functions of calcium in plants
In general, plants with high root cation exchange capacity receive more Ca than plants with low root cation exchange capacity. There is more calcium in the cell walls. The main reason for this is that there are many calcium binding sites in the cell walls and the movement of calcium in the cytoplasm is limited. Calcium affects root elongation and cell division in plants. Calcium causes an increase in root secretion and an increase in a-amylase enzyme activity that plays a role in the germination of wheat germ. It strengthens cell membranes by bridging the carboxyl and phosphate groups of phospholophoids and proteins.
Calsium deficiency in plants
Certain deficiency symptoms due to calcium deficiency in orchards are very rare. More common symptoms are caused by high levels of other nutrients. If there is a deficiency, it first occurs when the edges of the leaves in young leaves are folded upwards in the form of a container and somehow chlorosis occurs between the veins. Even if there is sufficient calcium in the leaves, low calcium levels in fruits often cause symptoms (Bitter Pit, Corking).
