The Development of Heterodera Rostochiensis and Meloidogyne Incognita in Cross-Grafted Solanaceous Plants With Different Susceptibilities

The Development of Heterodera Rostochiensis and Meloidogyne Incognita in Cross-Grafted... THE DEVELOPMENT OF HETERODERA ROSTOCHIENSIS AND MELOIDOGYNE INCOGNITA IN CROSS-GRAFTED SOLANACEOUS PLANTS WITH DIFFERENT SUSCEPTIBILITIES *) BY A. RAE FORSTER (Rothamsted Experimental Station, Harpenden) It is known that plants within the same family may show marked differences in susceptibility to attack by the same nematode root- parasite. DONCASTER (1953) found that while Tomato (Lyco persicurn esculentum Mill.) was a host of Heterodera rostochiensis WOLT.., another Solanaceous plant, Black Nigthshade (Solanum nigrum L.), was only slightly susceptible to attack, no cysts being produced. Similarly Lycopersicum peruvianu1111 (L.) Mill. was found by TAYLOR & CHITWOOD (1951) to be resistant to Heloidogyne incognita (Kof. . & White, I9I9) Chitwood, 1949, while Tomato is a known host. It was thought that by cross-grafting resistant and susceptible plants together it might be possible to find out whether a resistant top would confer resistance on a susceptible rootstock, or whether a susceptible scion would cause a breakdown of the resistance of a rootstock on which it was grafted. During 1955 two experiments were carried out to investigate this possibility. In the first, larvae of H. rostochiensis were inoculated into the soil in which were growing cross-grafted plants of susceptible Tomato and resistant Solanum nigrum. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Nematologica Brill
