| Sumario: | European grape varieties are efficiently micropropagated through single node
cuttings in modified Galzy medium (GM). On the contrary, the "criollas" varieties have not performed well in this medium. The purpose of this work was to evaluate the "criollas" varieties Cereza, Criolla Chica, Criolla Grande, Pedro Giménez and Torrontés Riojano, in full and half strength modified Galzy (GM)
and Murashige-Skoog (MS) solid and liquid media. Paper bridges and vegetal sponge were evaluated in liquid media. Nodal segments and shoot tips were used as initial explant. In solid media, differences in survival were found between varieties but explant type did not affect this variable. Plants from shoot tips and both explants in MS ½ grew significantly more than in the rest of the
treatments. In liquid medium, vegetal sponge was detrimental for both explants. With paper bridge support the best result was obtained with shoot tips cultured in ½ MS. The results suggest that the best medium for the micropropagation of "criollas" grape varieties from both explants is solid MS ½ medium. |
