2.The mechanism of action of Trans-Zeatin produced by Agreenco Bio:
The zeatin has two isomers in structure, cis and trans, and the biological activity of trans zeatin is stronger, often existing in the form of ribonucleosides or nucleotides. Functionally, it can promote cell division and affect other aspects of the cell cycle. Its functions also include preventing leaf senescence, reversing toxic effects on leaves, inhibiting root formation, and promoting bud formation at high concentrations.
Trans zeatin can promote plant cell division, prevent chlorophyll and protein degradation, slow down respiration, maintain cell vitality, and delay plant aging. The mobility within the plant body is poor, and it is generally transported through the xylem with transpiration water flow.
3.Applications fields of trans zeatin produced by Agreenco Bio:
(1) To promote the germination of callus tissue, it is generally used in combination with auxin, with a concentration of 0.5-2.0 milligrams per liter.
(2) To promote fruit setting, spraying 10 mg/L of zeaxanthin+GA325~50 mg/L+NAA20 mg/L throughout the entire plant during the peak flowering period can improve the fruit setting rate of jujube.
(3) Spraying leaves with 20 milliliters can delay yellowing and promote growth. In addition, treating some crop seeds can promote germination. Applicable crops: apples, potatoes, etc.
(4) Stimulate the growth and development of plant buds and roots, increase tillering, improve fruit size, and increase yield.
(5) Widely applicable to crops: Widely suitable for pre sowing soaking of various crops such as rice, cotton, tomatoes, potatoes, etc. It can provide protection and promote early germination and growth of strong seedlings; Spray of stems and leaves one week before harvest can keep fruits fresh; Soaking roots before transplanting seedlings can avoid damaging the roots, facilitate recovery, and promote healthy growth; Spraying during the booting stage stimulates spike differentiation and increases grain number and weight.
