it is concluded that variation among plant species in the light requirement for nitrate and nitrite assimilation explains some of the contradictory results in the literature , but additional explanations must be sought to fully resolve the controversy.in dark anaerobic conditions , the assimilation of [ ( 15 ) n ] nitrate to ammonium and amino-n in leaves of wheat , corn , and soybean was 43 to 58 % of the dark aerobic rate while dark anaerobic assimilation of [ ( 15 ) n ] nitrite for the same species was 31 to 41 % of the dark aerobic rate .
