A study on influence of different doses of Benzyl Adenine (BA) combined with constant level of Naphthalin acetic acid (NAA) on callus induction, shoot multiplication, and rooting of Kew pineapple was conducted. Early callus response was observed in treatment concentrations of 2mg/l BA with 2mg/l NAA and 3mg/l BA with 2mg/l NAA. Treatment 2mg/l BA with 2mg/l NAA was resulted to replicate the maximum number of shoots (22.71 at 90 days) significantly among the treatments. Shoot length was most enhanced by 0.5 mg/l BA with 2 mg/l NAA (8.09 cm at 90 days) dose. Shoots in control condition developed to be shorter in all the culture periods. On sub culturing in fresh and same media of all the treatments, root initiation was observed 30 days after culture. 0.1 mg/l BA with 2 mg/l NAA was found to be significantly efficient with the number (6.33 at 90 days) and length (2.08 cm at 90 days) of roots developed among the treatments. The plantlets were acclimatised at a satisfactory rate.
