在大棚条件下，研究了两株“美味”株系集装箱苹果树幼树的生长性能。第一季在苗木砧木上种植红刺鲜（Redspur Delicious）和Richared Delicious，第二年在苗木、MM 106和M VII-A砧木上种植。红刺叶的净光合作用（Pn）倾向于高于赤褐色叶的Pn。一个季节的数据表明，温室树木在幼苗砧木上的Pn叶片高于mm106。M VII-A上的树木叶片Pn含量处于中间水平。呼吸速率不受菌种和砧木的影响。标准鲜木比直型强，表现为茎长、节间长、叶数和总叶面积大。然而，马刺型树木有更大的树皮-木材比。砧木对叶片大小和干叶重均有影响，但菌株对叶片大小和干叶重没有影响。4张图，2张表。
The performance of young container grown apple trees of two Delicious strains was studied under greenhouse conditions in a 2 year experiment. Redspur Delicious, a spur type strain, and Richared Delicious were grown on seedling rootstocks in the first season and on seedling, MM 106, and M VII-A rootstocks the following year. Net photosynthesis (Pn) of Redspur leaves tended to be higher than the Pn of Richared leaves. One season's data indicated that the Pn leaves of greenhouse grown trees on seedling rootstocks was higher than those on MM 106. Leaves of trees on M VII-A were intermediate in Pn. The respiration rates were not affected by strains or rootstocks. Standard Delicious trees were more vigorous than trees of the spur type as indicated by greater shoot length, internode length, leaf number and total leaf area. The spur type trees had, however, a greater bark-wood ratio. Rootstocks affected both leaf size and dry leaf weight, but strains did not. 4 figures, 2 tables.
