Nitrogenase-dependent acetylene reduction activity of glasshouse-grown alfalfa (Medicago sativa L.) decreased rapidly in response both to harvesting (80% shoot removal) and applied NO(3) (-) at 40 and 80 kilograms N per hectare. Acetylene reduction activity of harvested plants grown on 0 kilogram N per hectare began to recover by day 15 as shoot regrowth became significant. In contrast, acetylene reduction activity of all plants treated with 80 kilograms NO(3) (-)-N per hectare and harvested… CONTINUE READING
