<p style="text-align: justify;">Two levels of leaf/area ratio were created for two varieties of grapevine (<em>Vitis vinifera</em> L.) in a glasshouse. Carbohydrate and free amino acids concentrations in the pruning wood were significantly reduced when the leaf/fruit ratio was low. In the following season, growth parameters were affected as well as yield components such as the number of shoots per plant, the number of inflorescences per shoot, the number of flowers per inflorescence and the number of berries per cluster. Fruit set was however not altered. Weight of grapes at fruit set was reduced by 68% for Gewurztraminer and by 46 % for Pinot noir.</p>

Proline-U-14C injected into the endosperm of 3-day-old etiolated seedlings of Montcalm barley and its mutant was readily translocated to the embryo. Of label present in the embryo, over 65% was accounted for by protein and free amino acids and about 25% was present in organic acids. Proline accounted for over 90% of the label in free amino acids of the endosperm but accounted for less than 50% of label in this fraction in the embryo. Proline was readily converted to glutamate in the embryo. Metabolism of proline was similar in both lines.
