1、Brassinosteroids: Molecular and physiological responses in plant growth

Brassinosteroids improves crop yields by altering plant metabolism and protecting plants from several abiotic stresses. Brassinosteroids regulate gene expression and signal transduction pathways to stimulate abiotic stress tolerance.

2、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].

3、Unlocking the potential of brassinosteroids: A path to

In recent years, several studies have demonstrated that tissue-specific manipulation of brassinosteroids can substantially enhance yield in various economically important crops. These insights can inform the strategies used to engineer brassinosteroid pathways in a more targeted and effective manner.

Significance of brassinosteroids and their derivatives in the

Exogenous application of brassinosteroids at appropriate time can save plants from oxidative stresses. Brassinosteroids enhance carbon dioxide assimilation capacity, chlorophyll contents, antioxidants including ascorbate, carotenoids and proline under adverse environmental conditions.

Brassinosteroids

Brassinosteroids present a promising avenue for improving plant growth, stress tolerance, and crop productivity. However, further research and field trials are necessary to fully understand their potential and optimize their use in diverse agricultural systems.

Optimal Timing for Spraying Brassinosteroids on Crops

Spraying during the flowering period aids bud formation and development, leading to better-quality fruits. Pre-Harvest Spraying: Applying brassinosteroids before harvest accelerates fruit ripening and enhances quality.

Brassinosteroids Application in Ornamental Crops: A Review

Brassinosteroids (BRs) comprises of a novel group of steroidal hormones, having structural similarity with animal and insect steroids. They were first identified from rapeseed pollen and since then their presence has been documented in numerous plant species.

Brassinosteroids (BRs), as natural phytochemicals, are produced endogenously during fruit development and play a vital role in regulating its developmental, ripening and quality formation...

Brassinosteroid action in flowering plants: a Darwinian perspective

Since brassinosteroids induce pathogen resistance in rice plants and hence can suppress rice blast- and bacterial blight-diseases, genetic manipulation of BR-biosynthesis or -perception may be a means to increase crop production.

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 are a class of plant hormones that regulate growth, development, and stress resistance in plants. They can be applied via spraying or foliar application to promote crop growth and increase yield.

1. Classification and Functions of Brassinosteroids

Brassinosteroids are divided into two categories: exogenous and endogenous.

• Exogenous Brassinosteroids: Derived from non-plant sources (e.g., animal extracts, synthetic compounds), they promote growth, enhance stress resistance, and improve crop quality.
• Endogenous Brassinosteroids: Produced naturally by plants, they play a critical role in growth and development.

2. Applications of Brassinosteroids

a. Promoting Crop Growth

Brassinosteroids stimulate crop growth, especially under adverse conditions like low temperatures or drought. For example, winter applications can reduce growth stagnation caused by cold weather. They also improve photosynthetic efficiency and dry matter accumulation, boosting yields.

b. Enhancing Stress Resistance

Brassinosteroids improve crops’ ability to withstand harsh environments. For instance, they enhance drought resistance in hot, humid conditions and mitigate the effects of soil salinity in saline fields.

c. Improving Crop Quality

Brassinosteroids enhance taste, nutritional value, and shelf life. In fruit cultivation, they improve flavor and nutrients; in vegetables, they extend freshness and preserve quality.

3. Methods of Application

Brassinosteroids can be applied through spraying, topical application, or soaking:

a. Spraying

Dilute the solution and evenly spray it onto crop leaves using a sprayer. Optimal concentrations and timing vary by growth stage; apply during peak growth phases for best results.

b. Topical Application

Use a cotton swab or applicator to apply diluted solution to stems and roots. Suitable for fruit trees and vegetables, ensuring uniform coverage.

c. Soaking

Submerge crops (e.g., rice, corn) in a diluted solution for a controlled duration. Avoid oversoaking to prevent damage.

4. Precautions

• Concentration: Follow product guidelines to avoid overdosing (damage) or underdosing (ineffectiveness).
• Timing: Apply during active growth stages when nutrient uptake is highest.
• Target Areas: Adjust application sites (e.g., leaves for grains, stems/roots for fruits/vegetables).
• Safety Interval: Observe waiting periods when combining with fertilizers or pesticides.
• Soil Conditions: Conduct small-scale trials to optimize usage based on soil type and crop response.

Brassinosteroids are versatile plant hormones with significant potential to boost crop growth, stress resistance, and quality. Proper use—including appropriate concentration, timing, and application methods—can greatly benefit agricultural production.
