1、Multifunctional Role of Brassinosteroids in Plant Growth, Development

Brassinolide (BL) is the most active form of BR, which was refined from over 200 kgs of the pollen sample of rapeseed or Brassica napus. After the process of purification, the structure of BL is determined through x-ray analysis (Grove et al. 1979).

2、Brassinosteroids (BRs) Role in Plant Development and Coping with

Brassinolide (BL), the most active BR, was isolated in 1979 [11]. The most significant finding was the isolation of Brassinosteroid insensitive 1 (BRI1)—a receptor kinase that triggers an intracellular signaling cascade in response to extracellular BR perception [12].

3、Brassinolide

First isolated from the lipid extract of pollen grains of rapeseed, it was identified as brassinolide, a steroidal lactone considered the most active form of BR (Grove et al., 1979).

Homobrassinolide vs. Brassinolide: A Comparative Analysis of Bioactivity

For researchers, scientists, and drug development professionals, this guide provides an objective comparison of the biological activities of 28-homobrassinolide (HBL) and brassinolide (BL).

There are so many uses for brassinolides!

Brassinolide is a new type of green and environmentally friendly plant growth regulator, and it is the plant endogenous hormone with the highest activity and the most functions found so far.

What’s Brassinolide Details?

In terms of biological activity, 28-homobrassinolide has the best effect, while 22,23,24-trisepibrassinolide has a poor effect. For farmers, it is very important to choose the right type of brassinolide.

There are many types of brassinolide, which one is better?

Compared with the 5 kinds of growth regulators discovered earlier, it has the highest effect because of the smallest amount of brassinolide and is called the 6th plant hormone.

Brassin

Brassinolide has the strongest biological activity in natural brassin, which is known as the sixth group of plant hormones, and it is highly effective, broad-spectrum and non-toxic plant growth regulators (PGR).

A Comparative Analysis of the Bioactivity of Epibrassinolide and

Comparative studies have demonstrated that EBL is often more effective than other synthetic brassinosteroids, such as 28-homobrassinolide (HBL), in enhancing plant growth and photosynthetic efficiency.[4][5]

Brassinolide

Brassinolide is defined as the most active brassinosteroid that influences cell elongation and division at very low concentrations. It is a unique polyhydroxylated steroid with specific structural characteristics. AI generated definition based on: Reference Module in Biomedical Sciences, 2019

Brassinolide is a plant growth regulator primarily used to promote plant growth, increase yields, and improve quality. Based on its form, brassinolide can be categorized into the following types:

1. Liquid Brassinolide: This is the most common form, which can be directly sprayed onto plant leaves for absorption. Its advantages include ease of use, but it has drawbacks such as volatilization and a shorter duration of efficacy.

2. Solid Brassinolide: Made by mixing liquid brassinolide with a carrier material, this form has a longer-lasting effect and better stability. It also reduces volatilization through encapsulation, enhancing its effectiveness.

3. Granular Brassinolide: Produced by granulating a mixture of liquid brassinolide and carrier materials, this form offers high stability and prolonged efficacy. It is also convenient for transportation and use due to its packaged form.

4. Cream-Based Brassinolide: Created through an emulsification process, this form has strong adhesion properties, allowing even application on plant surfaces. Like granular forms, it is easy to transport and use in packaged packaging.

5. Microencapsulated Brassinolide: Made via microencapsulation technology, this form provides superior stability, bioavailability, and enhanced efficacy. Its packaged design also simplifies storage and transportation.

Key Factors for Choosing the Right Form of Brassinolide:

1. Target Crop: Different crops absorb and utilize brassinolide differently. For example, liquid or granular forms are suitable for foliar spraying, while solid or cream-based forms may be better for soil application.
2. Application Method: Liquid forms can be sprayed directly, whereas granular forms require dilution before use.
3. Cost: Prices vary by form, so budget constraints must be considered.
4. Storage and Transport: Stability during storage and transit depends on the form. For example, microencapsulated or granular forms are more stable than liquid ones.

the optimal choice of brassinolide form depends on specific needs, crop type, application method, cost, and logistical considerations.
