Effects of Gibberellic acid on the development of Pachyrhizus ahipa (Wedd.) Parodi

Abstract : The effects of exogenous application of the growth regulator Gibberellic acid (GA3) were investigated on a determinate yam bean (Pachyrhizus ahipa) during long day conditions. GA3 daily applied to plants apical bud for 9 weeks, did not affect flowering and total dry matter production per plant. However dry matter partitionning was altered. The treatment resulted in enhanced aerial parts elongation growth relative to underground parts. GA3 principally caused an increase in shoot formation and internode length. The dry matter of stem increased at the detriment of the tuber and nodules one. The results showed that vines formation may be induced by GA3 in Pachyrhizus ahipa suggesting that the endogenous level of gibberellic acid could not be influenced by photoperiod as in Pachyrhizus erosus. The results also indicated that there is not necessarily a direct relation between endogenous plant gibberellic acid and flowering in P. ahipa.
