Plasticine is an auxin conduction inhibitor, which can be absorbed by stems and leaves, conducted up and down in plants and transported through phloem and xylem. Because of its high content in young tissues, it can inhibit the mitosis of apical meristem, slow down the division speed, make mitochondria longer, thus inhibit the elongation of internodes, reduce the leaf area, hinder the downward conduction of terminal bud auxin, weaken the apical advantage, promote the growth of lateral buds, form tufted plants, inhibit the formation of lateral roots, and induce parthenocarpy. Can make hedgerow plants, ornamental plants, vines, shrubs and other trees short and compact. Increase the female flower ratio of cucumber, tomato, hemp, towel gourd and other crops or induce parthenocarpy.

Abroad, it is used to promote rice tillering, prevent coconut from falling, increase the fruit setting rate of cucumber, and delay or prevent lettuce bolting.
