Efecto de la intensidad de la poda en el desarrollo in vitro de embriones de vides estenospermocárpicas Effect of pruning intensity on in vitro development of embryos from stenospermocarpic grapes

The embryo rescue technique allows obtaining plants by crossing seedless cultivars, however the number of plantlets obtained is low. The aim of this work was to evaluate the effect of pruning intensity on in vitro embryo development in two stenospermocarpic cultivars (Emperatriz and Fantasy Seedless) and to correlate the embryo performance with different traits. Differences were observed between cultivars. In cv. Fantasy S. the number of plantlets obtained increased while decreasing intensity of pruning.
