Protoplasts isolated from callus cultures of the pericarp of Vitis vinifera cv.
Sultana regenerated cell walls within 3 days, when cultured in semi-solid media adjusted to 0.4 – 0.5 osmolal. Up to 12% of the cells divided during the next 7 days. A lower proportion passed through two division cycles.
