| 摘 要： | 对单性结实的‘国庆1 号’温州蜜柑和自花结实的‘华农本地早’橘从开花前子房发育至果实成熟采收期整个子房或幼果及果实的不同部位(果皮和果肉) 的钙与钾含量变化进行了测定。结果表明:1) ‘国庆1 号’花前及花期子房钙含量较高, 花后趋降; 而其钾含量在花前及花期相对较低, 花后上升;2) ‘华农本地早’花前子房钙含量相对较低, 花后有一上升过程; 而对应钾在花前及花期就已很高, 花后下降; 3) 两品种果肉的钙含量自花后65 d 后均呈下降趋势, 而‘国庆1 号’果皮的钙含量在花后80 d 有一显著上升, 对应的‘华农本地早’在花后125 d 才急剧增加, 之后直至果实成熟二者均维持在较高水平;4) 两品种果皮、果肉的钾含量在果实发育过程中均呈类似的下降趋势。

| Abstract: | Changes of calcium and potassium contents in the ovary or fruitlet and fruit different part (rind andpulp) from ovary development before full bloom to fruit maturation for harvest of citrus i1e. parthenocarpic ‘Guo-qing 1’(Citrus unshiu Marc. ) and self-pollinated ‘Huanong Bendizao’ ( C.reticulata Blanco) were investigated. The results showed as follows : 1) Calcium contents in the ovary (fruitlet) of ‘Guoqing 1’ (GQ1) were at high levels before and at full bloom , and then decreased. But its potassium contents were relatively low before and at full bloom , thereafter increased. 2) Calcium contents in‘Huanong Bendizao’ (HB) were at low levels before full bloom , and presented an increasing trend after full bloom. While its potassium contents were comparatively high before and at full bloom , and then declined. 3) Dynamics of calcium in the pulp of ‘GQ1’and‘HB’were all declining from 65 days after full bloom (DAFB) , while calcium content in rind of ‘GQ1’signifi2cantly rose at 80 DAFB , that of‘HB’sharply increased at 125 DAFB too , since then kept at high levels until maturation for harvest . 4) Potassium contents in rind and pulp in both of ‘GQ1’and ‘HB’were similarly declining during fruit development . |
