Histidine

1. Promote root growth

Crop root growth is completed by the continuous division and elongation of root tip. Cytokinin is an important hormone to promote root cell division. Histidine is a catalytic enzyme for cytokinin synthesis, which promotes the synthesis of cytokinin, thus stimulating the division and growth of root tip meristem cells, inducing the growth of adventitious roots, making seedlings root faster, main roots grow, lateral roots increase, and root length and volume increase, It is beneficial to the formation of root morphology.

Histidine is a natural metal chelating agent, which can chelate the insoluble medium and trace elements in the soil to form a chelate with good solubility and easy to be absorbed by crops, so as to prevent the elements from being fixed in the soil and plants, enhance the absorption and utilization of nutrients by the root system, and promote the growth of the root system.

2. Enhance drought resistance of crops

When crops are under drought conditions, if stomata are open, cells will be dehydrated or even die. Histidine is a component of histidine kinase substrate protein. The increase of histidine can increase the content of histidine kinase, which can participate in the signal transduction of abscisic acid induced stomatal closure. Under drought conditions, it can keep the stomata of crops closed, and reduce the amount of water lost by crops due to transpiration, Improve drought resistance of crops. Histidine can promote crop growth metabolism and nutrient absorption, and improve drought resistance.
