Abstract

Occurrence and recovery of vitrification in tissue cultures of Paulownia species.

Abstract

Results are reported from a study of some factors which affect vitrification in tissue cultures, and a method for overcoming vitrification is proposed. Adventitious buds from internodal explants of Paulownia fortunei, P. kawakamii, P. tomentosa and P. taiwaniana were studied. Occurrence of vitrification varied between species. Vitrified shoots reverted to normal growth when subcultured on MS medium solidified with 0.8% Difco agar.
