Effects of Gibberellic acid and Benzylaminopurine on Lateral Buds Induction of Figs cv. Black Genoa

Abstract

          A study of the effects of gibberellic acid and benzylaminopurine on lateral bud induction of Ficus carica L. cv. Black genoa was carried out in the Pomology greenhouse, Maejo University, Chiang Mai province from
July 2017 to August 2017. The objective was to determine the appropriate concentration of gibberellic acid and benzylaminopurine to induce lateral bud breaking in figs. The experiment was conducted as Completely Randomized Design (CRD) with 4 treatments 3 replications, and each replication consisted of 7 lateral buds.
The treatments were 1) tap water (control) 2) GA₄₊₇ 50 mg/l + BA 50 mg/l 3) GA₄₊₇ 150 mg/l + BA 150 mg/l and 4) GA₄₊₇ 250 mg/l + BA 250 mg/l treatments significantly induced lateral bud breaking faster than control as the breaking was completed within 20.33 and 12.67 days, respectively, while the buds in the control treatment took 39.66 days to complete breaking. Furthermore, the higher concentration treatments also provided higher percentages of bud breaking at 61.90% and 85.71%, respectively, compared to that of the control at 14.28%. Likewise, shoot length and leaf number from both treatments were also greater than those of the control.
