新红星苹果于1981年分别嫁接在M27 EMLA、P2/KA313、P22/KA313、C6/KA313砧上、栽植6年后,嫁接在P2/KA313和C6/KA313砧上的树体大小相似,并大于嫁接在M27 EMLA上,P2/KA313、P22/KA313砧诱发很多根蘖;相反,嫁接在M27 EMLA砧上无根蘖。1984年至1986年统计单株产量,P2/KA313和C6/KA313砧为最高,然而累计产量效应最大的是在M27 EMLA和P2/KA313砧,最小的是P22/KA313砧。叶片分析表明,M27 EMLA砧的叶N、Ca、Mn和Zn含量最高。
New apple trees were grafted onto M27 EMLA, P2 / KA313, P22 / KA313 and C6 / KA313 anvils respectively in 1981. After 6 years of planting, the trees grafted onto P2 / KA313 and C6 / KA313 anvils were similar in size and larger than Grafted onto M27 EMLA, P2 / KA313, P22 / KA313 anvils induced much tillering; on the contrary, grafting had no root tillers on the M27 EMLA anvil. From 1984 to 1986, the average single-plant yield of P2 / KA313 and C6 / KA313 anvils was the highest. However, the cumulative yield effects were the highest among the M27 EMLA and P2 / KA313 anvils and the smallest were the P22 / KA313 anvils. Leaf analysis showed that leaves of M27 EMLA had the highest N, Ca, Mn and Zn contents.
