Objective: “Broad bean (Vicia faba) is important in many countries as a source of high protein percentage, amino acid ratios, mineral salts, and calcium. The use of new scientific methods and modified traditional methods such as plasma water have helped a lot to achieve of improved plant growth. This study was conducted to investigate the effect of plasma-activated water on growth and anatomical features of Vicia faba.

Method: After preparation , seeds were first soaked for 24 hours with water that had been activated with plasma for 5 minutes and 20 minutes, and with control water without plasma application. After planting, the pots were watered twice a week for 40 to 50 days. After this period, the anatomical features were examined.

Results: The results showed that in plants treated with vascular bundle dispersion, the growth and development of xylem vessels and the growth of the vegetative apical meristem were greater than in the control And the treated plants entered the reproductive phase faster.

Conclusions: plasma-activated water can increase the growth of faba bean plants by causing changes in anatomical and developmental characteristics.

According to the article results, use of plasma water is recommended to improve the performance of this plant.
