Knowledge of boron mobility or immobility in various plant species is important in interpreting plant analysis results.
Boron is a micronutrient required for all plant nutrition. The main functions of boron relate to cell wall strength and development, cell division, fruit and seed development, sugar transport, and hormone development.
Plants initially may not exhibit obvious symptoms of boron deficiency. When moderate or severe boron deficiency occurs, most crops exhibit visible symptoms. Knowledge of boron deficiency symptoms can help in diagnosing deficiencies.
One of the important functions of boron in plant nutrition is its role in fostering pollen growth and development, which is important in seed set and the resulting fruit, nut and grain production.
