What is a swelling agent (what exactly is a swelling hormone, can it be used)
For ordinary consumers, when Youyou Resources Network hears that fruits and vegetables use swelling substances, they subconsciously think that such Vegetables and fruits are poisonous and harmful to the human body and cannot be eaten. What is swellin, can it be used in production, and is it toxic to the human body? Today, the editor helps you understand swelling hormones.
What are plant growth regulators?
Generally speaking, plant growth regulators refer to a class of substances that are artificially synthesized and have the function of regulating plant growth and development. Plant growth regulators mainly include five categories, mainly auxins (main products: indole acetic acid, indole butyric acid, naphthalene acetic acid, etc.) are mainly used to promote plant rooting and stem and leaf growth; cytokinins (mainly benzyl Aminopurine, etc.) can promote rapid cell division. Gibberellic acid (mainly gibberellic acid, chlorfenuron, etc.) is mainly used to promote cell division and cell elongation; abscisic acid (mainly S-inducer, thidiazuron, etc.) is mainly used to promote leaf, fruit, etc. The shedding of organs; the main function of ethylene (mainly ethephon) is to promote fruit ripening. Brassinolide is a plant growth regulator with multiple functions, generally known as the sixth type of plant growth regulator. These substances are mainly used to regulate the normal growth and development of crops, so they are called plant growth regulators.
The difference between plant hormones and growth regulators
Phytohormones are a large class of substances widely present in plants. Synthesized by plants themselves, used to regulate plant growth and development. These substances widely exist in almost all green plants and are used to regulate plant growth, flowering, fruiting, ripening, etc. The content of these endogenous hormones is different in different stages of plant growth, and the content of auxin in the seedling stage and vegetative growth stage is high, which is conducive to the rapid growth of plants. During the flowering and fruiting stage, the content of cytokinin and gibberellic acid is high, which is conducive to flowering. Plant growth regulators are synthetic substances in plants that are similar in structure and function to hormones. That is to say, phytohormones exist in plants and are synthesized by plants themselves, while plant growth regulators are artificially synthesized, which is the difference between phytohormones and plant growth regulators. They are basically the same in function.
What is swellin?
Swellin is a plant growth regulator that belongs to cytokinins and gibberellins. Because it can promote the rapid expansion of fruits, it is vividly called “swelling element” by farmers’ friends. The main products are gibberellic acid, chlorfenuron, choline chloride, 6-benzylaminopurine and other products. Brassinolide also has the effect of expanding fruit and can also be used as a swelling factor. These substances are all low or non-toxic. Among them, gibberellic acid is produced by gibberellic acid fermentation, and gibberellic acid is a pure natural plant endogenous hormone. It is completely consistent with the structure and function of gibberellic acid in plants. Choline chloride is a B vitamin widely used in agriculture, aquaculture and aquatic products, and it is also a non-toxic substance. 6-benzylaminopurine and chlorfenuron are chemicalSynthetic regulator. These substances are non-toxic or low-toxic substances. They are used during the fruit expansion period. It takes a long time for ripening and harvesting, so there is basically no residue in the fruit.
Can expansin be used?
Swelling hormone is a plant growth regulator. In 1997, the “Pesticide Management Regulations” formulated by the Ministry of Agriculture classified plant growth regulators as pesticides. At present, there are more than 100 kinds of plant growth regulators registered and used in various countries in the world, which are used to regulate the growth and development of crops. The Ministry of Agriculture of China adopts the pesticide safety evaluation standards and methods of the Food and Agriculture Organization and the World Health Organization to scientifically test and evaluate the plant growth regulators applying for registration. Since 2015, the Ministry of Agriculture and Rural Affairs has conducted a risk-friendly resource*** assessment of plant growth regulator residues in agricultural products. The results showed that the average residual amount of plant growth regulators was only 0.001 ~ 0.034 mg/kg, which proved that the quality and safety of agricultural products were guaranteed and would not affect the quality of agricultural products.
In agricultural production, due to the influence of environment, temperature, humidity, management and other aspects, the endogenous hormones of plants are often out of balance. Once the plant growth is out of balance, a large number of flowers and fruits will drop, causing a huge loss in yield. Plant growth regulators must be used to increase yield, improve quality or prolong supply and save labor. For example, if bananas are picked to full maturity, they cannot be transported long distances and will rot. Therefore, bananas cannot be eaten in northern China.
Misunderstood causes of swelling.
The key to the misunderstanding is that consumers do not know enough about plant growth regulators, coupled with the exaggerated publicity of some media, causing consumers to see the word “swollen” and feel fear in their hearts. In the next step, the Ministry of Agriculture and Rural Affairs will continue to strengthen science popularization, strengthen technical training and guidance, popularize the knowledge of plant growth regulators, and improve farmers’ and consumers’ awareness of growth regulators.
