Seven different hormone treatments, namely 6-benzylaminopurine (BAP) at 2, 3 mg L(-1) was applied singly and in combination with Indole Acetic Acid (IAA) at 0.18, 0.8 and 1.8 mg L(-l), BAP at 3.3 mg L(-l) in combination with IAA at 1.8 and 3.3 mg L(-l) and triple combination of BAP at 2.3, IAA at 1.8 and Gibberellic acid (GA3) at 1.0 mg L(-1) were tested, over four different incubation periods of 30, 45, 60 and 75 days, for their effect in the proliferation and growth of Smooth cayenne pineapple shoot-tip culture. Combined application of BAP at 3.3 and IAA at 1.8 mg L(-1) induced the highest proliferation of 19 shoots/explant and the highest total of 121 and 125 shoots over 4 cycles of multiplication. Raising the IAA to 3.3 mg L(-1) resulted in the lowest proliferation and stunted shoots. Incorporation of GA3 improved the shoot length but caused drastic reduction in proliferation. The other treatments showed an intermediate effect.
