Summary
The results of experiments on the possible source(s) of ammonia for the mung bean are reported. Different nitrogenous metabolites were fed to primary leaves of mung bean seedlings with and without methionine sulphoximine (MSO), an inhibitor of glutamine synthetase (GS). Their role in foliar ammonia loss is discussed.
