Boron is an essential trace element in the metabolism of plants. It is involved in the absorption and metabolism of calcium, which is accumulated in the cell wall, joining pectins and conferring elasticity and toughness to the tissues.
Boron plays an important role in cell division and, therefore, growth. It is also involved in carbohydrate metabolism. Boron availability decreases in soils with a pH greater than 7 due to losses in mobility. In acidic soils of sandy texture boron is lost by being easily washed out of the floor. Its deficiency causes poor growth performance and reduced fruit quality.
