摘　　要：归纳了近年来有关园艺作物光合作用种质差异的研究成果,即木本园艺作物的光合速率低于草本作物,常绿树种低于落叶树种,彩叶植物低于绿叶植物;总结了光合性状的遗传表现及与之相关的光合色素、光合功能期等影响因素;并就当前园艺作物光合遗传研究中存在的问题进行了讨论,还就这一研究领域的前景进行了展望。The researches on germplasm differences of photosynthesis in horticultural crops were summarized. Generally, the net photosynthetic rate in the woody horticultural crops was lower than that in the herbaceous, that in the ever green tree species was lower than that in the deciduous ones, and that in colored-leaf plants was lower than that in green leaf ones. Moreover, some genetic expression of photosynthetic traits and affecting factors, such as photosynthetic pigments and function duration, were summarized. Lastly, some problems existing in researches on genetic law of photosynthetic traits and prospect in the research field were discussed.
