Abstract
THERE have been numerous reports of interactions between amino-acids in their effects on the growth of bacteria and fungi, while relatively few interactions of this type have been reported in studies with higher plants. Mixtures of amino-acids have been found to interact in their effects on the growth of immature Datura embryos1. Antagonisms have been reported between canavanine and structurally related amino-acids in their effects on the growth of Avena coleoptile sections2 and immature embryos of maize3. Experiments reported here extend these observations in so far as they expose a series of interactions between amino-acids in their effects on the growth of mature embryos of oat. These interactions have been observed as antagonisms between individual amino-acids in their effects on root growth.
