Abstract
Foliar urea has been proved to act a better role in alleviation of the negative effects of drought stress (DS). However, the modulation mechanism of foliar urea are not conclusive in view of nitric oxide (NO) burst and glycinebetaine metabolism and their relationship. Two maize (Zea mays L.) cultivars (Zhengdan 958, JD958, Jundan 20, ZD20) were grown in hydroponic medium, which were treated with spraying of urea concentration of 15 g L-1 and two water regimes (non-stress and DS simulated by the addition of polyethylene glycol (PEG
