In vitro propagation of Oryza sativa (MRIA 1) using different rate of benzylaminopurine (BAP) and naphthalene acetic acid (NAA) hormone / Rosmahani Yusuf

This research was conducted to produce in vitro regeneration of MRIA 1 and the best concentration of BAP and NAA hormone which produce the best shoot and root growth can be determined. The treatment used were 0.0 mg/l of BAP and NAA, 0.25 mg/l BAP + 1.0 mg/I NAA, 0.50 mg/I BAP + 1.50 mg/l NAA, 0.75 mg/l BAP + 1.75 mg/l NAA, 1.00 mg/l BAP + 2.00 mg/l NAA, and 1.50 mg/l BAP + 2.25 mg/l NAA. Based on the research it can be conclude that the best concentration of hormone which produce the best growth of shoot and root is 0.25 mg/l BAP AND 1.00 mg/l NAA.
