| 以瑞香红/G935、爱妃/G935、瑞香红/M26和爱妃/M26四个砧穗组合为研究对象，通过对苹果树生长发育、果实品质等相关指标进行测定，研究了苹果树不同砧木抗重茬的能力。结果表明，在栽培管理同等条件下，同品种间比较，用G935作砧木，苹果树的树高、干径、主枝数、单果重、果实硬度等生长发育和果实品质相关12个指标值均高于用M26作砧木；而不同品种间比较，瑞香红组合的生长发育、果实品质相关指标值分别优于爱妃组合；隶属函数分析表明四种砧穗组合抗重茬能力大小为：瑞香红/G935>爱妃/G935>瑞香红/M26>爱妃/M26，以上综合说明矮化自根砧G935的抗重茬能力优于矮化自根砧M26，因此，在克服重茬栽培问题上，矮化自根砧G935可以作为抗性砧木进行进一步培养。 |
| 英文摘要: |
| Four scion/rootstock combinations—Ruixiang Hong/G935, Aifei/G935, Ruixiang Hong/M26, and Aifei/M26—were evaluated to assess the resistance of different apple rootstocks to replanting stress. Parameters related to growth, development, fruit quality, and other relevant indices were measured. The results showed that, under identical cultivation and management conditions, 12 indices related to growth, development, and fruit quality were consistently higher in apple trees grafted onto G935 than in those grafted onto M26. Moreover, the indices associated with growth and fruit quality were generally superior in the Ruixiang Hong combinations than those in the Aifei combinations. Membership function analysis indicated that resistance to replanting followed the order: Ruixiang Hong/G935 > Aifei/G935 > Ruixiang Hong/M26 > Aifei/M26. Overall, the dwarf self rooted rootstock G935 exhibites stronger resistance to replanting stress than M26 and may be considered a promising rootstock for alleviating apple replanting issues. |
