The MS medium supplemented with BAP and NAA showed different results
for leaf length, which was significantly influenced by different concentrations.
The longest leaves were produced by the concentration of 7.5 mgL-1 BAP + 0.5
mgL-1 NAA (0.85, 2.70, and 4.23 cm at 10, 20, and 30 DAI, respectively, which
was statistically significant. Statistically identical results was observed in 7.5
mgL-1 BAP + 1.0 mgL-1 NAA at 20 DAI (2.10 cm) and 30 DAI (3.70 cm).
Rahaman et al. (2004) observed the similar result. They obtained longest leaf in
the treatment 5.0 mgL-1 BAP (3.62 cm) followed by 1.5 mgL-1 NAA and 4.0
mgL-1 BAP (3.40 cm) using BARI Banana-I. They also found shortest leaf in 2.0
mgL-1 BAP. The results of present experiment agree with the findings of Khanam
et al. (1996) who obtained longest leaves in banana on MS medium
supplemented with 25 µM BAP treatments.
