玉米(Zea Mays L.)杂交种豫玉3号在孕穗期采用叶面喷施:0.5％ KH_2PO_4、0.01％“叶面宝”、0.1％“爱农”、0.4％“微肥”和蒸馏水。开花期在水分胁迫下,与未受水分胁迫的植株(CK)相比,叶水势和相对含水量降低,质膜透性增大,脂质过氧化作用增强,叶组织膜脂脂肪酸组分发生改变,最终导致产量降低。但经过生长调节剂处理的植株,耐旱性增强,叶片受伤害程度较轻,产量损失较小。
Maize (Zea Mays L.) hybrid Yuyu 3 booting at the booting stage: 0.5% KH_2PO_4, 0.01% “foliar”, 0.1% “love”, 0.4% “micronutrient” and distilled water. Flowering stage under water stress, compared with CK without water stress, leaf water potential and relative water content decreased, plasma membrane permeability increased, lipid peroxidation increased, leaf tissue fatty acid composition occurred Change, eventually leading to lower production. However, the plants treated with growth regulators increased their drought tolerance, less damage to the leaves and less yield loss.
