Promotes early maturity. Affects flower set, fruiting quality, and yield. Necessary in conversion of carbohydrates into proteins. Boron affects root growth. It is essential for normal germination of pollen grains and the growth of pollen tubes.

Necessary in Chlorophyll formation and in photosynthesis and seed formation. Is a part of certain essential enzymes. Acts as a catalyst in certain carbohydrate and protein building reactions.

Plays a major role in production of Chlorophyll. Involved in respiration of plants. Serves as a catalyst in cell division and growth processes.

Aids in Chlorophyll formation: serves as a catalyst in enzyme reactions such as breakdown of carbohydrates, and Nitrogen transformation.

Necessary for module bacteria in fixing nitrogen from the air by legumes. Traces are needed to reduce Nitrate Nitrogen so that they can use Ammonium in protein formation.

Needed in protein formation. Influences consumption of sugar in the plant. Necessary for many enzyme reactions in plant, including the one forming one of the plant hormones.
