IAA synergism and vitamin B1 antagonism with calcium for induction and growth of adventitious roots in branch cuttings of Dalbergia sissoo Roxb.
IAA induced adventitious roots in branch cuttings of D. sissoo, whereas vit. B1 promoted growth of these roots. A strong IAA synergism and vit. B1 antagonism with calcium was observed in induction and growth of adventitious roots. Treatments with IAA (571 microM) and calcium (134 microM) proved to be an ideal combination, exhibiting 87% rooting and 0.87 R/S ratio in branch cuttings, coupled with an increase of root length, root number, root fresh weight and root dry weight as compared to control.
