How to use Brassinolide(BR) in peanuts and the benefits of using Brassinolide(BR)

Brassinolide (BR) is different from other plant growth regulators in promoting crop yield and improving quality.  When applied to peanuts, Brassinolide (BR) can promote growth and increase yields.  Peanuts grow steadily and the total number of fruits per plant is high.  So how do peanuts use Brassinolide (BR)?  What are the benefits of using brassinolides in peanuts?

How to use Brassinolide(BR) on peanuts
Brassinolide (BR) improves the cold resistance of peanut seedlings.  
Use Brassinolide (BR) solution with a concentration of 0.01~0.1 mg/L to soak peanut seeds for 24 hours to promote germination and emergence and increase the content of amino acids, soluble sugars and chlorophyll.  At the same time, Brassinolide (BR) solution treatment can slow down the degradation of chlorophyll, reduce the accumulation of membrane lipid oxidation product malondialdehyde, and can effectively improve the resistance of seedlings to low temperature;  Brassinolide (BR) can increase peanut yield, using 0.01% natural Brassinolide (BR) 5 grams, add 15 kilograms of water, and start spraying at the beginning of flowering (the ovary stalk is buried in the soil).  After spraying, the growth was stable, the total number of fruits per plant was large, and the yield increased by 22% compared with the control.

Benefits of using Brassinolide(BR) on peanuts
1.Reasonable application of Brassinolide(BR) to increase peanut yield
How to use:
During the peak flowering period of peanuts, it is the transition period from vegetative growth to reproductive growth.  At this time, proper control of vegetative growth can promote reproductive growth, which is beneficial to increasing peanut yield.

It can control the leggy growth of peanut stems, and the plant dwarfing effect can be obviously shown 5 days after spraying, regardless of the initial flowering stage, full flowering stage, or lower needle stage of peanuts.  Peanut plants that have been treated for a long time have thick stems, short internodes, compact plant shape, darker leaf color, thickened leaves, increased angle between petiole and stem, and increased light receiving area.  It has a significant inhibitory effect on peanut flowering, and the flowering amount decreases significantly within a few days after treatment.  The higher the concentration of the drug, the stronger the flower control effect, so the appropriate time must be chosen, otherwise it will lead to a reduction in yield.  While inhibiting vegetative growth, it can accelerate the accumulation of fruit pod substances and promote the growth and development of peanuts, so as to mature 5 days earlier and increase yield by 10%-50%.

2.Spray Brassinolide (BR) to make plants strong and increase the number of pods
Usage: After the peanut plants enter the full flowering stage and a small number of them have formed large fruits, spray with 1200 times Brassinolide (BR).  It can effectively control the excessive growth of stems and branches.  Until harvest, the length of stems and branches is still lower than 3/5 to 2/3 of the control.  The plant shape is compact (stable, strong, short-noded), which is conducive to ventilation and light transmission.  The chlorophyll content generally increases by 24% to 45%.  
Reduce late-stage ineffective flowers by about 29%, which is beneficial to promoting fullness of pods.  The number of fruits per plant increases by 4% to 30%, and the fruit filling rate increases by 4% to 10%.
