Potential regulatory role of gibberellic and humic acids in sprouting of Chlorophytum borivilianum tubers

Tubers of safed musli (Chlorophytum borivilianum) were immersed in three different concentrations of gibberellic acid (GA3) or humic acid (HA) prior to planting. The highest concentration of GA3 (20 mg  ) and all concentrations of HA (5, 10, and 15%) appeared to hasten tuber sprouting and promote un...
