1、郑氏化工小讲堂：你真的了解芸苔素内酯吗？

芸苔素（brassinolide 简称BR）被学术界公认为第六大植物激素。 可以在大田作物、水果、蔬菜、花卉等使用。 具有强力生根、促进生长、提苗、壮苗、保苗、促进座果、果实膨大早熟、减轻病害缓解药害、协调营养平衡、抗旱抗寒、增强作物抗逆性等多重 ...

2、What are the differences between brassinoids, sodium nitrophenolate

Different crops have different stress resistance capabilities. For this point, it is undeniable that ethanol is the best, followed by sodium nitrophenate, but sodium nitrophenate is also more effective in improving fertilizer utilization and efficacy.

3、What’s Brassinolide Details?

Because different types of Brassinolide have different effects on plant growth. This article will introduce the specific situation of these 5 types of Brassinolide and focus on analyzing their differences.

4、What is brassinolide used for?

The combination of brassinolide + 920 can reduce the risk of phytotoxicity caused by using 920 alone. Brassinolide can balance the endogenous hormones of crops, enhance crop photosynthesis, promote balanced crop growth, and normal fruit expansion.

5、Brassinolide

Brassinolide是一种植物甾醇，最初从油菜（Brassica napus L.）花粉中分离出来，在植物生长、发育和逆境耐受性方面发挥重要作用。

Huangjia Natural Brassinolide +920: both fruit preservation and shoot

Huangjia Natural Brassinolide +920 has a strong combined effect. The formation of separation layer is related to the lack of nutrients, the absorption and operation of nutrients, and the flow of nutrients; the absorption, operation and flow of nutrients are affected by auxin.

Why is there such a big difference between both substances called

Some manufacturers unilaterally exaggerate the efficacy and activity of their products, resulting in great differences between the actual effects and publicity effects after farmers use them.

Brassinolide

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 misunderstandings of brassinolide, 5 major effects, and 5 classic

The combination of Brassinolide + 920 can reduce the risk of phytotoxicity caused by the use of 920 alone. Brassinolide can balance the endogenous hormones of crops, enhance photosynthesis of crops, promote balanced growth of crops, and normal fruit enlargement.

Comparison between Natural Brassinolide and Chemically Synthesized

All the brassinolides currently on the market can be divided into two categories from the perspective of production technology: natural brassinolide and synthetic brassinolide.

Brassinolide and 920 are both plant growth regulators primarily used to promote plant growth. The main differences between them lie in their modes of action, effects, and applicable crops.

1. Mode of Action: Brassinolide is a plant hormone that promotes growth by mimicking hormonal signals within plants. It mainly works by inhibiting ethylene synthase, thereby reducing ethylene production, delaying senescence, and enhancing growth. In contrast, 920 is a novel plant growth regulator with a different mechanism of action, which requires further research for full understanding.

2. Effects: Brassinolide is commonly used to promote the growth of fruit trees and vegetables, particularly during fruit enlargement and maturation stages. It effectively increases crop yield and quality while improving stress resistance. Meanwhile, 920 is primarily applied to cereals like rice and wheat, especially during jointing and booting stages. It enhances photosynthetic efficiency, boosts yields, and improves disease resistance and lodging tolerance.

3. Applicable Crops: Brassinolide is suitable for economic crops such as fruits, vegetables (e.g., apples, citrus, tomatoes, cucumbers), and ornamental plants (e.g., roses, peonies). In contrast, 920 is mainly used for staple crops including rice, wheat, and corn.

4. Application Methods: Brassinolide application involves diluting the solution and spraying or applying it topically, requiring careful dosage control to avoid phytotoxicity. For 920, usage varies depending on crop type and growth stage, often necessitating preliminary trials to determine optimal application methods and dosages.

5. Safety: As a natural plant hormone, brassinolide is generally safe for humans when used properly, though overapplication should be avoided. The safety profile of 920, being a newer regulator, is still under evaluation. Professional consultation is advised prior to use to ensure safety.

both brassinolide and 920 are effective plant growth regulators, but they differ in mechanisms, effects, and target crops. Selecting the appropriate product depends on specific crop types and growth stages, with careful dosage management to guarantee safe and efficient promotion of plant growth.
