Distribution and partitioning of newly acquired boron (B) in a mature sunflower (Helianthus annuus L., cv. 3101) plant was investigated. In leaf blades of sunflower plants grown under 0.93, 2.8, and 9.3 mmol B m−3, the level of cell-wall-bound B was rather uniform, irrespective of leaf position and B concentration. Boron concentration gradients among leaf positions were produced mainly by different levels of water-soluble B. To determine the distribution of newly taken-up B in plant parts, 10B… CONTINUE READING
