摘　　要：研究结果表明,不同砧木对椪柑叶片净光合速率、叶绿素a及全氮含量有显著影响,且多呈现为椪柑/枳高于椪柑/椪柑和椪柑/福桔。在年周期或日周期中,半矮化枳砧椪柑的净光合速率多高于两种乔砧椪柑(p≤0.05)。不同砧穗组合的叶片C/N,在不同物候期中亦呈显著差异。相关分析结果表明,椪柑叶片的净光合速率与其产量呈极显著正相关;枳砧椪柑与两种乔砧椪柑间产量的差异,与其净光合速率的差异相一致。There are significant differences in the photosynthetic rate, total N and chlorophyll a content of 1eaves between Ponkan/ trifoliate orange and Po-nkan/Ponkan, Fonkan/Fuji. The photosynthetic rate of ponkan/trifoliate orange was significantly higher than that of the others during either the E-',seasonal variation or the diurnal variation, resulting in the significant difference in the total C and C/N value of the leaves in the former and the others during the different phenological phases. Results of correlation analysis show that the higher yield of Ponkan/trifoliate orange is responsible for its significantly higher photosynthetic rate than that of the other treatments.
