Abstract
Summary Adventitious roots, shoots or both, and embryos were formed in apple, Malus pumita cvs Phiriki and Golden Delicious, embryonic tissues cultured under light and at 25°±2°C on modified Murashige and Skoog medium containing various growth regulators or combinations of them. Of the different parts of the embryo tissue, the petiole of the cotyledon was most responsive in morphogenesis. The initiation of shoots and roots was localized at the petiole of the cotyledon. Adventitious shoots, when transferred to the same medium containing 2 mg 1-1 IAA, rooted and formed plantlets. Embryos developed from the structures initiated mainly at the petiole of the cotyledon. The majority of these structures proliferated and formed callus, but a very few of them continued their growth as embryos after transfer to the same media containing no or a lower concentration of auxin.
