1、Optimal Timing for Spraying Brassinosteroids on Crops

Pre-Harvest Spraying: Applying brassinosteroids before harvest accelerates fruit ripening and enhances quality. Additionally, it strengthens pest and disease resistance, reducing pesticide use and benefiting environmental protection.

2、Brassinosteroid seed priming positively affects leaf anatomy and gas

Preliminary in vitro analyses were carried out to identify the optimal hormonal priming treatment for sorghum seeds. Two concentrations (1 and 0.1 µM) of 24-epibrassinolide (24-eBL) were tested, and seeds were incubated in these solutions for 8 or 24 h, under gentle agitation (50 rpm) (Chakma et al., 2021; Alhammad et al., 2023).

In sorghum plants, there are reports of the exogenous application of bioregulators such as brassinosteroids (Vardhini et al. 2011) and salicylic acid (Arivalagan and Somasundaram 2016) in the attenuation of water deficit during initial growth.

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.

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.

Brassinosteroids: Multidimensional Regulators of Plant Growth

Brassinosteroids are a class of plant steroid hormones that are versatile regulators of growth, development, and responses to stresses such as extreme temperatures and drought. Brassinosteroids (BRs) are a group of polyhydroxylated plant steroid hormones that are crucial for many aspects of a plant’s life.

Optimal Timing for Brassinosteroid Application in Peanut Seedlings

1、Optimal Timing for Spraying Brassinosteroids on Crops Seed Treatment: Before sowing, soak seeds in a diluted brassinosteroid solution (prepared according to the specified ratio) for approximately 24 hours.

Role of brassinosteroids on horticultural crops

Moreover, their production is susceptible to sub-optimum environmental conditions, especially in facilities cultivation. Thus, practical application of BRs to horticultural crops for enhancing crops production and protection may have a promising prospect in the near future.

Brassinosteroid is a plant growth regulator widely used in agricultural production. It promotes plant growth and development, while improving yield and quality. Sorghum, as a vital food crop, aims for high productivity and superior quality, making the strategic use of brassinosteroid during its cultivation highly effective.

1. Optimal Timing for Brassinosteroid Application

The timing of brassinosteroid application depends on sorghum’s growth stages. Targeting critical phases such as the seedling, jointing, heading, and grain-filling stages yields the best results:

(1) Seedling Stage During the early seedling phase, when growth is slow, applying brassinosteroid stimulates root development and seedling survival. Typically, apply 20–40 ml per mu of diluted solution evenly to the root zone soil every 7–10 days.

(2) Jointing Stage As sorghum enters rapid stem elongation, brassinosteroid strengthens stalks and enhances lodging resistance. Apply 30–50 ml per mu one week before jointing, spraying uniformly on stem surfaces.

(3) Heading Stage To boost grain development and yield, apply 50–80 ml per mu one week before heading. Spray diluted solution on stems, leaves, and panicles.

(4) Grain-Filling Stage For improved grain plumpness and quality, apply 50–80 ml per mu one week before grain-filling. Spray stems, leaves, and panicles thoroughly.

2. Application Methods

(1) Dilution Ratio Adjust dilution based on variety, soil fertility, and weather. A typical dose is 20–40 ml per mu, modified as needed.

(2) Spraying Time Apply in early morning or evening to avoid midday heat, ensuring even coverage on stems, leaves, and roots.

(3) Target Areas Focus on stems, leaves, and panicles. For sorghum, prioritize these areas to maximize growth benefits.

(4) Frequency Apply once per growth stage (seedling, jointing, heading, grain-filling) for a total of four applications.

3. Precautions

(1) Dosage Control Strictly adhere to recommended doses (20–40 ml per mu). Excessive use may harm plants.

(2) Avoid Mixing with Pesticides Brassinosteroid may interact negatively with certain chemicals. Use separately to prevent reduced efficacy or adverse reactions.

(3) Environmental Protection As an organic phosphorus compound, handle brassinosteroid carefully to avoid water and soil contamination.

(4) Climate Considerations High temperatures or drought may reduce effectiveness. Adjust strategies based on weather conditions.

Brassinosteroid is a potent tool for enhancing sorghum yield and quality. By timing applications to key growth stages and following proper protocols, farmers can optimize results. Always prioritize precise dosing, environmental safety, and adaptability to climate conditions.
