  • DESCRIPTION: Prohexadione-calcium is a plant growth regulator that inhibits gibberellin metabolism. It is frequently used as a growth-retardant compound for apples. Prohexidione-calcium is known to reduce terminal growth by inhibiting 2-oxoglutarate-dependent dioxygenases, which are involved in the formation of growth-specific gibberellins (e.g., the conversion of GA20 to GA1), a group of plant hormones that are primarily responsible for regulation of shoot elongation in apple trees. In addition, it is also known that prohexadione-calcium interferes with ethylene biosynthesis and flavonoid metabolism, which can influence other responses in the plant.
