Abstract
The effects of seven levels of molybdenum (Mo) supply on growth, distribution and redistribution of Mo in black gram cv. Regur on a Mo deficient acid soil were examined in a glasshouse experiment. Seed of Mo concentration 17 4 Mg Mo/g dry matter was used. At the three lowest Mo rates, plants showed N deficiency symptoms typically induced by low Mo supply in legumes. Nitrogen deficiency symptoms depressed whole shoot dry matter. Increasing the Mo supply increased Mo concentrations in all plant parts. In the leaf blades of plants at all growth stages, the increases were smaller over the three lowest rates of Mo supply: further increases in the Mo supply markedly increased the concentrations of Mo in all leaves, particularly in the recently matured leafblades (YFELb and YFEL-1 b). In addition, in petioles, the concentrations of Mo exceeded those in the blades which they supported at all levels of Mo supply. In Mo-adequate plants, the concentrations of Mo were higher in the stems than in the petioles and higher in the -petioles than in the blades. Molybdenum concentrations in the nodules were higher than in the above ground plant parts except at the high levels of Mo supply where the concentrations in the basal stem exceeded those in the nodules. The mobility of Mo in the phloem appeared to vary with plant parts and the Mo supply. For example, in Mo-adequate plants, there was no net loss of Mo.
