Other claims from this paper (12)
- Observation NT–5 produced very little nicotine after more than 47 subcultures on OT–23 medium.
- Observation OMT–53 retained high nicotine production across 50 cultures.
- Association NT–5 and OMT–53 differed in growth response to α-NAA concentration.
- Intervention effect NT–5 produced no nicotine at any tested α-NAA concentration.
- Intervention effect OMT–53 produced abundant nicotine within a narrow α-NAA range, optimal at 0.15 ppm.
- Intervention effect NT–5 callus did not decompose added nicotine.
- Intervention effect OMT–53 callus did not decompose added nicotine.
- Intervention effect Moderate added nicotine did not affect OMT–53 nicotine production.
- Intervention effect Very high added nicotine appeared to considerably affect OMT–53 nicotine production.
- Intervention effect Added precursors had a slight positive effect in OMT–53 callus.
- Observation NT–5 had a much smaller total free amino acid pool than OMT–53.
- Observation Individual amino acid proportions were similar between NT–5 and OMT–53 callus.
