Physiological studies on stem growth and gummosis in tulips(cvs. Gudoshnik and Apeldoorn) were carried out, and following results were obtained.(1) Shoot growth of fully cooled tulip bulbs grown continuous dark conditions was investigated in relation to the role of applied auxin, suggesting that auxin is a major factor responsible for growth of all internodes in etiolated tulip stems.(2) Inhibitor of auxin polar transport, 2, 3, 5-triiodobenzoic acid(TIBA), was applied to uncooled tulip bulbs before flower bud formation at beginning of July and after flower bud formation in October and November. Shoot growth and flowering of partially dry-cooled bulbs were substantially stimulated, suggesting that TIBA partially replaces the cold requirement of tulip bulbs. The effect of TIBA is similar to that of gibberellins applied exogenously to the bulbs.(3) Simultaneous application of methyl jasmonate with gibberellin increased gum formation in tulip bulbs. Seasonal changes in gum formation were also demonstrated.
