1、Exogenous application of brassinosteroids regulates tobacco leaf size
Brassinosteroids (BR) play diverse roles in the regulation of plant growth and development. BR promotes plant growth by triggering cell division and expansion. However, the effect of exogenous BR application on the leaf size and expansion of tobacco is unknown.
2、Application Methods of Brassinosteroids in Tobacco Cultivation
Timing and Application Methods: Apply brassinosteroids during key growth stages, particularly during vigorous growth and maturation. Application methods may include foliar spraying, drip irrigation, or seed soaking, depending on plant habits and soil conditions.
3、Brassinosteroids application induces phosphatidic acid production and
Brassinosteroids (BRs) are steroid hormones regulating various aspects of plant metabolism, including growth, development and stress responses. However, little is known about the mechanism of their impact on antioxidant systems and phospholipid turnover.

Exogenous application of brassinosteroids regulates tobacco
However, the effect of exogenous BR application on the leaf size and expansion of tobacco is unknown. Tobacco seedlings are treated with different concentrations of exogenous 2,4-epibrassinolide (EBL) [control (CK, 0molL 1 ), T1 (0.5×10 7 molL 1 ), and T2 (0.5×10 4 molL 1 )].
Brassinosteroids (BRs) Role in Plant Development and Coping with
The application of BRs has the potential in inducing tolerance against various plant diseases caused by the Tobacco mosaic virus (TMV) in tobacco and Xanthomonas oryzae and Maganoprothe grisea in rice [16, 111].

Brassinosteroids, also known as brassinolides, are a type of plant hormone that promotes growth and enhances stress resistance in plants. In agricultural production, brassinosteroids are widely used in tobacco cultivation to improve quality and yield. Below is a detailed guide on their application methods and precautions:
1. Application Methods of Brassinosteroids in Tobacco
(1) Foliar Spraying Dilute brassinosteroids to the recommended concentration and apply evenly to tobacco leaves using a sprayer. Ensure uniform distribution to avoid overuse, which may cause phytotoxicity. After spraying, provide adequate ventilation to facilitate absorption.
(2) Soil Application Mix brassinosteroids with organic fertilizer and spread evenly around the root zone of tobacco plants. Avoid direct contact with roots to prevent damage. Water appropriately after application to aid dissolution and absorption.
(3) Seed Treatment Soak seeds in a solution mixed with brassinosteroids at the recommended ratio to improve germination rates and seedling growth. The soaking time is typically around 48 hours.
2. Precautions for Using Brassinosteroids in Tobacco
(1) Dose Control Adjust the dosage based on the growth stage of tobacco and environmental conditions. Excessive use may lead to rapid, uncontrolled growth and reduced quality, while insufficient doses may fail to deliver expected yield benefits. Follow recommended dosages strictly.
(2) Combination with Other Fertilizers Brassinosteroids can be mixed with nitrogen, phosphorus, or potassium fertilizers to enhance nutrient uptake. monitor interactions between substances to avoid adverse reactions.
(3) Safety Considerations As a plant hormone, handle brassinosteroids carefully to avoid ingestion or skin contact. Monitor crop responses during use and discontinue immediately if abnormalities occur. Consult professionals if needed.
(4) Avoid Mixing with Pesticides Brassinosteroids may react with certain pesticides, reducing efficacy. Observe buffer periods and application guidelines to prevent chemical interactions.
(5) Long-Term Use Caution Extended or excessive use may induce tolerance in crops, affecting growth. Apply brassinosteroids adhering to the principles of "optimal timing and moderation" rather than prolonged continuous use.
Brassinosteroids offer significant advantages in tobacco cultivation, but their effective use requires careful dose management, synergistic fertilization, safety measures, avoidance of pesticide interactions, and cautious long-term application. When applied rationally, brassinosteroids can enhance tobacco quality and yield, delivering greater benefits to agricultural production.
