摘要
以13种西瓜砧木为试验材料,运用聚类分析和隶属函数两种方法分析,开展西瓜砧木被南方根结线虫侵染后,其对生长指标和抗病指标影响试验。结果表明:抗性最强的是‘京欣砧王’,隶属函数总值为5.70,抗性最弱的是‘勇士’,隶属函数总值为3.50。说明‘京欣砧王’为西瓜嫁接的最佳砧木。
Growth and disease-resistance of 13 watermelon rootstocks were analyzed using cluster analysis and subordinate function index.The rootstocks artificially infected by Meloidogyne incognita were planted in pots for the experimentation.The results showed the variety,Jingxinzhenwang,to be the strongest in resisting the disease with a subordinate function index score of 5.70,and Yongshi the weakest with a score of 3.50.The information would be critical for selecting and utilizing appropriate watermelon rootstocks.
