Boron is one of the most essential trace elements for the plant, important for its many metabolic processes.
Boron sufficiency is necessary during the reproductive phase of plants (blooming, fertilization, fruit setting,
seed and fruit growth, boron affects the fertilization of the flowers because it increases the number and
vitality of the pollens.) In the event of limited availability of boron, of the pollen tube.
After fertilization, boron affects embryogenesis and therefore lack of boron contributes to poor growth or
even degeneration of the embryos, resulting in the formation of malformed fruits. Thus, boron fever during
critical reproductive stages causes a significant reduction in production
One of the major roles of boron is structural, as a component of emerging plant tissues, and its lack leads
to the formation of structurally altered cell walls.
Boron plays an important role in the transport of sugars from one plant site to another due to its ability to
form stable complexes with them, while at the same time increasing the resistance of crop plants to low
temperatures due to its positive effect on carbohydrate metabolism and of proteins.
