Other claims from this paper (6)
- Intervention effect N-Methyl-N-nitrosourea inhibited tobacco tissue culture growth at 0.1 to 1 mM.
- Association Growth inhibition increased with mutagen concentration.
- Observation Primary pith slices and the three-year culture strain differed in sensitivity to the same mutagen concentrations.
- Intervention effect Prior culture fractionation reduced variability in inoculum sensitivity to mutagens.
- Intervention effect Standardizing inoculum age and size reduced variability in sensitivity to mutagens.
- Observation Relative growth-rate ratios suggest mutagen effects fluctuate during subculture and cultures may recover.
