In fruit trees, used to prevent disease brassinosteroid general concentration of 0.01% ~ 0.02%, if you want to increase production, can be used before flowering 0.01% brassinosteroid; in tomatoes, with 0.01% ~ 0.02% brassinosteroid can make tomatoes ripening 4 ~ 7 days earlier; in peanuts, with 0.01% ~ 0.15% brassinosteroid solution soaked seeds for 8 ~ 12 hours, can improve the seed germination rate of more than 40%; in the rice, with 0.01%~0.02% brassinol solution soaking seeds for 12 hours, can significantly improve the seed germination rate.
