Summary The evaluation of genetic variation and the release of virus-free cultivars are important in Vitis breeding. Sequential shoot tip cultures and high temperatures (32°, 35°, 38°C) were used to study their effects on the rate of shoot elongation during the proliferation phase (initial stage) of the in vitro culture in some Vitis vinifera cultivars. In the first culture the shoot elongation was more evident at 32°C than at 25° or 35°C; in addition at 35°C it was observed the shoot tip death in some cvs. while at 38°C in all cvs. In the sequential shoot tip cultures we noted a decline on shoot elongation and also an inhibition of shoot morphogenesis in the 4th and 5th recultures.
