| Abstract:
The aim of this study was to know the earliness and yield of different cultivar of artichoke after GA3 application as a substitute of vernalization, as soon as planting distance answer. The possible infection with tomato spotted wilt virus (TSWV) also was considered. Two seed propagated cultivar (Lorca, A-106) and another one of vegetative propagation “Blanca de Tudela” were tried. The results show that GA3 treatments, especially 25 ppm dose, are very effective to promote earliness in “Blanca de Tudela” cultivar, whereas the action was smaller in seed propagated cultivars. The increase of planting distance raised earliness of cv. Blanca de Tudela, whereas the effect was smaller in Lorca and A-106 cultivars. In the trial conditions cv. A-106 was the most sensible to TSWV disease. | |
