| Abstract:
In order to learn more about the production parameters of different artichoke varieties, to determine critical moments in artichoke development and to predict yield evolution over the length of the season, inflorescence growth tests were performed every three days throughout the harvesting period on material of differing origins. The varieties under study were: Blanca de Tudela; INIA-A, INIA-D, ITGA, Clon 303 (Tudela clones); Cabeza de Gato (Tudela mutation); Moretto and Spinoso Sardo (Italian varieties); Camus de Bretagne and Violete Provenze-55 (French varieties); PAT-89 and PAT-97 (INIA-D in-vitro clones). The results shown here cover the 96-97, 97-98 and 98-99 seasons. Although differences between the three seasons were witnessed, a higher degree of earliness was observed in material with origin in the Blanca de Tudela variety, Moretto, C. Bretagne and PAT-89 proving to be the slowest varieties. The varieties with the greatest yields were Clon 303 (with 3.13, 4.39 and 2.91 kg/plant over the three seasons), INIA-D (3.12, 3.16 and 2.66 kg/plant) and Moretto (4.11, 3.29 and 2.89 kg/plant). These three varieties also gave the highest number of inflorescences per plant. Similar average inflorescence weights, never failing to break the 100-gram mark, were obtained for the three seasons, no significant differences being observed between varieties. The number of days between the appearance of the inflorescence and harvest (diameter of 60-65 mm) ranged from 20 to 31 days depending on the variety. In conclusion, the Blanca de Tudela variety and its clones should be highlighted for their high general levels of both earliness and yield when compared with the other varieties, Moretto being a slow variety which gives large yields at the end of the season. | |
