Abstract

Exogenously supplied nitrogenous bases in combination with IAA + sucrose hastened the formation of roots on hypocotyl cuttings of Phaseolus mungo L. cv. G31. While purine and pyrimidine bases had little effect when used alone, together with IAA or sucrose they increased the number of roots and the effect was even more pronounced in combination with (IAA + sucrose). By contrast, guanine inhibited rooting completely in higher concentrations even in combination with (IAA + sucrose), and cuttings died within 48–72 h.
