The Effect of Shaking on Mung Bean Growth

Abstract (EN)

Much research has been conducted into the effects of mechanical stress on the growth of mature plants,1 however little research has been done on its effects on seedling growth. Here we subject mung bean seedlings to horizontal oscillation using an orbital shaker. The plants were grown for 10 days under continuous oscillation at rates ranging from 0 to 200 revolutions per minute (rpm). The results show that the oscillation has a significant effect on stem growth, with increasing oscillation rate correlated with reduced growth. Increased oscillation also reduced central root growth and increased side root curling, but had no effect on leaf size.
