| 摘 要： | 观察了毛棉杜鹃(Rhododendron moulmainense Hook.f.)花芽和叶芽分化过程,测定了花芽分化各时期花芽和叶芽封顶叶的总糖、总氮、可溶性蛋白和磷的质量分数,探讨了C、N、P等营养物质与毛棉杜鹃花芽分化的关系.结果表明,在整个花芽分化期,花芽封顶叶的总糖和磷质量分数明显高于叶芽封顶叶,而且其质量分数呈上升趋势;而总氮则相反;花芽和叶芽封顶叶的可溶性蛋白质量分数的变化趋势比较接近,但质量分数则是花芽封顶叶的高,并且在分化的 |

| Abstract: | A study was conducted to determine the contents of total sugar,total nitrogen,soluble protein,and phosphorus of the leaves under flower buds and leaf buds at different stages of flower bud differentiation based on the observation of differentiation process of flower buds and leaf buds of Rhododendron moulmainense Hook.f.The relationships between the nutrients(C,N,P)and flower bud differentiation were discussed.Results indicated that,during the process of flower bud differentiation,the contents of total suga... |
