Plant growth inhibitors are plant growth inhibitors that inhibit the growth of apical meristem and make plants lose their apical advantage. There are many side branches and small leaves, and the reproductive organs are also affected.

Natural plant growth inhibitors include abscisic acid, cinnamic acid, coumarin and salicylic acid.

There are two kinds of artificial synthesis: triiodobenzoic acid and maleic hydrazide.

Several common plant growth inhibitors;

1.7 TIBA(2. 3. 5- triiodobenzoic acid)?

TIBA is an anti-auxin regulator, which can hinder the transport of auxin and gibberellin in phloem. Its structure is similar to auxin, and it can compete with auxin for action sites, so that auxin can not bind to its receptor, so it is a competitive inhibitor of auxin. ?

2. Plasticine (9- hydroxyfluorene -(9)- carboxylic acid)?

It can inhibit the division and elongation of apical meristem cells, inhibit the elongation of stems, promote the growth of axillary buds, and make plants develop into shrubs. Plasticine also has the characteristics that plants are not affected by gravity and light. ?

3. Chlorobenzene 2- chloroethyl trimethyl ammonium chloride. ?

Contrary to gibberellin, it can shorten internodes, shorten plants, thicken stems and deepen leaves. Enhance the ability of crops to resist cold, drought and salinity. Inhibit cell elongation, inhibit stem and leaf growth, but do not affect reproduction.
