Boron stress affects photosynthesis and metabolism of plant pigments. Stress due to the deficiency and toxicity of boron is common in crop plants. Currently, the role of boron in photosynthesis and its effects on pigment metabolism are unknown. Photosynthesis can present stomatal limitations due to a decrease in gas exchange and non-stomatal limitations, characterized by decreases in the activity of enzymes of the Calvin cycle and alterations in chlorophyll fluorescence deficiejcia to the decoupling generated between the photo phase and synthesis phase of photosynthesis, promoting contents that increase reactive oxygen species that negatively affect some molecules, cellular structures, and photosynthetic efficiency.

Likewise, an alteration of the pigment metabolism occurs, changing the composition of a, b, and total chlorophylls, as well as the concentration of other pigments, such as carotenoids, involved in the tolerance of plants to various stress conditions, varying their expression according to the species and phenological stage.
