Abstract
Nitrate uptake into intact pea seedlings (Pisum sativum L. cv. Feltham First) grown in hydroponic culture has been investigated. Following inoculation with Rhizobium leguminosarum a twofold increase in net nitrate uptake was observed. Changes in morphological characteristics following inoculation were found to decrease the effective area available for absorption. There was a two-fold decrease in net nitrate uptake into intact seedlings grown in the presence of N compared with N free media. In the former case net nitrate uptake appeared to stall at regular intervals. In both cases only the initial rates of nitrate uptake were found to be responsive to the external nitrate concentration. The results are discussed in terms of current models for the regulation of NO−3 uptake by higher plants.
