Effect of R. pallidifolium on the growth of cress. R. pallidifolium was transplanted onto agar mS medium and grown at 25°C with a 12-h photoperiod for 5 days as described previously.9 Cress seeds was then placed on the medium (A) and incubated at 25°C with a 12-h photoperiod for 2 days (B). The length of cress hypocootyls and roots was mesured and inhibition % was deterined by the formula: [(control plant length - plant length incubated with R. pallidifolium)/control plant length] × 100. Control cress was incubated on the medium in the absence of R. pallidifolium (C). Different letters indicate significant differences (p < 0.05) according to Tukey's test.
