Abstract:
In order to screen melon rootstocks resistant to Fusarium wilt,inoculation experiments of different rootstocks at seedling stage were carried out,and the comprehensive characters of compatibility,yield and quality of grafted seedlings of different rootstocks were studied.The resistance of 4 rootstock pumpkin materials to NX-1,NX-2,NX-3 and NX-4 were tested by seedling inoculation method.The survival rate,field incidence rate,single fruit weight,yield,soluble solid content and taste of grafted seedlings were observed and measured.The results showed that Nx-2 and Nx-3 were highly resistant to Fusarium wilt at seedling stage,while Nx-1 and Nx-4 were resistant to Fusarium wilt.Muskmelon and scion were highly compatible with 4 rootstocks,and the survival rate of grafted seedlings was higher than 95%.The disease resistance and disease incidence rate were significantly lower in the field than in the control(Guangmi No.1 striffen muskmelo seedlings).Except Nx-2,the content of central soluble solid and taste of the other treatments were close to the control,and the performance was better.Among the four rootstocks tested,Nx-3,Nx-1 and Nx-4 had excellent comprehensive characters and were ideal rootstocks for striffen muskmelon grafting.
