Flurprimidol

Flurprimidol, also known as fluoropyrimidine, is a nitrogen-containing heterocyclic growth retardant. It is a substitute for Ancymidol, and its activity is 2-4 times higher and more stable than Ancymidol. Furimol inhibits the biosynthesis of gibberellin by suppressing cytochrome P450 dependent monooxygenase (a type of enzyme that catalyzes the oxidation of kaempferol to kaempferol), leading to inhibition of internode elongation. Furimol not only delays plant growth, but also helps improve bulb formation. There are literature reports that treatment with furosemide (10 μ M) increases bulb formation in scallion bulbs, but has no effect on differentiation degree. Furimol can also be used as a growth regulator for green grass.
