brassinolide

Brassinolide, a plant growth-promoting steroid isolated from Brassica napus pollen

Key function: Brassinolide have been reported to produce novel growth-promoting effect (increase cell elongation and cell division) when applied to young plants that are active. It is also known as plant hormone or BRASS PGR Growth Regulator.

  • Natural steroid found in plants.
  • Promotes cell elongation and division in plants.
  • It helps in increasing the percentage of fruit setting.
  • Regulates differentiation in tissue culture.
  • When applied during flowering stage, can decrease the chances of flower dropping and fruit dropping.
  • Improves the plant’s ability to deal with diseases.
  • Improves the growth of the germinating seed.
  • Can be used in drench or foliar feed applications.
  • Strengthens a plant’s immunity to stresses such as drought, salinity and cold.
  • Is an important element for plant growth and helps increase yield.

Key ingredients: Brassinolide is a plant hormone. The first isolated brassinosteroid, it was discovered when it was shown that pollen from rapeseed (Brassica napus) could promote stem elongation and cell division. The biologically active part was isolated and named brassinolide.

Product specification:

  • Product Name : 24-Epibrassinolide – Brassinolide – Plant Hormone – BRASS – BL
  • Cas No: [78821-43-9]
  • Structure Formula : C28H48O6
  • Molecular Weight 480.68
  • Appearance: White crystals
  • Purity: 0.1%
  • Melting point: 254-256°C

Mode of action:

  • Promotion of cell expansion and cell elongation; works with auxin to do so.
  • It has an unclear role in cell division and cell wall regeneration.
  • Promotion of vascular differentiation; BR signal transduction has been studied during vascular differentiation.
  • Is necessary for pollen elongation for pollen tube formation.
  • Acceleration of senescence in dying tissue cultured cells; delayed senescence in BR mutants supports that this action may be biologically relevant.
