DENDROLOGY

Detailed explanation-1: -One of the first signs of magnesium deficiency is chlorosis. Chlorosis is the yellowing of the leaf structure found between veins, giving the leaf a marbled appearance, while the veins remain green. Another indication of chlorosis is for the leaf margins to turn a red-brown-purple colour.

Detailed explanation-2: -Magnesium is the central core of the chlorophyll molecule in plant tissue. Thus, if Mg is deficient, the shortage of chlorophyll results in poor and stunted plant growth.

Detailed explanation-3: -Description. Chlorosis is a yellowing of leaf tissue due to a lack of chlorophyll. Possible causes of chlorosis include poor drainage, damaged roots, compacted roots, high alkalinity, and nutrient deficiencies in the plant.
