Germination of Peanut Seeds (Arachis hypogaea L.) with different doses of Gibberellin

Abstract

Objective: Evaluate the germination of peanut (Arachis hypogaea L.) by using different doses of gibberellic acid (GA3). Design / methodology / approach: A completely random design was use. Three treatments with 20 repetitions were use. Treatment 1: 0.05gr/L of gibberellic acid (GA3), Treatment 2: 0.10gr/L of gibberellic acid (GA3), Treatment 3: 0.15gr/L of gibberellic acid (GA3) and Treatment 0: Witness. Peanut seeds of the Virginia variety were use. The parameters to be evaluate were seedling height, number of leaves, root measure and biomass. The means were compare by the Tukey test at a level of 5% confidence.Results: The treatments indicated that Treatment 0 (Witness) obtained a percentage of germination of 85%, being higher than treatment 3 (0.15gr/L of GA3) with 75% germination, however, treatment 1 (0.05gr/L of GA3) and 2 (0.10gr/L of GA3) presented a better response when obtaining 95% of germination each.Study limitations / implications: Treatment 3 causes negative effects on the germination of the plant.Findings / conclusions: It is necessary to follow up the research for a better control of the environment and to increase the doses of GA3, as well as to increase the speed of germination by applying 0.15gr / L of GA3.
