Abstract

Sub-terminal stem cuttings of two winged bean genotypes, PI 413214 and PI 413216 were treated with three levels of indolebutyric acid (IBA) and sampled after 15, 17, 19 and 23 days to examine rooting response. IBA treatment dramatically increased root dry weight, root length and root number in PI 413214 over time but had little effect on PI 413216. However, root characters had generally high values and rooting was faster in the latter at all IBA levels. Increases in root dry matter of the untreated cuttings appeared to be linear with time for both genotypes but their corresponding slopes at the three IBA concentrations were highly significantly different.
