Plasticine can be absorbed by seeds, roots and leaves, and its distribution in plants has no polarity, and its transportation direction mainly depends on the growth and development stage of plants when used. In the vegetative growth stage, it mainly transported upward, while in the vegetative storage period of fruit trees, it was more in line with the transportation direction of photosynthetic products and moved to the base. After it is inhaled into plants, it accumulates in active centers such as buds and split cambium, and the split tissue may be its main site of action.
Plasticine is an inhibitor of auxin. It is absorbed by stems and leaves, and then transmitted to the whole body after being absorbed by plants, which hinders the downward transportation of endogenous hormones in terminal buds, improves the activity of indoleacetic acid oxidase and reduces the content of auxin. The high content of chemical substances in the whole tender tissue 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, prevent the apical bud from conducting auxin downwards, weaken the apical advantage, promote the growth of lateral buds, form tufted plants and inhibit the formation of lateral roots. 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.
