Vitamins have been shown to prominently affect rooting of C. sativus hypo-cotyl cuttings. Among the various vitamins tested, ascorbic acid, L-phylloquinone, calciferol, riboflavin, thiamine mononitrate, cyanocobalamin, nicotinic acid and pyridoxine hydrochloride significantly promoted rooting in terms of earliness of root initiation and number of roots produced per cutting. The effects of vitamins were concentration dependant. Folic acid was found to be inhibitory to rooting, but its effects were not expressed in presence of other vitamins of the B complex groupf
