| 以富平秋子为基砧，B9等7种苹果矮化砧木、M26（CK）作中间砧嫁接秋富1品种，在陕西渭北地区建园进行比较试验。8年观察、测定结果表明，B9和SX13的树高分别相当于M26的66.5%，80.7%，树冠体积相当于M26的53.6%和67.5%，冠径相当于M26的89.2%和94.4%，累计产量分别比M26高13%和28%以上；Mark树高小于M26，树冠体积、冠径较M26大，累计产量比M26高7.1%；77-34的树高与M26相当，树冠体积、冠径相当于M26的135.9%和116.3%，累计产量相当于M26的133.8%；CG24,EMLA9和75-9-5树高小于M26，树冠体积、冠径均大于M26，累计产量相当于M26的50.6%～78.7%。各试验砧系组合的果实品质优于或与M26相当。B9,Mark,SX13,77-34综合性状优良，可在渭北及条件相似的黄土高原苹果产区推广应用。 |

| Abstract: |
| The experiment orchard was set up in Weibei area,Shaanxi Province,with Akita Fuji 1 grafted onto inter-rootstock of different clones and M26 (CK),M.prunifolia Borkh as base-rootstock.8-year experiment result showed that tree heights of B9 and SX13 were 66.5% and 80.7% of M26,canopy volumes were 53.6% and 67.5% of M26,canopy diameters were 89.2% and 94.4% of M26，accumulative yields was 13% and 28% higher than that of M26 respectively.With tree height lowering,canopy volume and canopy diameter were larger than those of M26,accumulative yield of Mark was 7.1% higher than that of M26.Tree height of 77-34 was similar to that of M26,canopy volume and canopy diameter was 135.9% and 116.3% of M26 respectively,accumulative yield was 133.8% of M26.CG24,EMLA9 and 75-9-35 had lower tree height,bigger canopy volumes and canopy diameters,with yield equal to 50.6%-78.7% of M26.Fruit quality of the stock clones was better or equal to M26.B9,Mark,SX13,77-34 with better integrated traits,could be used in Weibei apple growing area. |
