Magnesium is transported from old leaves to young leaves, unlike calcium. Especially since the nutritional element in fruits is provided by floemiole, the K and Mg contents of the fruits are higher than their Ca content. Magnesium is effective in protein synthesis.
magnesium deficiency in plants
As the severity increases, symptoms may resemble leaf edge blight related to potassium deficiency. More characteristic of it is that the terminal shoots fade the green color of the old leaves by gradually developing between the veins towards the base of the main leaf vein and giving a fishbone-like appearance. In pears, development of dark and purplish tissue islets surrounded by stripes showing chlorosis effect can be seen in the intervascular areas. As the growing season progresses, symptoms begin to appear on young leaves and older leaves fall off.
The presence of large amounts of magnesium is not specific, but often appears to be similar to a potassium or calcium deficiency.
