Abstract
Solutions of L-[guanido- 14c]arginine hydrochloride and L-[U-l4C]asparagine were applied to dormant 2-year-old peach trees using a cut-shoot technique. Radioactivity was recovered in soluble sugar plus acid and protein amino acid fractions indicating that both compounds were metabolized by the trees. The results also suggest that there was a turnover of arginine in the dormant tissues. Most of the applied 14C from both compounds remained in the treated shoot or neighboring tissues, but small amounts were translocated both upwards and downwards from the point of application.Keywords
