Price Plant Growth Regulator 6-Benzylaminopurine 6BA 99%TC

Introduction

6-benzylaminopurine was the first artificially synthesized cytokinin. 6-BA has the ability to inhibit the decomposition of chlorophyll, nucleic acid, and protein in plant leaves, maintaining green and preventing aging; It is widely used in various stages of agriculture, fruit trees, and horticultural crops from germination to harvest, with various effects such as transporting amino acids, auxin, and inorganic salts to the processing site.

Application field
(1) The main function of 6-benzylaminopurine is to promote bud formation, and can also induce callus formation. It can be used to improve the quality and yield of tea and tobacco. The fresh-keeping of vegetables and fruits and the cultivation of rootless bean sprouts can obviously improve the quality of fruits and leaves.
(2) 6-benzylaminopurine is a monomer used in the manufacture of adhesives, synthetic resins, specialty rubber and plastics.

Synthesis method
Using acetic anhydride as raw material, adenine riboside was acylated to 2 ',3 ',5 '-trioxy-acetyl adenosine. Under the action of catalyst, the glycoside bond between purine bases and pentasaccharides was broken to form acetyladenine, and then 6-benzylamino-adenine was produced by reaction with benzylcarbinol under the action of tetrabutylammonium fluoride as phase transfer catalyst.

Application mechanism
Use: 6-BA is the first synthetic cytokinin. 6-BA can inhibit the decomposition of chlorophyll, nucleic acid and protein in plant leaves. At present, 6BA is widely used in citrus flower preservation and fruit preservation and promoting flower bud differentiation. For example, 6BA is a highly efficient plant growth regulator, which performs well in promoting germination, promoting flower bud differentiation, improving fruit setting rate, promoting fruit growth and improving fruit quality. 
Mechanism: It is a broad-spectrum plant growth regulator, which can promote the growth of plant cells, inhibit the degradation of plant chlorophyll, increase the content of amino acids, delay the aging of leaves, etc. It can be used for the hair of mung bean sprouts and yellow bean sprouts, the maximum usage is 0.01g/kg, and the residual amount 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, inhibit aging and preserve green.

Action object
(1) Promote lateral bud germination. When using in spring and autumn to promote the germination of the axillary buds of rose, cut 0.5cm on the upper and lower parts of the axillary buds of the lower branches and apply an appropriate amount of 0.5% ointment. In the shaping of apple saplings, it can be used to treat the vigorous growth, stimulate the germination of lateral buds and form lateral branches; Fuji apple varieties are sprayed with 3% solution diluted 75 to 100 times.
(2) Promote fruit setting of grapes and melons by treating grape inflorescences with 100mg/L solution 2 weeks before flowering to prevent falling flowers and fruit; Melons blossom with 10g/L coated melon handle, can improve fruit set.
(3) Promote the flowering and preservation of flower plants. In lettuce, cabbage, flower stem ganlan, cauliflower, celery, bisporal mushroom and other cut flowers and carnation, roses, chrysanthemums, violets, lilies, etc. fresh-keeping, before or after harvesting can be used 100 ~ 500mg/L liquid spray or soak treatment, can effectively maintain their color, flavor, aroma and so on.
(4) In Japan, treating the stems and leaves of rice seedlings with 10mg/L at 1-1.5 leaf stage can inhibit the yellowing of the lower leaves, maintain the vitality of the roots, and improve the survival rate of rice seedlings.

Suitable crop
Vegetables, melons and fruits, leaf vegetables, cereals and oils, cotton, soybeans, rice, fruit trees, bananas, lychee, pineapple, citrus, mango, date, cherry, strawberry and so on.

Attention to use
(1) The mobility of cytokinin 6-BA is poor, and the effect of leaf spray alone is not good, so it should be mixed with other growth inhibitors.
(2) As a green leaf preservation, cytokinin 6-BA has an effect when used alone, but the effect is better when mixed with gibberellin.

Matters needing attention
(1) Avoid contamination of eyes and skin with liquid medicine.
(2) No special antidote, according to the symptoms of symptomatic treatment.
(3) Store in a cool and ventilated place.
