From: Nitric oxide is involved in the brassinolide-induced adventitious root development in cucumber
Effect of NO scavenger or inhibitors on BR-induced adventitious root formation. The primary root was removed from hypocotyls of 5-day-old germinated cucumber seedling. Explants were incubated in distilled water, 1 μM BR, 50 μM SNAP, 20 μM L-NAME, 100 μM Tungstate, and 200 μM c-PTIO for 5 days. Photographs were taken 5 days after treatment (a). Adventitious root length (b) and root numbers (c) were expressed as means ± SE (n = 10 explants from three independent experiment). Bars denoted by different letters were significantly different according to Duncan’s multiple test (P < 0.05)
