摘要
研究发现在11月休眠期去除贮藏根的红球姜次年不会开花,4月萌芽后去除贮藏根的花少,且花枝短;宿根带贮藏根的红球姜花多,花枝长.贮藏根淀粉含量随红球姜的萌芽而逐渐降低;根茎的淀粉含量在萌芽前后变化不大.萌芽初期贮藏根的可溶性糖含量比萌芽前提高了63 6%,越接近花期,可溶性糖含量越高;根茎的可溶性糖含量先升后降,萌芽初期可溶性糖含量比萌芽前提高了43 5%,萌芽后可溶性糖含量有所下降.
The present research indicated that, the storage root of Zingiber zerumbet were removed in November, the seedling would not flower next year; if removed in April, there would be few flowers and the stalks would be shorter. There was some transfer of starch and soluble sugar from storage root to rhizome:with the development of shoots, the starch content in storage root decreased but that of soluble sugar increased; however no apparent change in starch content was found in the rhizome, which at the early phase of sprouting showed increase in soluble sugar but decrease on later.
