Abstract:
Fruits of the two non‐ripening mutants of tomato, rin and especially nor, were markedly more resistant to Rhizopus stolonifer infection than the normal Rutgers fruit. Following artificial inoculations by contact with a diseased normal tomato covered with mycelium and sporangia, no infection of unwounded nor fruit occurred at its mature‐green stage. At the mature stage the resistance of nor mutant fruit was manifested by a prolongation of the incubation period of the disease as well as by a markedly reduced incidence of rotted fruits. Chilling injury of fruit, prior to spore inoculation, was found to be a good means for indicating the relative resistance of the mutants as compared with the normal tomato. The relationship between the resistance of the mutant tomatoes to Rhizopus infection and their response to induced peel damage as a result of the contact or the chilling procedure, led to the assumption that fruit resistance is associated with the inability of the fungus to penetrate the periderm, rather than with fungal development within the fruit.
