In Vitro Multiplication And Plant Regeneration Of Red Banana (Musa Acuminata) Using Light-Emitting Diodes (Leds) System
(2025-03)
Bege, Jonathan
The red banana is a versatile plant with numerous nutritional benefits, agricultural potential and applications in food science and technology. Its special characteristics make it the subject of ongoing studies aimed at maximising its benefits and sustainability in a variety of industries. In the present study, the effects of different light spectra and plant growth regulators (pgrs) on the in vitro cultivation, physiological properties, genetic similarity and acclimatisation of musa acuminata cv. Red banana were investigated. The aim of the study was to improve shoot regeneration, growth indicators, root development and the successful transfer of plantlets to the field. In the first phase of the trial, thidiazuron (tdz) and 6-benzylaminopurine (bap) proved to be the most effective pgrs for promoting shoot formation, with tdz treatments resulting in the highest shoot regeneration rates. Tdz improved shoot multiplication but resulted in shorter shoot lengths than other pgrs. Indole-3-butyric acid (iba) was found to be most effective in root formation, with 1 μm significantly increasing root elongation. Naphthaleneacetic acid (naa) at 3 μm produced the largest average number of roots.
