Ammonium (NH(4) (+)) nutrition inhibits water uptake and root exudation and decreases leaf water potential of tomato plants grown in solution culture. This inhibition is readily reversible by NO(3) (-) for short term exposures to NH(4) (+); however, recovery is delayed following long term exposures.
铵(NH(4) (+))营养会抑制水的吸收和根系分泌物的排放,并降低在营养液中生长的番茄植株的叶片水势。这种抑制作用在短期暴露于 NH(4) (+) 时很容易被 NO(3) (-) 逆转;然而,在长期暴露后,恢复会延迟。
