Abstract
The role of an auxin (1-naphthalene-acetic-acid, NAA) and a cytokinin (6-furfuryl-amino-purine, kinetin) in the response of the susceptible (Bonny Best, BB) and resistant (Nematex, Ntex) cultivars of tomato, to infection with Meloidogyne incognita was examined. NAA and kinetin in combination, but not separately, increased the susceptibility of the susceptible cultivar, as measured by the number of galls and degree of nematode development. When treated with a combination of NAA and kinetin the resistant cultivar produced galls but only a few larvae developed to maturity which shows that the resistance is not completely broken. It is suggested that plant growth hormones are not the only factors which determine the host response of tomato to M. incognita.
