Brassinosteroids

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

What is Brassinolide ?

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)

How it helps plant to grow better and yield more?

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
