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.

Application and compounding scheme of brassinolide!

Brassinolide itself has no nutrients, so the nutrient supply must be guaranteed, and "water, fertilizer, and conditioning" must be integrated so that brassinolide can play a better role in the plant.

Since then a number of steroids related to brassinolide have been isolated from various plant sources: these natural steroids, as well as synthetic ones, are often called brassinosteroids and, in this text, are abbreviated as BRs.

What Are the Best Fertilizers for Foliar Application on Apricot Trees?

Apricot trees, as one of the most important fruit trees, rely on proper fertilization management for healthy growth. When selecting suitable foliar fertilizers for apricot trees, several key factors must be considered: comprehensive nutrient composition, targeted efficacy, and application methods.

How Long Does It Take for Brassinolide Spray on Apricot Trees to Show

Promoting New Shoot Growth: Brassinolide stimulates cell division and elongation in apricot trees, accelerating new shoot growth. Within 2-3 weeks of application, the growth rate of new shoots increases, and their quantity rises.

Brassinolide is a plant growth regulator that promotes plant growth and development, enhances crop yield, and improves quality. As a vital fruit tree, apricot trees require scientific fertilization practices to ensure fruit quality and productivity. Below are detailed guidelines on using brassinolide and fertilization methods for apricot trees:

I. Methods for Applying Brassinolide to Apricot Trees

1. Select Suitable Varieties: Choose apricot cultivars adapted to local climates. For northern regions, prioritize cold-resistant and disease-tolerant varieties.
2. Soil Preparation: Prior to planting, plow and disinfect the soil to ensure loose, fertile, and pest-free conditions. Adjust soil pH to optimal levels for apricot growth.
3. Brassinolide Application: During planting, evenly spread an appropriate amount of brassinolide over the soil surface before sowing or transplanting. Avoid overapplication to prevent growth abnormalities.
4. Irrigation and Fertilization: Maintain adequate water supply, especially during dry seasons. Fertilize with nitrogen (N), phosphorus (P), and potassium (K) based on growth stages to support development.
5. Pest and Disease Control: Monitor for pests/diseases regularly. Use targeted pesticides or prune affected branches promptly to prevent spread.
6. Pruning and Training: Shape the tree according to growth habits and market demands to improve fruit quality and yield.
7. Harvesting and Storage: Timely harvest mature fruits and store them properly to avoid environmental damage.

II. Fertilization Methods for Apricot Trees

1. Base Fertilization: Apply sufficient organic fertilizers (e.g., animal manure, compost) or compound fertilizers before planting to provide essential nutrients.
2. Topdressing: During growth stages, apply additional fertilizers tailored to specific phases: bud germination, flowering, and fruit expansion.
3. Foliar Spraying: Directly spray nutrients onto leaves to enhance absorption efficiency and reduce environmental pollution.
4. Root-Zone Fertilization: Dissolve fertilizers in water and apply near roots to boost nutrient uptake.
5. Combine Organic and Synthetic Fertilizers: Use organic matter to improve soil structure while supplementing with synthetic fertilizers for rapid nutrient delivery.
6. Timing of Fertilization: Focus on spring (critical growth period) and reduce autumn applications (fruit maturation stage).
7. Control Application Rates: Adjust fertilizer amounts based on tree health to avoid overnutrition or deficiencies.
8. Diverse Application Methods: Use foliar sprays, soil incorporation, or root-zone drenching to address nutritional needs at different stages.
9. Post-Fertilization Management: Loosen soil and irrigate after fertilizing to improve aeration, water retention, and nutrient absorption.
10. Soil Nutrient Testing: Regularly analyze soil composition to adjust fertilization strategies and address imbalances.
11. Integrated Pest Management: Observe for pest/disease signs during fertilization and apply bio-pesticides or fungicides as needed to safeguard tree health.

Scientific use of brassinolide and optimized fertilization practices significantly enhance apricot productivity and fruit quality. Always follow safety protocols when handling brassinolide and prioritize eco-friendly, sustainable fertilization to minimize environmental impact.
