Abstract
Different developmental processes in plants are highly influenced by cytokinins.  On the other hand, recently light emitting diode has garnered much reputation in plant tissue culture system due to its high energy efficiency and versatility. In the present study the effective concentration of 6-benzylaminopurine (BAP) on the organogenesis of Oncidium Aloha ‘Iwanaga’ was assessed and further evaluated under different LEDs. From the initial experiment, 0.1mg/l BAP was found to be the optimum concentration among others in terms of the average number of PLBs/explant and other parameters. The highest number of PLBs (28.1/explant) and shoots (2.0/explant) was obtained using 0.1mg/l BAP. Regarding root formation no response was observed under the treatment applied. In case of the LED treatments with 0.1mg/l BAP, the trial indicated that the number of PLBs increased under white (28.1/explant) and blue (26.2/explant) LED. Maximum shoot regeneration and fresh weight were observed under white LED compared to control. So, a combination of 0.1mg/l BAP with white LED could be proposed to be suitable for in vitro regeneration of Oncidium Aloha ‘Iwanaga’.
