1、Brassinosteroids: Molecular and physiological responses in plant growth

Exogenous application of BR significantly increased photosynthetic activities of many plants under various stresses, including low temperature, weak light, and calcium nitrate stress (Niu et al., 2016; Li et al., 2016; Shu et al., 2016).

2、Optimal Application Timings for Brassinosteroid in Wheat

Timing of Application: Apply brassinosteroid in the morning or evening to avoid intense midday sunlight. Additionally, refrain from spraying during rainy weather or strong winds, as this may reduce effectiveness.

3、The Role of Brassinosteroids in Plant Cold Stress Response

Recent studies have shown that low temperatures affect BR biosynthesis in many plant species and that BR signaling is involved in the regulation of plant tolerance to low temperatures, both in the CBF-dependent and CBF-independent pathways.

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

Brassinosteroids (BRs) are a group of polyhydroxylated steroidal phytohormones that are required for the development, growth, and productivity of plants. These hormones are involved in regulating the division, elongation, and differentiation of numerous cell types throughout the entire plant life cycle.

5、Brassinosteroid

Brassinosteroids are steroidal compounds consisting of a C27, C 28 or C 29 side-chain and two ring structures – A and B rings (Bagjuz & Tretyn, 2003). They have a duel function in plants, promoting growth and providing protection against environmental stresses.

Roles of Brassinosteroids in Mitigating Heat Stress Damage in Cereal

Temperature influences the rate of plant metabolic and developmental processes that ultimately determine the production of grains, with high temperatures causing a reduction in grain yield and quality. To ensure continued food security, the tolerance of high temperature is rapidly becoming necessary.

Optimal Timing for Applying Brassinosteroid to Radishes

Start application when seedlings have 2–3 true leaves, using 20–30 grams of brassinosteroid per mu (approx. 0.067 hectares). Dilute with water and spray evenly over the plants.

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.

Optimal Dilution Ratio for Brassinosteroid Application in Radish

Determine Appropriate Concentration: The concentration of brassinosteroid significantly impacts its efficacy. Generally, higher concentrations yield stronger effects, but excessive levels may accelerate growth beyond optimal rates, potentially reducing yields.

Application of brassinosteroids for improving crop production: from

Brassinosteroids have a number of unique properties, including the ability to increase productivity and plant resistance to biotic and abiotic stressors in extremely low concentrations. The steroid hormones used in agriculture are chemically synthesized.

Brassinosteroids, also known as gibberellins, are plant hormones that exhibit various physiological activities, including promoting plant growth and enhancing stress resistance. In agricultural production, brassinosteroids are widely used to accelerate crop growth, increase yields, and improve quality. the effectiveness of brassinosteroids is significantly influenced by application temperature. Below is a detailed analysis of the optimal temperature for brassinosteroid use:

1. Effect of Temperature on Brassinosteroid Absorption

Brassinosteroids are primarily absorbed through plant roots, and their absorption efficiency is closely tied to soil temperature. Research indicates that when soil temperatures fall below 10°C, absorption rates decrease markedly due to reduced root activity under low temperatures. To maximize absorption, fertilization should be carried out in warmer conditions, avoiding cold seasons.

2. Effect of Temperature on Brassinosteroid Metabolism

The metabolic process of brassinosteroids within plants is temperature-dependent. High temperatures enhance enzyme activity, facilitating metabolism and transformation. Conversely, low temperatures inhibit enzymatic activity, slowing metabolic rates and reducing efficacy. application should occur within an optimal temperature range to promote efficient metabolism.

3. Effect of Temperature on Brassinosteroid Efficacy

The effectiveness of brassinosteroids depends on their concentration within plants. Within a certain range, higher temperatures increase intracellular concentrations, boosting efficacy. excessive temperatures may decompose or deactivate the hormone, diminishing its effects. Thus, selecting an appropriate temperature window is critical for maintaining effectiveness.

4. Effect of Temperature on Brassinosteroid Safety

Brassinosteroids exhibit mild toxicity, and prolonged or excessive use may harm plants. During application, dosage and frequency should align with crop growth stages and needs to prevent toxicity accumulation at high temperatures. Additionally, crop health should be monitored, and adjustments made promptly if abnormalities arise.

5. Effect of Temperature on Economic Viability

From an economic perspective, optimized fertilization strategies improve resource efficiency and reduce costs. By tailoring brassinosteroid use to crop requirements and market conditions, farmers can minimize expenses while maximizing returns.

application temperature profoundly impacts brassinosteroid absorption, metabolism, efficacy, safety, and cost-effectiveness. To ensure optimal results, fertilization practices should consider crop-specific needs and environmental conditions. Monitoring crop responses remains essential for timely issue resolution.
