Reduktaza azotanowa siewek pszenzyta ozimego

Abstract

Nitrite reductase (NiR) was extracted from seedlings of winter triticale cultivar Moreno in the form of homogenous protein fraction with molecular weight of about 61 kDa, characterised by maximum of absorption at 280 and 390 nm. Differences in specific activity of enzyme isolated from plants cultivated in different conditions (garden soil, Hoagland's diet) suggest that NiR may be induced by light and nitrate ions presence in arable medium
