Abstract
The absorption and assimilation patterns of 15NO3− supplied as the Ca2+ and Mg2+ salts to intact ryegrass (Lolium perenne) seedlings were compared. No statistically significant effect of ambient cation on the amounts of 15NO3− absorbed was observed in the initial six hours, but during the subsequent six hours, absorption from Ca(15NO3)2 exceeded that from Mg (15NO3)2.Keywords
