Effect of source of nitrogen on growth, alkaliodal content and enzymes activities in Atropa acuminate
Effect of source of nitrogen on growth, alkaliodal content and enzymes activities in Atropa acuminate
M. Bashir Khan
ABSTRACT
Total biomass.Percentage of tropane alkaloids.Total
alkaloid per plant.Ornithine decarboxylase (ODC)
activity, arginine decarboxylase (ADC) activity,
arginine were determined separately in roots, stems and
leaves of Atropa acuminate fed with nutrient solution
having different source of nitrogen fertilizer. All
sources of nitrogen fertilizer increased the total
biomass and the highest increase (27.2% of control) was
in the plants fed with both ammonium and nitrate. The
highest increase (34.7% of control) in the alkaloid
concentration was in the plants fed with only
ammonium.The increase in the Putrescine level. ODC and
ADC activities was higher in the plants fed with only
ammonium of both ammonium and nitrate as compared to
those plants fed with only nitrate.
