MICROPROPAGATION OF THE SILK TASSEL BUSH, GARRYA-ELLIPTICA DOUGL

Proliferating cultures of Garrya elliptica were established from shoot tip and nodal explants grown on woody plant medium containing benzyla denine. Optimum numbers of healthy shoots were induced on media contai ning 1.25 mu M benzyladenine; higher concentrations caused more hyperh ydricity and less extension. Following growth for 28 days on quarter-s trength woody plant medium containing 0.2% activated charcoal, 90% of shoots rooted on the same medium lacking charcoal, but with 2.5 mu M i ndolebutyric acid. Survival during weaning was poor, and was strongly correlated with the time of year at which plants were removed from cul ture.
