[11]Functional features

Cyclopentadiene lactone is the general name of some natural cyclopentadienol compounds and synthetic analogs. It belongs to sesquiterpene compounds with isoprenoid as the basic unit. It is a carotenoid derivative produced in plant roots. It can inhibit the growth of branches and lateral buds of plants, maintain the plant type together with auxin and cytokinin, and coordinate the growth of aboveground and underground parts of plants.

[12]Applied Technology

Non-heading Chinese cabbage

When nonheading Chinese cabbage grows 11~12 true leaves and some axillary buds begin to grow, adding 0.45~1.35mg/L solution to the nutrient solution for 3~12h can directly inhibit the germination and elongation of axillary buds, and can also indirectly inhibit the germination and elongation of axillary buds by regulating the signals related to endogenous auxin and cytokinin and the expression of genes related to tillering or branching.

Red seedling

When a bunch of red seedlings grow two pairs of true leaves (lateral buds have germinated), apply 0.3~9mg/L of liquid medicine to the lateral buds at the axillary buds of the first to third sections of the plant stem nodes, which can promote the plant height and internode length of the crop, and the higher the concentration, the more obvious the promotion effect, and the inhibition effect on the elongation of lateral branches. The higher the concentration, the more obvious the inhibition effect.

[13]Precautions

①It is easy to degrade in alkaline soil, and it is also easy to be lost under the influence of microorganisms.

②The effect of monopodial lactone is related to crop varieties.
