摘要： 为明确不同的砧穗组合对苹果果实品质的影响,2010-2012年连续3年研究4种苹果砧木对红将军苹果果实品质和香气成分组成的影响。结果表明,不同砧木嫁接对果实品质和香气成分均有影响。其中以八棱海棠砧单果质量最大,以MM106单果质量最小;M26中间砧果实的硬度、Vc含量及可滴定酸含量等指标均为最高;M26自根砧木的果实可溶性固形物、可溶性糖含量最高,八棱海棠砧的最低;M26中间砧红将军的果实检测到的香气种类最多,M9自根砧果实中检测到的香气成分最低;以八棱海棠砧的红将军醇类和酯类含量最高,M9自根砧和M26自根砧红将军的酯类和醇类含量分别最低。

Abstract: To determine the effect of different rootstocks on fruit qualing of variety.The effects of rootstocks on fruit quality and aroma compound of Red General Fuji fruit on 4 different apple rootstocks were investigated consecutively from 2010 to 2012.The result showed that different rootstocks had different effects on the fruit quality and aroma components.Fruits on grafted on Malusp prunifolia (Willd.) Borkh possessed the largest fruit weight,whereas the fruit from the trees on MM106 had the smallest fruit weight.Trees on M26 interstock produced fruits with the biggest firmness,highest Vitamin C content and titratable acid.Fruits on Malusp prunifolia (Willd.) Borkh had the smallest firmness,lowest soluble solid,vitamin C,titratable acid and soluble sugar content.Fruits from the trees on M26 rootstock had highest soluble solid and soluble sugar content.The rootstocks had affected the kinds and the content of aroma compounds of Red General significantly.Fruits with the most kinds of aroma were from the trees on M26 interstock,whereas fruits from the trees on M9 rootstock had the least kinds of aroma.Fruits on Malusp prunifolia (Willd.) Borkh had the highest alcohols and esters content,however the fruits with lowest esters content were from the trees on M9 rootstocks and the fruits with the lowest alcohols were from M26 rootstocks respectively.
