| Abstract: | Changes in the concentrations of NH4+ and amides during the growth of suspension cultures of rose (Rosa cv. Paul's Scarlet) cells were examined. When cells were grown in medium possessing only NO3− as a nitrogen source, the concentrations of NH4+ and amides increased to 4.0 × 10−1 and 5.9 micromoles per gram fresh weight, respectively. The amounts of both constituents declined during the later stages of growth. When a trace amount of NH4+ was added to the NO3− base starting medium, the concentration of NH4+ in the cells was increased to 7.0 × 10−1 micromoles per gram fresh weight. |
