Of the target plant, the plant growth regulator is a non-nutritive exogenous chemical substance, usually conduction to the site of action in plants growth regulators, very low concentrations can promote or inhibit certain aspects of their life processes, to make it consistent with the development of human needs. Each plant growth regulator has a specific purpose, and application of very strict technical requirements, only to produce a particular effect on the target plant under certain application conditions (including external factors). Often changing the concentration will get the opposite result, for example, promoted at low concentrations, whereas at high concentrations it becomes inhibited. Plant growth regulators have many uses, because the target plant species and different. For example: control germination and dormancy; promote rooting; promote cell elongation and division; lateral buds or tiller control; control plant type (stocky anti-lodging); control flowering or growth regulators male gender role, inducing childless fruit; sparse sparse flowers If price growth regulators, control fruit drop; controlling fruit shape or maturity; enhance the resistance (resistance to disease, drought, salt points, antifreeze); the ability to enhance the absorption of fertilizers; increase sugar or alter acidity; to improve the flavor and color; promote secretion of latex or resin; defoliants or reminders estimate (facilitate mechanical harvesting); preservation. Some plant growth regulator used in a high concentration becomes herbicides, and some herbicides at low concentrations also have growth regulating effects. Plant growth regulators are not nutrient for plant growth regulator, can only play a role in the regulation of growth, not a substitute for fertilizer, water and fertilizer conditions are not sufficient in the case of spraying excessive plant growth regulator but harmful. Therefore, when the discovery of poor plant growth, we must first strengthen management fertilization watering, use on the basis of growth regulators to effectively play its role. The role of growth regulators, San Gil chemicals (certified), growth regulators provided by Zhengzhou Chemical Co., San Gil. San Gil Zhengzhou Chemical Co. (www.sjehg.com) is Zhengzhou, plant growth regulators leaders, over the years, the company implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. In San Gil Chemical leadership with the staff warmly welcome all inquiries negotiations to create a better future for San Gil chemicals.
