摘　　要：为筛选核桃不同中间砧木适宜的嫁接品种,采用在贵州种植以后适应性差需要高接换优的品种云新和漾濞作为中间砧,以贵州现有的优良品种黔林核5号、黔林核1号和雪凝红为接穗,分析不同中间砧木砧穗组合芽接后成活率、长势及生理特性和嫁接亲和性的关系,测定嫁接后不同中间砧木组合新稍叶片的可溶性糖、可溶性蛋白、可溶性淀粉、多酚氧化酶(PPO)和过氧化物酶(POD)活性,并统计嫁接后的新枝生长量及成活率。结果表明,无中间砧木组合的成活率和长势都显著高于有中间砧木的组合;POD和PPO含量在黔林核5号和雪凝红砧穗组合中无显著差异,黔林核1号有显著差异。不同中间砧木对黔林核5号和黔林核1号组合新稍叶片中的可溶性糖含量差异显著,对雪凝红组合差异不显著。不同中间砧木对黔林核5号、雪凝红和黔林核1号组合的可溶性淀粉和可溶性蛋白都有显著差异。本研究用隶属函数法对核桃不同种中间砧木砧穗组合嫁接亲和性进行综合评价,得出无中间砧木组合的亲和性大于有中间砧木的组合,中间砧木云新和漾濞适合高接换优的最优品种为黔林核1号。In order to select suitable grafts for different intermediate rootstocks of walnut,Yunxin and Yangbi,which have poor adaptability and need high grafting after planting in Guizhou,were used as intermediate anvils,and the existing excellent varieties Qianlinhe 5,Qianlinhe 1 and Xueninghong in Guizhou were used as suds to analyze the relationship between survival rate,growth,physiological characteristics and grafting compatibility of different intermediate rootstocks.The activities of soluble sugar,soluble protein,soluble starch,polyphenol oxidase(PPO)and peroxidase(POD)in the leaves of different intermediate rootstock combinations were measured,and the growth and survival rate of new shoots after grafting were measured.The results showed that the survival rate and growth rate of the group without intermediate rootstock were significantly higher than those with intermediate rootstock.There was no significant difference in POD and PPO content between Qianlinhe and Xueninghong,but there was significant difference between Qianlinhe 1.The difference of soluble sugar content in leaves of Qianlinhe and Qianlinhe 1 among different intermediate rootstocks was significant,but not significant for Xueninghong combination.The soluble starch and soluble protein of Qianlinhe 5,Xueninghong and Qianlinhe 1 were significantly different in different intermediate rootstocks.In this study,the graft compatibility of middle rootstock combinations was evaluated by membership function method.The compatibility of middle rootstock combinations without middle rootstock was higher than that of middle rootstock combinations with middle rootstock.Yunxin and Yangbi were the best varieties suitable for high grafting.
