Fig. 1From: Nitric oxide is involved in hydrogen gas-induced cell cycle activation during adventitious root formation in cucumberEffect of different concentrations of HRW on the induction of adventitious root development in cucumber explants. The primary root system was removed from hypocotyls of 5-day-old germinated cucumber. Explants were incubated with distilled water or different concentrations of HRWas indicated for 5 days. Adventitious root numbers (a) and length (b) were expressed as mean ± SE (n = 3) 10 explants was used in an independent experiment. Bars not sharing the same letters were significantly different by Duncan’s test (P < 0.05)Back to article page
