The importance of boron (B): It acts together with calcium in the regulation of the functioning of the membrane and cell wall, division and increase of cells, lignification of the cell wall, being essential for the formation of meristematic tissues.
It influences root development, nutrient absorption and pollen grain germination; participates in the metabolism and transport of carbohydrates through the formation of sugar-borate complexes, being important in the synthesis of proteins.
The symptoms of boron deficiency (B) appear initially with the yellowing of the leaves of the pointer; dark green concentric rings may appear on the petioles and stems, with internal necrosis of the medulla. There is also excessive fall of flower buds, flowers and even new fruits.
