The gibberellins (GA) present an essential role in many aspects of plant development, seed germination, internode elongation, flower and fruit development. Thus, this work aimed to evaluate the growth attributes and the physiological quality of bean seeds from plants submitted to the application of gibberellic acid, revealing great importance in some characters of agronomic interest. Seeds of genotypes (Phaseulus vulgaris) Mouro and BRS Embaixador and four concentrations of gibberellic acid (zero, 50, 100 and 200 mg L) were used. Seed germination, first count, germination speed, primary root and shoot length, dry matter of seedlings, shoot height, stem diameter, first pod insertion, pod number and seeds per pod were evaluated. Giberelic acid promoted an increase in plant height and a reduction in stem diameter. Seeds produced under doses of GA3 did not influence seed germination and dry matter of the seedlings at higher doses, being dependent on the cultivar. In this way, the application of increasing doses of GA3 in bean plants increases the height of insertion of the first pod, while the physiological quality of the seeds produced is affected by the acid doses.

Attributes of growth, physiological quality and isoenzymatic expression of common bean seeds produced under the effect of gibberellic acid
