The gibberellin biosynthesis inhibitor, ancymidol, was used during micropropagation of Hosta ‘Blue Vision’. Shoot growth and bud division was monitored every 2 weeks over an 8-week period in media containing 1 μM benzyladenine (BA) and various levels of ancymidol (0, 0.1, 0.32, 1 and 3.2 μM). Ancymidol prolonged bud division from 2 to 6 weeks and increased the total number of buds produced. Sho...
