摘  要:研究以柚类品种龙柚为材料,对发育过程中果皮、果肉总钙和可溶性Ca^(2+)含量及Ca^(2+)-ATPase活性进行了测定.结果表明:龙柚花前至花期子房总钙含量相对较低,花后有明显上升;龙柚果皮总钙和可溶性Ca^(2+)均在果实增大期保持持续增长的趋势,此时的果肉总钙呈明显下降趋势,而对应可溶性Ca^(2+)的变化幅度较大;龙柚Ca^(2+)-ATPase活性在花前较低,花期开始上升;而果皮和果肉的可溶性Ca^(2+)含量和Ca^(2+)-ATPase活性在增大期内均有一明显增长的过程或相对较高的水平.Change of total calcium, soluble Ca^2+ concentrations and Ca^2+-ATPase activity of ovary(fruitlet), rind and pulp of fruit Langyou Punnelo througlatout fruit development were investigated.The results showed:total Ca concentration in the ovary of Longyou Punnelo was at low level before and during full bloom,and significantly higher after flowering; During the stage of fruit enlargement,total Ca concentration continuously increase in the rind of fruit from Langyou Punnelo,but that of fruit pulp deceased,whereas soluble Ca^2+-ATPase activitiese in the find and pulp of the them showed markedly increasing trends or remained relatively hing levers during the period of fruit enlargement.
