Brassinolide

Brassinosteroids were first isolated from pollen grain of rape flowers (Brassica sp). It has the following features:

• Chemical Name: 2a, 22R – Tetrahydroxy-24S-cymene-b-7 oxygen-5a gallbladder – 6 – ketone. Brassinositiod : It is plant steroid
• Molecular weight: 494
• Solubility: Isopropyle alcohol, Methanol, chloroform and acetone
• Non toxic: It is safe to human, birds and fish

• A new 6th generation plant growth harmon after Auxines, Gibberellins, Cytokinins, Ascissic acid, Ethylene.
• It is polyhydroxy steroid.
• It interact with GA in cell wall elongation.
• It works independently to increase cell division.
• It shows synergetic effect with many plant growth regulators.
• It is effective at very low concentration say PPB (Parts per billion)

• Accelerated cell division and cell elongation, increases diameter, weight and size of fruits.
• When used in combination with GA gives best results.
• Cell wall expansion takes place.
• Improves the fertility of reproductive organs when used at flowering stage.
• Increase photosynthetic activity.
• It keeps fruit green for longer time.
• Seed weight increases, bolder seeds are produced.
• Increase in plants resistant powers towards disease and harsh condition.
• It helps plant to over come phyto toxicity effect of other chemicals.
• It increases ability to resist drought.
• New rooting comes out after spray.
• It increase enzyme and harmone production in plants to help in more Sugar formation and more Nuclic Acid production.
• Quality of fruit improves due to favorable factors. Such as more TSS, Brix, Ascorbic Acid etc.
• GA is soluble in Brassinolide formulations. Used in combination.
• Promotes early and uniform seed germination
