Product Detail

Brassinolide is a new green and environmentally friendly plant growth regulator ,it's have the characteristics of auxins, gibberellins, and cytokinins in their physiological effects: they can promote seed germination, regulate growth, increase production, promote fruit ripening. Brassinolide can be use alone or mix with gibberellic acid and cytokinin .

Brassinolide can be widely use in food crops such as rice, wheat, and potatoes, generally increase the production by 10%; when use in various economic crops such as fruit trees, vegetables, cotton, linen, and flowers, they can generally increase the production by 10- 20%, and the highest can reach 30%, significantly improve the quality, increase sugar content and fruit weight, and increase the beauty of flowers.

Functions

1. Sweetening and coloring
Brassinolide (BR) can be used on fruits, melons, and beans to make the fruit uniform, improve the appearance, increase the selling price, and increase income.
2. Delay leaf aging
It can keep green for a long time, strengthen chlorophyll synthesis, improve photosynthesis, and make the leaf color darker and greener.
3. Promote flower and fruit protection
When used during the flowering period and young fruit period, it can promote flower and fruit, prevent fruit drop and protect fruit.
4. Promote cell division and promote fruit expansion
It has a significant promoting effect on cell division, and has a promoting effect on the lateral and longitudinal growth of organs, thereby playing a role in expanding the fruit.
5. Increase production and high yield
It breaks the apical dominance, promotes the germination of lateral buds, can penetrate the differentiation of buds, increase the number of branches and flowers, thereby increasing the number of fruits and increasing yields.
6. Improve the commercial quality of crops
Induce parthenocarpy, prevent falling flowers and fruits, promote protein synthesis, increase sugar content, improve crop quality, and improve commercial quality.
7. Regulate and balance nutrition
The effect of mixing foliar fertilizer with brassinolide is particularly good. Foliar fertilizer can supplement plant nutrients; Brassinolide (BR) can transport nutrients evenly and conduct nutrients in a directional manner, so that both the nutritional growth and reproductive growth of crops can obtain reasonable nutrients.
8. Sterilization and efficiency enhancement, rapid recovery of growth
Fungicides can only inhibit diseases, but have little effect on the recovery of crop growth. The use of fungicides and brassinolides complements each other's advantages. Brassinolide (BR) has a good effect in assisting disease treatment and the crop recovers growth quickly.
9. Cold resistance, frost resistance, drought resistance, and disease resistance
After entering the plant body, Brassinolide (BR) not only enhances photosynthesis and promotes growth and development, but also has a special protective effect on the plant cell membrane system to resist adverse environmental damage.
10. Relieve pesticide damage
Timely use of Brassinolide (BR) plus high-quality foliar fertilizer can regulate nutrient delivery, supplement nutrition, reduce damage to crops caused by improper use of drugs, and accelerate the recovery of crop growth.

Natural Brassinolide and Chemically Synthesized Brassinolide:
Different sources：
Natural brassinolide and 14-Hydroxylated brassinolide: This is a natural substance that comes from organisms in nature, especially rapeseed. 28-homobrassinolide, 28-epihomobrassinolide, 24-epibrassinolide and 22,23,24-trisepibrassinolide: These species are sterol substances obtained by chemical synthesis.
Different degrees of activity
The biological activity of various types of brassinolide mainly depends on the activity and content of the steroidal alcohols themselves.
Natural brassinolide ＞14-Hydroxylated brassinolide＞28-homobrassinolide＞28-epihomobrassinolide＞24-epibrassinolide ＞22,23,24-trisepibrassinolide.

Parameters

Crops	Applied technology
Wheat	Soaking seeds at 0.05 ~ 0.5 mg/L for 24h promoted root development and increased plant height Spraying 0.05 ~ 0.5 mg/L on leaves at tillering stage can promote tillering Spraying 0.01 ~ 0.05 mg/L on leaves at flowering and booting stage increased seed setting rate, grain number per spike, spike weight and 1000-grain weight of weak flowers, and increased chlorophyll content of leaves, thus increasing yield
Corn	Spraying the whole plant or spraying silk with 0.01 mg/L at the stage of tasseling can obviously reduce the abortion rate of grain at the top of ear, and the effect of pre-tasseling treatment is better. After treatment, the leaf thickened, the leaf color was dark, the chlorophyll content was increased, the photosynthesis was enhanced, and the yield was increased obviously
Rice	Spraying 0.01 mg/L on rice leaves from late tillering stage to young panicle formation stage to flowering stage can increase panicle weight, grains per panicle and 1000-grain weight. If low temperature occurs at flowering stage, the seed setting rate can be obviously improved
Cucumber	Treating seedlings with 0.01 mg/L at seedling stage can improve the ability of seedlings to resist 7 ~ 10 ℃ low temperature at night
Tomato	When 0.1 mg/L was sprayed on the leaves during the period of fruit enlargement, the weight of fruit increased obviously
Eggplant	Soaking eggplant flowers below 17 ℃ at 0.1 mg/L can promote normal fruiting
Navel orange	Spraying 0.01 ~ 0.1 mg/L on the leaf surface at the peak of flowering and after the first physiological fruit drop, the fruit setting rate increased after 50 days, and it also had a certain sweetening effect
