研究了普通安托诺夫卡苹果树未经处理的发育枝和结果枝叶片光合强度和产量。在个体发育过程中,短果枝叶丛和新梢叶片,由基部至顶部的光合强度变化是一致的,但果枝叶比发育枝叶衰老快、降低光合活性早。在低日照下光合作用中光辐射利用率和一天中高光照的 The photosynthetic intensity and yield of shoots and leaves of the untreated shoots and fruits of the ordinary Antonovka apple tree were studied. In the process of individual development, photosynthetic intensity changes from the basal to the top of the branches and shoots of the short fruit branches were consistent, but the foliage branches developed senescence faster than those of the branches and leaves, and the photosynthetic activity was earlier than the others. Photo radiation utilization in photosynthesis and high light during the day under low sunlight
