【摘要】 研究了6个柑桔优良品种（品系）叶片光合作用的能力及其适宜生态指标。结果表明,温州蜜柑叶片光合作用能力略大于甜橙;光补偿点和光饱和点(单位μmol·s^-1·m^-2,以下从略)为:国庆1号80～90和920～950,龟井65～75和780～820,尾张50～60和650～700,脐橙70～80和930～950,锦橙60～70和720～760,夏橙40～45和610～640;利用光合有效辐射的能力是国庆1号、脐橙>龟井>锦橙>尾张>夏橙,耐荫性和在低水平光照下进行光合作用的能力等规律则相反;适宜的叶片温度指标是国庆1号、龟井和锦橙25～30℃,尾张约25℃、脐橙和夏橙25～35℃;土壤相对持水率适宜指标为60％～80％。以上指标为柑桔良种适地适栽提供了科学依据。更多还原

【Abstract】 Six major citrus superior cuitivars wore investigated for main optimum ecological indexes of leaf photosynthesis. Their light compensation point and light saturation point of leaf photosynthesis were as follows (units are all μmol·s^-1·m^-2, omitted here.): Guoqin No. 130～90 and 920～950, Kamei 65～75 and 780～820, Owari 50～60 and 650～700, Bonanza navel 70～80 and 930～950, Jincheng 60～70 and 720～760, and Cutter valencia 40～45 and 610～640. Their optimum leaf temperature of photosynthesis was as follows: Guoqin No. 1, Kamei and Jinchong 25～30℃, Owari about 25℃, Bonanza navel and Cutter valencia 25～35℃. The optimum index of soil relative moisture percentage varied from 60% to 80%.更多还原
