In vitro germination of beetroot seeds treated with Ga3 and sucrose

Abstract

The objective of this study was to evaluate the in vitro germination of beetroot seeds, cv. Early Wonder Tall Top, treated with gibberellic acid and sucrose at different concentrations. A randomized complete block design in a 2 x 5 factorial arrangement with five replications was used. The beetroot seeds ware pre-soaked in gibberellic acid (GA₃) and destilated water during six hours, maintained of five concentration of culture medium (0, 15, 30, 45, 60 g L^-1). Seeds treated with GA₃ and maintained in medium with sucrose in the concentrations of 15 g L^-1 presented the highest germination, while seedlings with the highest vigor were obtained with seeds maintained in the medium at 15 and 30 g L^-1 of saccharose.
