1、The Effect of Brassinosteroids on Rootting of Stem Cuttings in Two
The aim of the work was to evaluate the effect of two brassinosteroids: brassinolide (BL) and 24-epibrassinolide (24epiBL) as compared to the auxin rooting enhancer indole-3-butyric acid (IBA), on the rooting of stem cuttings in two Thunberg’s barberry cultivars ‘Maria’ and ‘Red Rocket’.
2、Brassinosteroids (BRs) Role in Plant Development and Coping with
BRs have been shown in numerous studies to have a positive impact on plant responses to various biotic and abiotic stresses.
3、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.
4、Effect of brassinosteroids on rooting and early vegetative
As the first steroidal plant growth regulator was isolated from Brassica napus, a generic name 'brassinosteroids' has been given to this new group of phytohormones.
Multifunctional Role of Brassinosteroids in Plant Growth, Development
As per previous reports, BRs can be obtained from various plant sources like maize stem tip, marigold leaves, etc. However, extraction process is very difficult and BRs can be measured through high-performance liquid chromatography (HPLC).

Brassinosteroids are a group of over seventy steroid compounds whose discovery in lower and higher plant organisms created new possibilities of plant growth control.
Practical applications of brassinosteroids in horticulture—Some field
The presence of brassinosteroids (BS) has been demonstrated in almost every part of plants, such as pollen, flower buds, fruits, seeds, vascular cambium, leaves, shoots and roots.
Brassinosteroids: The promising plant growth regulators on vegetable
In this research, the impact of brassinosteroids (BRs) on the production rate, quality, photosynthesis efficiency, and nutrient uptake are being assessed.
Brassinosteroids: Multidimensional Regulators of Plant Growth
As a long-term overarching objective, researchers should work to manipulate the BR pathway in crops and other plants so that plants can accommodate the stress created by greater fluctuations in these environmental parameters.

Brassinosteroids are a class of plant hormones primarily active in the roots and apical meristems of plants. They regulate physiological activities by modulating growth, development, and metabolic processes. In recent years, advancing research on plant growth regulators has led to widespread agricultural adoption of brassinosteroids as highly efficient tools for enhancing crop performance.
1. Basic Characteristics of Brassinosteroids
Brassinosteroids are naturally occurring hormones within plants, promoting growth and stress resistance. Compared to other growth regulators, they exhibit distinct advantages:
1.1 High Safety
Brassinosteroids are broadly used in agriculture and pose minimal risks to humans and animals. Studies confirm no significant toxicity, gene mutations, or carcinogenic effects from prolonged exposure.
1.2 High Efficiency
They significantly boost growth, yield, and quality while enhancing stress resistance (e.g., drought, salinity, pests).
1.3 Broad Spectrum
Effective across diverse plants, including food crops, cash crops, fruit trees, and ornamental species. They also improve non-target plant productivity and quality.
1.4 Reversibility
Their effects are temporary; plant growth normalizes after discontinuation, offering flexibility in agricultural applications.
2. Applications of Brassinosteroids in Cutting Propagation
Cutting propagation involves asexual reproduction via stem segments, widely used for flowers, vegetables, and fruits due to its speed and cost-effectiveness. slow growth and low yields often challenge this method. Brassinosteroids can address these issues:
2.1 Promoting Growth of Cuttings
Brassinosteroids stimulate root development, nutrient uptake, leaf expansion, and photosynthesis, enhancing survival rates and growth vigor.
2.2 Enhancing Stress Resistance
They strengthen disease and pest resistance, reducing pesticide reliance. Additionally, they improve tolerance to drought, cold, salinity, and other stresses.
2.3 Accelerating Flowering and Fruiting
Brassinosteroids promote bud differentiation, shorten reproductive cycles, and improve fruit quality, size, and market value.
2.4 Extending Shelf Life
By inhibiting respiration and ethylene production, brassinosteroids delay senescence, enhance freeze/heat tolerance, and reduce post-harvest losses.
3. Usage Guidelines for Brassinosteroids in Cuttings
To optimize results:
3.1 Select Appropriate Formulations
Choose brassinosteroid types tailored to plant species (e.g., cold-resistant formulas for sensitive crops).
3.2 Timing Matters
Apply during early growth stages for maximum efficacy, as sensitivity decreases in later phases.
3.3 Dosage Control
Follow the "principle of appropriate dosage" to avoid growth inhibition or death. Adjust based on species, stage, and environmental conditions.
3.4 Combine with Other Regulators
Synergize with gibberellins, abscisic acid, etc., but avoid antagonistic interactions.
4. Evaluating Effectiveness in Cuttings
Assess outcomes through:
4.1 Growth Observations
Monitor metrics like height, leaf color, and yield improvements.
4.2 Physiological Measurements
Analyze chlorophyll content, respiration rates, and ethylene emissions to gauge adaptability.
4.3 Stress Testing
Evaluate resilience under drought, cold, or salinity stress.
4.4 User Feedback
Gather insights from farmers to refine formulations, pricing, and strategies.
5. Challenges and Solutions in Cutting Applications
Despite benefits, challenges remain:
5.1 Avoid Overdosing
Excessive use may harm plants. Emphasize training for safe application.
5.2 Compatibility with Other Regulators
Carefully pair brassinosteroids with complementary agents to maximize synergy.
5.3 Ongoing Research
Conduct field trials and lab studies to deepen understanding of mechanisms and optimize usage.
5.4 Explore Alternatives
Investigate cost-effective and sustainable options, such as biotechnology-improved varieties or natural plant-based regulators.
