摘　　要：对植物生长调节剂在玉米抗逆性方面的研究和应用进行分析。结果表明,植物生长调节剂在提高玉米抗旱性方面应用最广。在水分胁迫下,植物生长调节剂可通过提高保护酶活性和渗透调节能力,扩大根系吸收面积,延缓叶绿素的降解等,增强玉米耐旱性,保证玉米高产稳产。The study and application of plant growth regulators maize tolerance was analyzed in this paper. The resuls showed that the plant growth regulators were most widely used in maize drought- tolerance. It could improve maize drought-tolerance and ensured its high and steady yield under water stress by improving protective enzyme activity and penetration regulation capability, expanding roots assimilation area and staving chlorophyll degradation.
