Abstract
The effect of three growth regulators, namely kinetin, 6 benzyl adenine, 2 chloro ethyl trimethyl ammonium chloride at three concentrations (10-6 M, 5 x 10-5 M 10-4 M) was studied on the catalytic activity of nitrate reductase in green and etiolated seedlings.A concentration of 5 x 10-5 M was optimal for all the growth regulators treatments.All the growth regulators stimulated nitrate reductase activity effectively at 5 x 10-5M concentration in both etiolated and green seedlings and had an additive effect when supplemented by NO-3 up to 140% to 160%.The 99.2% and 93.4% inhibition of nitrate reductase activity resulted in development of etiolated and green seedlings, respectively when treated with eukaryotic 80S ribosome protein synthesis inhibitor cycloheximide.Prokaryotic 70S inhibitor chloromphenicol did not have any effect on measured parameters.Actinomycin D, a RNA synthesis inhibitor also inhibited the enzyme activity as 80s inhibitors (Green 80%, etiolated 98%).One may suggest from this that both DNA and protein synthesis are involved in the induction of nitrate reductase activity.The differential effect of aminoacids was observed on enzyme activity in combination with growth regulators.
