Treatments M6 and M7. both of which contained BAP and , and which were on BM2 and BM3, respectively, produced a greater num- ber of shoots per explant than most BMl treatments containing combinations of L\A and kinetin. The mean weight of individual shoots cultured on the different media ranged from to grams per shoot. Few consistent differences were obsen-ed among the five BMl treatments. Compared to those treatnients. M6 (on BM2 with BAP and GA,) pro- duced shoots widi the greatest weight. Despite some differences among BMl treatments, the results show.
