| Paclobutrazol 95% tc Plant growth regulator |
| Application | 1. Changes in Endogenous Hormone Levels
Paclobutrazol can inhibit gibberellin synthesis, delay growth, shorten internodes, and dwarf plants. It reduces the synthesis or metabolism of indoleacetic acid, promotes the increase of the endogenous abscisic acid content in the plant, and can also regulate the ethylene release of the plant. Paclobutrazol can make plant leaves become dark green, increase the content of photosynthetic pigments such as chlorophyll, increase the content of nucleic acid and protein in plants, improve the anti-aging ability of plants, and make plants have strong vitality.

| 2. Improve the stress resistance of plants
Paclobutrazol can improve the ability of plants to resist stress and bacteria. It can make plant epidermal cells expand, causing stomata to be squeezed and sinking, causing stomata resistance to increase, transpiration to decrease, and water loss to decrease. By alleviating water shortage, the stress on plant cells is alleviated, normal growth and development can be carried out, and the plant's own drought resistance ability is enhanced. The application of paclobutrazol can improve the ability of plants to resist cold injury and freezing injury. After application of paclobutrazol, the content of the stress hormone abscisic acid in the plant is increased, and the damage to the leaf cell membrane caused by low temperature is reduced.

3. Promote lateral bud germination and growth
Paclobutrazol can inhibit apical dominance and promote the germination and growth of lateral buds. For example, the application of paclobutrazol can make rice seedlings tiller early and more tiller, the plant becomes shorter, and the stem base becomes thicker.

4. Bactericidal effect
Paclobutrazol was first developed as a fungicide, and it has inhibitory activity against more than 10 pathogenic bacteria such as rape sclerotinia, wheat powdery mildew, rice sheath blight and apple anthracnose. Weeds dwarf, slow growth and reduce damage.

5. Application on fruit trees
Control the growth of shoots and dwarf fruit trees; promote flower bud differentiation and increase flower volume; adjust fruit set rate; change harvesting period to improve fruit quality; reduce summer pruning; improve drought resistance and cold resistance of fruit trees. |
