GA3 dissolved in 0.2% ethanol inhibited the adventitious root formation in mungbean cuttings. Conversely, when it is dissolved in water, GA3 promoted the adventitious rooting response at 10-7 and 10-8 M concentrations. Ethanol suppressed the promoting effects of GA3. Generally, it has been observed that low concentration of GA3, favour rooting and high concentration inhibit it. Furthermore no evidence of synergism between supplied GA3 and IAA was observed. Kinetin, at low concentration and in the presence of IAA promoted rooting response. ABA at 10-5 M and in the presence of IAA promoted adventitious root formation. The stimulatory effects of ABA was more pronounced at 5x10-4 concentration of ABA.
