Calcium is present in plants in quite high quantities, localized in the cell walls and on the outer surface of the plasma membrane, calcium is indispensable for the cell division and stretching and if absent, the radical growth is quickly inhibited. This element intervenes in the activation of various enzymes and delays the foliar senescence. Calcium, moreover, helps the germination, the pollen formation and the radical development, it can also neutralize some toxic organic acids produced by the plant while breathing.
Boron is a basic microelement for plants as it stimulates their vegetative development through the cells division, helping the synthesis of the nucleic acids. Moreover, it develops an essential role in the chlorophyll synthesis as well as in the production and transport of sugars. In flowers biology, boron helps the fecundation to increase the germinability of the pollen and the activity of the pollen-tube, reduces the early drop and increase the formation and quality of fruits.

2. Deficiency Calcium/Boron
The calcium deficiency breaks out with the reduction of the growth of the vegetative apex and the youngest leaves, which can show also necrosis and curls or deformations. The deficiency breaks out, also, with the dissolution of the cell walls of fruits and back-up organs, whose tissues become soft and marcescent. In some vegetal species, the deficiency is very frequent and appears with necrotic spots (ie.: bitter apple-scab) and apex rot (such as, tomato) Calcium is almost motionless inside the vegetal tissues, very quick growths of plants, excessive fertilizations with ammoniac nitrogen and hard rains can enhance its deficiency.
Boron deficiency caused acute problems during flower fecundation and increase the early drop of the small fruits. During growing sprouts, it determines the shortening of the internodes and the emission of less resistant and asymmetrical leaves. In the most acute cases, in the fruit trees, it involves the bifurcation of the sprout and the death of the terminal bud with consequent emission of secondary sprouts, which make the plant look shrubbier, fruits are damaged by evident necrosis, cracks and splits. In the tuber cultivations, the deficiency breaks out with the gradual blackening of tubers and tap-roots in their inner part.
