[Intensification of the initial stage of amino acid metabolism in germinating cereal seeds by exogenous glutamine and proline].
The initial stage of amino acid metabolism was intensified in germinating wheat seeds with exogenous glutamine and proline. Exogenous glutamine and proline accumulated over 2 h at 4 degrees C in swelling seeds were spent at different rates over the following 2 h at 20 degrees C, thus compensating for insufficiency of these amino acids during the initial stage of development. Creation of an additional store of glutamine and proline during the initial stage of amino acid metabolism had positive effects on the seed germination and vital activity of the plants.
