese bayberry. Among them, spraying ethylene to promote fruit ripening and spraying Allamanda fruit ripening the best. Spraying 250ppm ethephon after nucleus sclerosis can make bayberry mature 6 to 8 days earlier; spraying 2000ppm aloe before nucleus hardening could delay arborvitae ripening for 5 ~ 6 days and maintain the original quality of the fruit, and The next year flowering and production increased. So there is hope to use ethephon and Allah to extend the supply of bayberry.
