In the recent past, several new classes of PGRs such as brassinosteroids, salicylic acid, methyl jasmonates, polyamines etc. have been identified which play significant role in plant functioning.

3、Brassinosteroids: Multidimensional Regulators of Plant Growth

Brassinosteroids (BRs) are a group of polyhydroxylated plant steroid hormones that are crucial for many aspects of a plant's life. BRs were originally characterized for their function in cell elongation, but it is becoming clear that they play major roles in plant growth, development, and responses …

Brassinosteroids (BRs) are an important group of plant hormones involved in regulating plant growth and development, and they help plants to adapt to the environment [7].

5、Understanding brassinosteroid

Brassinosteroids (BRs) play a crucial role in regulating multiple biological processes in plants, particularly those related to crop productivity and stress tolerance.

Practical applications of brassinosteroids in horticulture—Some field

Brassinosteroids (BS) are a class of steroidal plant hormones which are highly stable and environment friendly. They are involved in a wide range of physiological and biochemical responses in plants. Their role in the increase in productivity of agricultural and oil seed crops is well established.

Brassinosteroids in Plants (With Diagram)

Brassinosteroids or brassins are a recently discovered group of steroids that have dis­tinct growth promoting activity in some plants especially in stems. These compounds were first isolated in 1979 from bee collected pollen grains of rape (Brassica napus), a mustard (hence the name brassins).

Crucial Roles of Brassinosteroids in Cell Wall Composition and

Brassinosteroids (originally brassins) were first described in the 70s as plant hormones, isolated from rape pollen (Brassica Napus L.) and tested in bean plants, where they induced internode elongation (Mitchell et al. 1970).

Brassinosteroids: perspective of biosynthesis, crosstalk, and role in

Among various kinds of BRs studied, the most common ones are catasterone (CS), typhasterol (TY), teasterone (TE), and brassinolide (BL) found in various plant species existing in variable environmental conditions.

Brassinosteroids are plant growth regulators primarily used to promote plant growth and development. When purchasing roses, selecting the appropriate brassinosteroid is crucial as it can significantly enhance the quantity and quality of blooms. Here are some recommendations for choosing brassinosteroids:

I. Understand the Mechanism of Brassinosteroids

Brassinosteroids mimic natural plant hormones such as auxins and gibberellins to stimulate growth and development. They promote cell division and elongation, increase leaf area, and improve photosynthetic efficiency, thereby accelerating plant growth. Additionally, they enhance stress resistance and survival rates in plants.

II. Choose Brassinosteroid Varieties Suitable for Rose Growth

1. Root-Promoting Brassinosteroids

   • Purpose: Stimulate root growth and development.
   • Characteristics: High in gibberellins, these regulators promote root expansion and nutrient/water absorption. They also improve cold and drought resistance in roses.

2. Flowering-Promoting Brassinosteroids

   • Purpose: Enhance flower bud formation and differentiation.
   • Characteristics: Rich in auxins, these regulators boost bloom quantity and quality. They also strengthen stress resilience, ensuring healthy growth under harsh conditions.

3. Seedling-Strengthening Brassinosteroids

   • Purpose: Promote robust seedling growth.
   • Characteristics: High in gibberellins, these regulators thicken stems, enlarge leaves, and improve pest/disease resistance. They also increase seedling survival and growth rates.

III. Consider Application Methods and Dosage

1. Application Methods:

   • Spraying: For foliar absorption (quick results).
   • Smearing: Apply to trunks/branches for direct tissue absorption.
   • Soaking: Use for soil treatment to penetrate deep layers.

2. Dose Control:

   • Adjust dosage based on plant size, growth stage, and environmental conditions. Overuse may cause excessive growth or deformities, while insufficient doses may be ineffective. Follow the principles of "appropriate amount, timing, and location."

IV. Coordinate with Other Plant Growth Regulators

For optimal results, combine brassinosteroids with other regulators:

• Pair with phosphorus/potassium fertilizers to improve nutrition.
• Mix with fungicides/pesticides to enhance pest/disease resistance.
• Note: Observe interactions between regulators and adjust doses if adverse reactions occur.

V. Recommendations

1. Select Reputable Brands: Choose trusted brands with professional technical support and reliable product lines.
2. Consult Experts: Seek advice from horticulturists, agricultural specialists, or institutions for region-specific guidance.
3. Read Instructions Carefully: Follow usage guidelines, precautions, and shelf life to avoid operational errors.
4. Evaluate Effects Regularly: Monitor plant growth for abnormalities (e.g., excessive stretching, deformities) and adjust strategies as needed.

Choosing the right brassinosteroid is key to improving rose growth quality and yield. By understanding their mechanisms, selecting appropriate types, controlling application methods, and coordinating with other regulators, you can create a healthier, more vigorous environment for roses.
