Translocation of Boron to Plant Fruits

Abstract

Fruit of peanut (Arachis hypogaea L.) and burrs of subterranean clover (Trifolium subterraneaum L.) were shown to develop in white siliceous sand which was low in boron. Fruit and seed production and yield did not vary with the boron nutrition given to the medium in which seeds developed. The results suggest that for the development of their fruits, peanut and subterranean clover translocate boron in their phloem.
