Abstract
ABSTRACT Soaking seeds in gibberellic acid can alter seedling performance by directly affecting reserve mobilization and the formation of vigorous seedlings. The aim of this study was to assess whether common bean seeds with contrasting vigor pre-soaked in different doses of exogenous gibberellic acid (GA3) exhibited changes in reserve mobilization and seedling development. The experimental design was completely randomized, with a 2 x 5 factorial scheme (two cultivars and five GA3 concentrations). The BAF55 and BAF44 cultivars were characterized as high and low vigor, respectively. The parameters assessed exhibited cultivar-dose interaction, demonstrating genetic variability for sensitivity to the hormone. An increase in GA3 doses compromised reserve mobilization in BAF55, with the larger amount of remaining dry mass in the cotyledons indicating that the reserves were not used during seedling development, resulting in lower dry mass. On the other hand, higher hormone doses favored seed reserve use, promoting greater seedling length. GA3 doses up to 0.10 mM L-1 resulted in greater hypocotyl, epicotyl and seedling length and lower cotyledon mass, demonstrating use of the energy reserves previously synthesized in the cotyledon. Thus, while applying the hormone to seeds directly influences seedling architecture, it promotes more efficient use of cotyledon reserves in cultivar BAF44, producing taller, more vigorous seedlings with higher dry mass.
