Abstract
Canes of 'Carignane' grapevines were collected on October 20 and thereafter at intervals through February 9. Cuttings from the apical, middle, and basal portions of the canes were immediately placed with their bases in water under conditions favorable for growth. With the first 3 collections, middle cuttings broke more rapidly than basal or apical cuttings. In canes collected on December 15 and thereafter, however, basal and middle cuttings broke more rapidly than apical cuttings. When basal cuttings were compared, the first two samplings had the slowest budbreak. Budbreak was generally most rapid in the February 9 collection. Rooting was usually best with basal cuttings and poorest with apical cuttings, regardless of date of collection.
