From: Nitric oxide is involved in the brassinolide-induced adventitious root development in cucumber
Effect of different concentrations of BR on the average root length and the average root number of cucumber adventitious roots development. Photographs were taken after 5 days of treatment. The different concentration of BR adventitious root length (a) and root numbers (b) were expressed as means ± SE (n = 10 explants from three independent experiments). Bars denoted by different letters were significantly different according to Duncan’s multiple test (P < 0.05)
