Effects of Plant Growth Regulators and Sugars on Ehretia asperula Zoll. et Mor. Cell Cultures
First Online 25-02-2021|
Methods: Samples of Xa den were less than two years old. Young stems with 2 to 6 leaves served as explants for callus induction. Explants placed on autoclaved B5 nutrients incubated at 25oC, in the dark. The testing factors were concentrations of 2,4-Dichlorophenoxyacetic acid (2,4-D) and Benzyl adenine (BA), types and concentrations of sugars.
Result: Friable callus was induced on B5 medium with 0.4 mg/L of 2,4-D, 0.1 mg/L of BA and 30 g/L of glucose at the highest rate (100%). Additionally, callus grew best after 5 weeks of culture weighing 0.194 g. Friable callus was used as material for cell suspension cultures. After two weeks, the Xa den cell suspension cultures contained single cells and small cell clumps. The liquid medium had changed from dark yellow to light brown.
