The effects of low, regulated supplies of nitrate and ammonium nitrogen on the growth and composition of perennial ryegrass

Abstract

Perennial ryegrass was grown in flowing solution culture with nitrogen supplied in amounts that increased exponentially,i.e. in parallel with the rate of increase in growth. Nitrogen was supplied as either NO 3 − or NH 4 + , and the amounts to be added were calculated on the basis of extrapolated values for dry weights obtained from fitted curves. There… (More)
