1、The effect of exogenous methyl jasmonate and brassinosteroid on

Jasmonic acid and brassinosteroid are two kinds of plant growth regulators (PGRs) that are used as chemical elicitors to induce defense against B. cinerea and promote the quality of crops in the post-harvest storage (Darras, 2012, Liu et al., 2018a).

2、Q&A: what are brassinosteroids and how do they act in plants?

A full elucidation of brassinosteroid signalling events and their integration with other signalling pathways will enable brassinosteroid to be applied in agriculture.

3、Brassinosteroids Application in Ornamental Crops: A Review

Brassinosteroids are synthesized from different plant sterols. The biosynthetic pathway of brassinolide was first studied using feeding experiment on cell culture of Catharanthus roseus [9] and it involves three steps.

In this research, the impact of brassinosteroids (BRs) on the production rate, quality, photosynthesis efficiency, and nutrient uptake are being assessed.

Brassinosteroids – Role In Agriculture

Brassinosteroids (BRs) are a class of plant hormones that play a significant role in various physiological processes, including cell elongation, cell division, seed germination, flowering, and stress tolerance. They are structurally similar to animal steroid hormones.

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).

Brassinosteroids (BRs) Role in Plant Development and Coping with

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].

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.

Brassinosteroid is a plant growth regulator primarily used to promote plant growth and development. Applying brassinosteroid to roses can effectively accelerate their growth, enhance disease resistance, and improve flower quality. Below are detailed usage guidelines:

1. Preparation Phase

• Select healthy rose plants free from pests or diseases as experimental subjects.
• Determine the dosage of brassinosteroid according to product instructions or professional advice. Generally, a low dose is recommended, typically 50–100 grams per mu (or follow adjusted specifications for other units).
• Prepare necessary tools, including sprayers, gloves, masks, and protective equipment.

2. Application Phase

• Mix brassinosteroid with an appropriate amount of water and stir thoroughly before use.
• Spray the solution every 7–10 days during the rose-growing season. Adjust timing based on weather and plant conditions. For best results, apply in the morning or evening, avoiding high temperatures.
• Ensure even coverage across the entire plant, especially on leaves. Pay extra attention to new shoots and tender leaves.

3. Key Precautions

• Wear personal protective equipment (mask, gloves) to avoid skin or eye contact.
• Avoid application during rainy or windy weather to prevent reduced effectiveness.
• Discontinue use immediately if adverse reactions occur (e.g., yellowing or wilting leaves) and consult professionals.
• Monitor soil health, as brassinosteroid may affect soil microorganisms. Maintain adequate soil fertility.

4. Post-Application Management

• Adjust irrigation and fertilization to match the roses’ needs after using brassinosteroid.
• Observe plant growth regularly and modify dosage/frequency as needed.
• Clean up faded flowers and dead leaves after the blooming period to prepare for the next growth cycle.

brassinosteroid is an effective growth regulator that can significantly enhance rose growth and quality. Proper personal protection and rational application are critical to ensuring safety and optimal results.
