Nodulated plants of white clover (Trifolium repens) were established on agar slopes and then grown in batch nutrient solution. The solution contained various levels of phosphorus (P). The nodules were strong sinks for P when the supply was low, the concentrations of P in the nodules being higher than in the roots and shoots. At higher P levels, the roots and shoots came to have P concentrations equal to or higher than the nodules. The percentage of (N) in the plant parts and the activity (N fixed per unit nodule weight) of the nodules was unaffected by P supply. As the P concentration in the nodules increased with supply, their efficiency in terms of N fixed per unit of nodule P declined. It appears as if not all nodule P may be involved in N fixation, in a manner analogous to the decline in efficiency of use of P for growth as the supply increases. |
