1、芸苔素内酯调控植物生长发育及抗逆性的研究进展

At present, researches on brassinolide regulation of plant growth and development and improvement of plant stress resistance are abundant, and the regu-latory mechanism of brassinolide is clearer.

2、Brassinolide

体外研究 (In Vitro)： Brassinolide 是一种天然存在的植物激素，可促进生长、增加粮食颗粒和果树作物的产出，使植物对干旱和寒冷天气更耐受。 在 PC-3 细胞 中，Brassinolide 可诱导时间依赖性和浓度依赖性的毒性作用。 Brassinolide 的处理可引起时间依赖性的抗凋亡蛋白 Bcl-2 的表达降低及 G2/M 期细胞积累 [1]。 Brassinolide 是一种植物生长调节剂，通过在敏感的 CCRF-CEM 细胞 中逐步添加 vincristine (VCR) 获得人 T 淋巴母细胞样细胞系 CCRF-VCR 1000 的多药耐药 (MDR)，并初步探讨其逆转作用机制。

3、芸苔素内酯_百度百科

芸苔素内酯（Brassinolide，BR），化学式C28H48O6，是一种甾醇类植物内源激素，于1979年首次从油菜花粉中分离，1996年被科学界认定为第六大类植物激素。 作为高效、广谱、低毒的植物生长调节剂，它通过促进细胞分裂与伸长、提高叶绿素含量与光合效率来调控植物生长，兼具促根壮苗、保花保果、增产提质的作用。 同时，它能显著增强作物抗旱、抗寒、抗盐碱等抗逆性，并有助于缓解药害。 广泛应用于水稻、小麦、果树、蔬菜等多种作物。 使用时需注意适宜浓度，避免与除草剂及碱性农药混用。 1970年，美国学者从油菜花粉中提取出一种活性物质，发现它同样可以促进大豆的生长，并将其命名为“油菜素” [13]。

4、Brassinolide

These results clearly demonstrated the essential function of brassinosteroids for the growth and development of plants. Brassinolides stimulate shoot elongation, gravitropism, and differentiation of xylem, but inhibit phloem and root development. They also inhibit anthocyanin biosynthesis.

5、(PDF) Advances in Brassinolide Regulation of Plant Growth

Furthermore, we also compared different EBL application methods and concluded that seed priming and foliar application are more productive as compared with root application method.

Brassin

In order to promote the application of brassinolide in agricultural production, this paper reviewed the biological activity and the application of brassinolide in crops, such as grain, fruits and vegetables.

There are so many uses for brassinolides!

It can not only promote growth and development, promote fruit setting, promote fruit expansion, but also improve crop resistance. Reduce the occurrence of pests and diseases, improve yield and quality.

Common brassinolide effects and use precautions

The application methods of Brassinolide are mainly foliar spraying and soil root irrigation. Foliar spraying absorbs quickly and has a rapid effect, which is suitable for situations where rapid nutrition supplementation is needed or to cope with sudden adversity.

Role of Brassinosteroids on Antioxidants Regulation Under Abiotic

Results demonstrated that the application of brassinosteroids, combined with zinc stress, significantly enhanced germination percentage (about 47.06, 63.64, and 120%), speed of germination (about ...

Several Situations Where Brassinolides Must Be Prohibited

Brassinolide is a biomimetic sterol-based chemical substance with a specific optimal concentration. Using excessively high concentrations will not only be wasteful but may also cause varying degrees of inhibitory effects on crops.

Gongcai is a common vegetable rich in nutritional components such as vitamins, minerals, and dietary fiber. Brassinolides are natural plant growth regulators that can promote plant growth and development.

The effectiveness of applying brassinolides depends on multiple factors, including the type of brassinolide, concentration, application method, and the plant’s growth environment. Generally, the outcomes relate to the following factors:

1. Type of Brassinolide: Different brassinolides have distinct mechanisms and effects. Selecting the appropriate one is critical. For example, some enhance photosynthesis and increase yield, while others suppress growth to prevent pests and diseases.

2. Concentration: Higher concentrations often yield better results, but excessive levels may harm plants. Choosing the right dosage is essential.

3. Application Method: How brassinolides are applied impacts their efficacy. Some require direct spraying onto plants, while others need dilution in water or incorporation into soil. Timing also matters; effects typically take time to manifest after application.

4. Plant Growth Environment: Environmental conditions influence effectiveness. Brassinolides work better under adequate light, and early growth stages often respond more effectively.

To maximize results, consider these strategies:

1. Select Appropriate Brassinolides: Choose based on specific needs (e.g., opt for photosynthesis-boosting types for higher yield or growth-suppressing ones for pest resistance).

2. Adjust Concentration: Tailor the dose to plant requirements. While higher concentrations may amplify effects, avoid overdosing to prevent damage.

3. Optimize Application Methods: Use methods suited to goals (e.g., spraying, soaking, or soil mixing).

4. Account for Growth Conditions: Apply in well-lit environments or during early growth phases for better outcomes.

treating Gongcai with brassinolides can enhance growth and yield, but success requires selecting the right product, adjusting concentration, using proper methods, and considering environmental factors. By addressing these aspects, the effectiveness of brassinolides can be significantly improved.
