Diagnostics of boron deficiency for plants in reference to boron concentration in the soil solution  

Boron in plants: deficiency and toxicity.

Boron (B) is an essential nutrient for normal growth of higher plants, and B availability in soil and irrigation water is an important determinant of agricultural production. To date, a primordial function of B is undoubtedly its structural role in the cell wall; however, there is increasing evidence for a possible role of B in other processes such as the maintenance of plasma membrane function...

Boron deficiency in woody plants: various responses and tolerance mechanisms

Boron (B) is an essential microelement for higher plants, and its deficiency is widespread around the world and constrains the productivity of both agriculture and forestry. In the last two decades, numerous studies on model or herbaceous plants have contributed greatly to our understanding of the complex network of B-deficiency responses and mechanisms for tolerance. In woody plants, however, ...

Effects of Boron Deficiency and Excess on Plants.

Influence of Soil Solution Salinity on Boron Adsorption by Soils

Boron (B) adsorption on two arid-zone soils from the San Joaquin Valley of California was investigated as a function of equilibrium solution B concentration (0–250 mg L), solution pH (3–12), and electrical conductivity (EC, 0.3 or 7.8 dS m). Boron adsorption on both soils increased with increasing pH, reached a maximum near pH 9, and decreased with further increases in pH. Boron adsorption as a...
