- Abstract
Scions of the non-ripening ruin and nor strains (Lycopersicum esculentum Mill) were grafted on normal understock plants (cv. Rutgers) in an effort to study the influence of roots and vegetative tissue on the ripening behavior of the tomato fruit. Reciprocal grafts of 'Rutgers' scions on rin and nor understocks as well as grafted controls were also established. No alteration in the ethylene, and CO2 evolution and color development of either mutant fruits on normal understock or of normal fruits on mutant understock occurred. We suggest that the inability of rin and nor mutant fruits to ripen normally stems either from the presence in mutant fruit of a non-translocatable ripening inhibitor, or from the absence of a non-translocateable ripening factor.
