Résumé du colloque

Sequential changes in the alcohol soluble amino acid and amine fractions of vernalized and control root tips of Marquis (Spring) and Rideau (Winter) wheats have been followed. Substantial changes in these fractions can be related to developmental changes in the root tip. Vernalization superimposed additional, consistent, changes in the content of aspartic and glutamic acids, proline, glycine, alanine, valine, leucine, isoleucine and the amines, glutamine and asparagine. Incorporation studies using [14-C]-glutamic and aspartic acids served to emphasize the distinct metabolic differences between the "mitotic" and elongating regions of the root tip.
