Ammonium Influence on the Growth and Nitrate Reductase Activity of Paul's Scarlet Rose Suspension Cultures

RESUMO
Suspension cultures of Paul's Scarlet rose were grown in two defined media which differed only in their inorganic nitrogen content. Both possessed equal amounts of NO3+ (24 mm), but differed in that NH4+ (0.91 mm) was present in control medium; whereas, no NH4+ was present in the test medium. A comparison of fresh weight increases over a 14-day growth period showed that NH4+ caused a 2-fold stimulation in growth and governed the pattern of development.
