Product Features:
Prohexadione calcium mimics the structure of 2-oxoglutarate, competitively inhibiting the activity of hydroxylases, thereby inhibiting the synthesis of active gibberellins. Among the hydroxylation reactions in gibberellic acid biosynthesis in plants, the 13-hydroxylation and 3-β-hydroxylation reactions in the GA1 pathway are most sensitive to prohexadione calcium. The 13-hydroxylation reaction is not involved in the GA4 and GA7 pathways. Therefore, prohexadione calcium selectively inhibits the biosynthesis of gibberellins GA1, making it an ideal dwarfing agent.
Prohexadione calcium is a novel plant growth retardant and a late-stage inhibitor of gibberellin biosynthesis. It has low toxicity, no residual residue, and no adverse effects on subsequent crops or the environment.
It inhibits GA1 biosynthesis, controls vegetative growth, and promotes reproductive growth. It can protect existing gibberellin GA4 activity, effectively preventing premature aging in crops. It also exhibits a certain degree of stress resistance, combining growth control, yield increase, and disease prevention.
