【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。更多还原

【Abstract】 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.更多还原
