function of zinc in plants
Occurs in eroded soils. Zinc intake is at the lowest level in 5.5-7.0 pH environment. At low pH, it causes intake at the toxicity point. Plants actively take up zinc in water-soluble form. Zinc solubility in soil is inversely proportional to soil pH. As the pH increases, the solubility decreases. The lower the pH, the higher the solubility. There is competition between zinc intake and copper, iron, manganese and calcium intake. Within the plant, zinc is carried by the xylem tissues in the form of Zn2 + ions or depending on organic acids. Although limited, there is a transfer from old leaves to young leaves. There is an antagonistic effect between phosphorus and zinc in plants. Some elements slow down the absorption of others by plants. For example, calcium slows down your potassium intake or the other one. This phenomenon is known as “antagonism”.
zinc deficiency in plants
occurs mostly in neutral or alkaline soils rich in phosphorus and carbohydrate content. Zinc deficiency affects the roots rather in cultivated plants and causes the death of old root tissues. On the other hand, in zinc deficiency, chlorosis occurs between leaf veins. While the leaf veins remain green, the color between the veins turns light green, yellow or even white. Symptoms are defined as rosettes or small leaves. Newly developing leaves are smaller than normal. Since the shoot development is short, the leaves are close to each other and give a rosette appearance.
In severe cases, old leaves may fall off. In the early spring, a delay in green parts can be noticed in the lateral leaves of the last year. These symptoms can be confused as cold damage, but the distinctive feature of cold damage is a browning in the cambium tissue. Leaf edges sometimes become wavy. Yellow mosaic spots occur between the veins on the leaf surface, with the vein edges remaining green. If the deficiency is not severe, it only affects the leaves.
