在两个试验中，砧木对1年生容器栽‘美味’树的净光合作用(Pn)没有影响。在一次试验中，砧木对比叶重(SLW)的影响很小，在另一次试验中没有。砧木对新梢生长、叶片数、蒸腾速率(Tr)和暗呼吸(Rd)均无影响，均为一次性测定。这些数据不支持关于不同砧木上特定品种的Pn差异的报道。
There was no effect of rootstock on the net photosynthesis (Pn) of 1-year-old vegetative, containergrown ‘Delicious’ trees in 2 experiments. Rootstock effects on specific leaf weight (SLW) were slight in one experiment, and absent in another. There was no influence of rootstock on shoot growth, leaf number, transpiration rate (Tr) or dark respiration (Rd), each of which was determined in one experiment. These data fail to support reports of differences in Pn within a given cultivar on various rootstocks.
