摘要
以29份南瓜材料为砧木,以西瓜品种美秀为接穗,对不同嫁接组合愈合期和共生期的16项指标进行统计分析,并通过基于PCA的隶属函数分析法和聚类分析法对参试砧木进行综合评价和筛选。结果表明:综合比较嫁接后6 d的不萎蔫率和品红含量,9份砧木材料的愈合期嫁接亲和力较强,分别为ZM4、ZM7、ZM10、ZM11、ZM13、ZM17、ZM22、ZM25、ZM27。通过对30个嫁接组合愈合期和共生期16项指标的综合评价,筛选出3份亲和力较强的砧木材料:ZM17、ZM11、ZM22,可作为砧木育种新材料。
Using 29 pumpkin materials as rootstocks and‘Meixiu’as scion,we statistically analyzed 16 traits of different grafting combinations in the healing and symbiosis stages,and screened and classified the rootstocks by membership function analysis based on PCA and cluster analysis.The results indicated that by comparing the two traits of non-wilting rate and fuchsin content at 6 days after grafting,the healing compatibility of 9 rootstocks was stronger,which were ZM4,ZM7,ZM10,ZM11,ZM13,ZM17,ZM22,ZM25 and ZM27.Through the comprehensive evaluation of various traits in the healing and symbiosis stages of different grafting combinations,it was found that the D values of the three materials were high,which were ZM17,ZM11 and ZM22,and could be used as new stock breeding materials.
