1、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.

2、Brassinosteroids

Brassinosteroids (BRs) are endogenous plant hormones essential for the proper regulation of multiple physiological processes required for normal plant growth and development.

3、Brassinosteroids

The discovery of Brassinosteroids (BRs) can be traced back to 1941 when Mitchell and Whitehead of United States, Department of Agriculture (USDA, Beltsville, MD), reported that pollen extracts often have growth-promoting properties on other plant tissues.

4、Brassinosteroid

In agriculture, brassinosteroids are applied exogenously as growth regulators to enhance crop performance. Synthetic BR analogs, such as 24-epibrassinolide, are used to boost seed germination, improve fruit set, and increase resistance to abiotic stresses like salinity and cold.

Brassinosteroids in growth control: How, when and where

In this review, we outline the evolution of brassinosteroid research, discuss the contribution of whole-plant-based and the more recent tissue-specific-based approaches and highlight a recently reported mechanism controlling spatial distribution of brassinosteroids.

Prospects of brassinosteroids in medicinal applications

Brassinosteroids (BRs), a class of plant-specific steroid hormones, control many of the developmental and physiological processes like their animal counterparts, including regulation of gene expression, cell division and expansion, differentiation, programmed cell death, and homeostasis.

Brassinosteroid

BRs can have high positive impact on the future of agriculture by regulating important horticultural and agronomic traits (Tong and Chu 2018). All BRs can be distributed into three main categories based on carbon-number of each steroid molecule (i.e., C 27, C 28 and C 29) (Fujioka and Yokota 2003).

Crucial Roles of Brassinosteroids in Cell Wall Composition and

Since their discovery, multiple bioactive BR has been described, and they can be classified into three groups, depending on the total number of carbons: C 27 -, C 28 - and C 29 -type. Their basic structure is a 5α-cholestane, 5α-ergostane and 5α-stigmastane, respectively.

Brassinosteroid is a plant growth regulator primarily used to promote plant growth and development. It works by inhibiting the synthesis of abscisic acid (ABA) in plants, enhancing their adaptability to environmental factors such as light and temperature, improving stress resistance, and accelerating growth and development.

Regarding the application frequency of brassinosteroid, it is generally recommended to follow the dosage instructions provided in the product manual. If the manual does not specify a clear frequency, the following factors should be considered to determine an appropriate schedule:

1. Plant Growth Stage: Different growth stages may require varying concentrations of brassinosteroid. Higher concentrations are often needed during early growth to stimulate development, while lower concentrations may suffice once growth stabilizes. Adjusting frequency according to the plant’s stage is critical.

2. Environmental Conditions: Environmental factors significantly impact plant growth. In hot, humid conditions, plants may benefit from increased application frequency due to stress. Conversely, in cold or dry environments, reducing frequency may be necessary.

3. Plant Health Status: Vigorous plants with high nutrient demands may tolerate more frequent applications, while weaker or slower-growing plants might require reduced frequency to avoid overload.

4. Plant Variety: Sensitivity to brassinosteroid varies by species. Some varieties may be prone to damage from excessive use, while others can withstand higher concentrations. Selecting a suitable formulation for the specific plant type is essential.

5. Application Method: Foliar spraying and soil application yield different results. Foliar spraying provides rapid growth stimulation but risks toxicity if overused, whereas soil application offers prolonged effects but requires caution to avoid soil contamination. Adjust frequency based on the method used.

brassinosteroid application frequency should be tailored to the plant’s growth stage, environmental conditions, health status, variety, and application method. Always consult the product manual first, then customize the schedule accordingly. Monitor plant responses closely; if adverse effects occur, adjust the frequency or discontinue use promptly.

Key Note: Prioritize the product manual’s guidelines and observe practical outcomes to optimize results while minimizing risks.
