The influence of the allelopathic compound ferulic acid (FA) on nitrogen uptake from solutions containing both NO(3) (-) and NH(4) (+) was examined in 8-day-old nitrogen-depleted corn (Zea mays L.) seedlings. Concurrent effects on uptake of Cl(-) and K(+) also were assessed. The presence of 250 micromolar FA inhibited the initial (0-1 hours) rate of NO(3) (-) uptake and also prevented development of the NO(3) (-)-inducible accelerated rate. The pattern of recovery when FA was removed was… CONTINUE READING
