Benzylaminopurine is a synthetic growth regulator of moss , pure white crystal, industrial white or light yellow, odorless. Stable in acid and alkali, light and heat should not be decomposed. The solubility in water is small, 60 mg / l, and the solubility in ethanol and acid is large.
Benzylaminopurine is absorbed by germinated seeds, roots, shoots, and leaves, and has little mobility into the plant. It has a variety of physiological effects: 1. promote cell division, cytokinin activity; 2. promote non-differentiated tissue differentiation; 3. promote cell enlargement and growth; 4. promote seed germination; 5. induce dormant bud growth; 6. inhibit or promote the elongation of stems and leaves; 7. inhibit or promote the growth of roots; 8. inhibit the aging of leaves; 9. break the apical dominance, promote lateral bud growth; 10. promote flower bud formation and flowering; 11. induce female traits 12. Promote fruit set; 13. Promote fruit growth; 14. Induce tuber formation; 15. Transfer and accumulate substances; 16. Inhibit or promote breathing; 17. Promote evaporation and open pores; 18. Too high resistance to damage; Inhibition of chlorophyll decomposition; 20. Promoting or inhibiting enzyme activity and the like.
Techniques 1. Inhibition of leaf aging Rice with 10 mg/l concentration of benzylaminopurine in the 1-1.5 leaf stage of rice seedlings can achieve the effect of preventing aging and increasing survival rate.
2. Preservation of fruit and watermelon, melon with 100mg/l concentration of benzylaminopurine on the day of flowering, the effect of promoting fruit setting.
Pumpkin and zucchini can be used to promote fruit setting by applying benzylaminopurine at a concentration of 100 mg/l before flowering to the same day.
3. Inducing female traits Cucumber with 15mg/l concentration of benzylaminopurine in transplanted money soaked seedling roots for 24 hours, can increase the effect of female flowers.
4. Relieve aging and fresh-keeping cabbage with 30mg/l concentration of benzylaminopurine after spraying leaves or impregnation, can achieve the effect of prolonging the storage period.
The sweet pepper is immersed in the surface of the benzylamino hydrazine at a concentration of 10-20 mg/l before being harvested or immersed after harvesting, so as to achieve the effect of prolonging the storage period.
The lychee is harvested with benzylaminopurine at a concentration of 100 mg/l and then immersed for 1-3 min to achieve extended storage.
5. Promote fruit-bearing grapes with 100mg/l concentration of benzylaminopurine before soaking grape bunches before flowering, soaking inflorescence during flowering, can achieve the effect of promoting fruit setting and forming seedless grapes.
When tomatoes are immersed or sprayed with benzylaminopurine at a concentration of 100 mg/l, the effect of promoting fruit setting and anti-cavitation can be achieved.
Precautions 1.6-Benzylaminopurine is used as a green leaf for preservation. It is effective when used alone, and it is better to mix with gibberellin.
2. The product has poor conductivity and needs attention when used.
