| 摘 要： | 用石蜡切片法确定温州蜜柑花芽形态分化集中在3月初到4月中旬,同时用H2SO4—H2O2法分析了8年生和2年生树体秋春季叶片和茎矿质元素含量,结果表明:结果树茎叶钾含量最高,氮次之,磷和钙较低,花芽分化初期,氮和钾含量均有峰值.未结果树氮峰值较低,钾较高,且峰值时间较迟.用80%乙醇加热法和蒽酮硫酸比色法分析了醇溶性糖,淀粉和全糖含量,结果表明:结果树醇溶性糖含量花芽形态分化前积累其后下降,淀粉含量秋冬和早春较低,花萼原基后上升,总糖含量花芽形态分化前同醇溶性糖相似,形态分化期波动大.未结果树碳水化合物平均含量比结果树高,C/N比值比结果树高41.3%~63.3%.

| Abstract: | In order to understand the relationship between flower bud differentiation and nutrition in satsuma orange(Citrus unshiu Marc.) trees,the mineral elements and carbohydrate in the leaves and stems of bearing trees(8-year-old) and non-bearing trees(2-year-old) were measured from September to April.Flower bud differentiation occurred from early March to mid-April.In the leaves and stems of bearing trees K was the highest,followed by N,while P and Ca contents were comparatively low.At the early stage of flower ... |
