A field experiment was conducted using Hanfu apple grafted on 10 dwarfing interstocks to evaluate plant growth, yield, and fruit quality of different apple-interstock combinations in Hulu-dao, Liaoning Province, in order to select the most suitable apple-interstock combinations in the study area. The results showed that tree vigor, yield, and fruit quality were largely affected by the interstocks. Among the interstocks evaluated here, plant height, branch numbers, leaf fresh weight, branch fresh weight, root fresh weight, total root volume, average root diameter and total root tip numbers were the largest on GM256, while the highest trunk diameter, branch length, total root length and total root surface area were observed on CX5, the highest fruit firmness, soluble solids and soluble sugar contents were observed on M26, and the highest fruit vertical diameter, transverse diameter and single fruit weight were observed on GM256. The fuzzy evaluation results showed that the comprehensive character scores decreased in order of GM256, CX5, B9, JM7, CG80, Liaozhen 2, M26, Qingzhen 3, SH38 and MD001. Our results indicated that interstock GM256 and CX5 was better for the cold climate region.
在辽宁省葫芦岛市，以10种矮化中间砧嫁接寒富苹果进行田间试验，以评估不同苹果中间砧组合的植株生长、产量和果实品质，从而筛选出研究区域最适宜的苹果中间砧组合。结果表明，中间砧对树势、产量和果实品质有很大影响。在所评估的中间砧中，GM256的株高、枝量、叶鲜重、枝鲜重、根鲜重、总根体积、平均根径和总根尖数最大，CX5的干径、枝长、总根长和总根表面积最高，M26的果实硬度、可溶性固形物和可溶性糖含量最高，GM256的果实纵径、横径和单果重最大。模糊评价结果表明，综合性状得分由高到低依次为GM256、CX5、B9、JM7、CG80、辽砧2号、M26、青砧3号、SH38和MD001。我们的结果表明，中间砧GM256和CX5更适合寒冷气候地区。
