6-BA ——Broad spectrum plant growth regulator

6-BA  is the first synthetic cytokinin. 6-BA can inhibit the decomposition of chlorophyll, nucleic acid and protein in plant leaves. At present, 6-BA is widely used in protecting flowers and fruits and promoting flower bud differentiation of citrus. 6-BA is a high-efficiency plant growth regulator. It performs well in promoting germination, flower bud differentiation, fruit setting rate, fruit growth and fruit quality. 6-BA is a broad-spectrum plant growth regulator, which can promote plant cell growth, inhibit the degradation of plant chlorophyll, improve the content of amino acids and delay leaf aging. It can be used for green bean sprouts and yellow bean sprouts. The maximum dosage is 0.01g/kg and the residue is less than 0.2mg/kg. It can induce bud differentiation, promote lateral bud growth, promote cell division, reduce the decomposition of chlorophyll in plants, and inhibit aging and keep green.

Method of application: (1) Promote lateral bud germination. When used in spring and autumn to promote the germination of rose axillary buds, cut the wound at 0.5cm above and below the axillary buds of lower branches, and apply an appropriate amount of 0.5% paste. In the shaping of young apple trees, it can be used in vigorous growth to stimulate the germination of lateral buds and form lateral branches; Fuji apple varieties were diluted 75 ~ 100 times with 3% solution and sprayed.(2) 6-BA promoted fruit setting of grapes and melons, treated grape inflorescences with 100mg / L solution 2 weeks before flowering to prevent flower and fruit falling; When melons bloom, the fruit setting can be improved by coating the melon handle with 10g / L. (3) Promote the flowering and preservation of flowers and plants. In the preservation of cut flowers and vegetables such as lettuce, cabbage, cauliflower, celery and Agaricus bisporus, and carnation, rose, chrysanthemum, violet and lotus, 100 ~ 500mg / L liquid can be sprayed or soaked before or after harvest, which can effectively maintain their color, flavor and aroma. (4) 6-BA improves grafting survival rate: treat scion base and rootstock head to promote healing and improve grafting survival rate. After scion, the grafted buds were smeared to promote the growth of grafted buds.
