It plays a fundamental role in biochemical and physiological processes in plants. One of the possible functions of manganese is the improvement of the plant’s defense system against diseases.
It increases plant resistance to diseases, by reinforcing the lignification of the cell wall, as it is directly involved in the production of lignin and suberin. It also regulates auxin levels in plant tissues, activating photosynthesis, especially photosynthesis II.
Applications of this nutrient boost the levels of photosynthesis and metabolic activities, increasing the competitive ability of plants, increasing their tolerance to diseases. It induces protective mechanisms and consequent increase in plant resistance.
Deficiency – Deficiency leads to decreased photosynthesis and productivity.
