Conteúdo: | Experiments with tobacco (Nicotiana tabacum L., variety Wisconsin 38) tissue cultures showed that gibberellin, in concebntrrations which stimulated growth of callus, inhibited root and shoot formation. The effect on shoot formation was common to gibberellins A1, A3, A4, A5, A7, A8, and A9. Gibberellin did not prevent cell division completely, but retarded the differentiation of nodule-like structures, which evidently were forerunners of shoot primordia. Vascularization also remained uninhibited. The inhibitory effect upon shoot formation by 3 X 10-6 M GA3 lasted through two subcultures in gibberellin-free medium: recovery was complete in the third subculture.
