The effects of sucrose, activated charcoal, and coconut dust on in vitro corm induction of Gladiolus hybrida under aseptic technique

Sucrose, Activated charcoal, Coconut dust, Gladiolus hybridaบทคัดย่อ
This study aimed to investigate the effect of sucrose concentrations: of 3%, 6%, and 9% together with or without two different supplementary matters: activated charcoal (0.01%) and coconut dust (10%) on in vitro growth and corm induction of Gladiolus hybrida when cultured for 5 weeks. The objective was to investigate the optimal culture media for corm production in long-term culture. The results showed that shoots grown on MS medium with the addition of 10% coconut dust at any sucrose concentrations had a high percentage of corm induction, ranging from 72 to 88. The treatment of 6% sucrose supplemented with 0.01% activated charcoal and 10% coconut dust yielded the highest corm induction percentage (88%) after being cultured for 5 months. Therefore, the optimum medium for corm induction of Gladiolus hybrida was MS medium supplemented with 6% sucrose, 0.01% activated charcoal, and 10% coconut dust.
