Effects of Growth Regulators and Gelling Agents on Ex Vitro Rooting of Raspberry.

Successful acclimatization and ex vitro rooting are among the key factors reducing the cost of micropropagated plants. We compared the survival of seven Russian cultivars of raspberry () after rooting in vitro and ex vitro. Rooted shoots adapted to nonsterile conditions much better than nonrooted ones, with survival rates of 81%⁻98% versus 43%⁻76%, respectively.
