Abstract

The acute γ-irradiation (0, 20, 30, 40 Gy) of two white wine grape varieties, Trebbiano Romagnolo and Albana, during in vitro proliferation was tested. Trebbiano R. had a higher in vitro proliferation rate, but also showed a higher number of cultures with vitrification and morphological abnormalities. Albana withstood a maximum dose of 30 Gy, while Trebbiano R. withstood the highest dose used
Among the field planted vines, variants with shorter internodes were found in the first 2 years after planting.
