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.
