摘要
以16种西瓜砧木为试材,采用聚类分析和隶属函数分析方法,研究了南方根结线虫(Meloidogyne incognita)对不同砧木的生长指标和抗病指标的影响。结果表明:抗性最强的是"青农2号",隶属函数总值为6.26,抗性最弱的是"青农3号",隶属函数总值为1.48。结论认为"青农2号"为西瓜嫁接的最佳砧木,该试验为合理筛选和利用西瓜砧木提供了理论和技术参考。
The growth indexes and disease indexes of 16 watermelon rootstocks which were planted in pots and inoculated with Meloidogyne incognita were measured in the experiment,and the clustering analysis and subordinate function analysis were conducted.The results showed that ‘Qingnong 2＇with the subordinate function value 6.26 had the strongest resistance capacity,while‘Qingnong 3＇with the subordinate function value 1.48 had the lowest resistance capacity.The conclusion was that the best rootstock for watermelon grafting was‘Qingnong 2＇.It provided theoretical and technical reference for rational selection and utilization of watermelon rootstocks.
