摘要
The tomato (Solanum lycopersicum L.) slender mutant procera (pro)) was analysed for its relationship with gibberellin (GA) by combining it with GA deficiency due to the gib-1 mutation, The sensitivity to GA biosynthesis inhibitors and the GA content were measured in the pro gib-1 double mutant. In the gib-1 mutant background, the pro mutation strongly reduced the GA requirement for seed germination and stem growth and almost fully restored the morphological leaf defects of the gib-1 mutant. An end-of-day far-red light treatment, when applied to the various genotypes, indicated that GAs are required for a response to this treatment, but that it act independently of the Pro gene product.
