Mepiquat chloride; CAS NO 24307-26-4; plant growth regulator used to reduce vegetative growth including sprout suppression in onions, leeks and garlic

Mepiquat chloride has a delaying effect on the vegetative growth of plants. Mepiquat chloride can be absorbed through the leaves and roots of the plant and transmitted to the whole plant. It can reduce the activity of gibberellin in the plant, thereby inhibiting cell elongation, weakening the growth of terminal buds, and controlling the plant Vertical and horizontal growth shortens the internodes of the plant, compact plant type, deep leaf color, reduced leaf area, and enhances the synthesis of chlorophyll, which can prevent the plant from growing prosperously and delay the closure. Mepiquat chloride can improve the stability of cell membranes and increase plant resistance to stress.
