Abstract
Utilization of synthetic benzyladenine (BA) for bean sprout production should be reduced or minimized because of elevating production cost and not ascertaining action mechanism to human body. The study was done to compare the effects of BA concentrations under different watering methods (overspraying or underwatering) on growth and morphological characteristics of mungbean sprouts. Seeds of cv. Zhong-Lu 1 were soaked for 5 hours in the solutions with different BA concentrations (0, 10, 20, 30, 40, 50 ppm) before 4 hour aeration, and then were cultured for 6 days by both watering systems. Their morphological characters, fresh and dry weights were measured. Regardless of watering methods, lateral roots were sharply dropped over 30 ppm BA concentrations, and hypocotyl, root and total lengths were shortened with increased BA concentrations although ratios of hypocotyl to root lengths and hypocotyl diameters were enlarged with their increment. Total fresh weights were increased up to 20 ppm in overspraying method but up to 30 ppm in underwatering method mainly due to increment of hypocotyl fresh weights. The sprouts were faster grown in overspraying method than in underwatering method because the former showed longer lengths of hypocotyl and root, and total fresh weights.
