摘　　要：用不同浓度的巴巴安对科丰07玉米进行浸种处理并在幼苗期进行灌溉处理,观测玉米的种子萌发、茎粗、株高、真叶生长速度等形态指标和光合色素含量、硝酸还原酶活性等生理指标。结果表明,巴巴安可以有效地提高玉米种子的发芽率和发芽势,其中以200mg/L处理组的总体效果最为显著;巴巴安有利于玉米幼苗的生长发育,且形成显著性差异,也以200mg/L处理组最为突出;巴巴安有利于光合色素的增加,其中对叶绿素的作用最为明显,且200mg/L处理组表现最为突出;100mg/L处理组可以极显著地提高玉米硝酸还原酶活性,增强对硝态氮的利用能力。试验结果表明,巴巴安有利于玉米的种子萌发和幼苗的生长。In this experiment,Kefeng 07 maize were treated by seed soaking and irrigation treatments in seedling period with different concentrations of BaBaAn.We observed morphological indexes such as seed germination,stem diameter,plant height,euphylla growth rate and also physiological indexes like photosynthetic pigment content and nitrate reductase activity.The results showed：BaBaAn could effectively improve the germination rate and germination energy of the seed,especially the group of consistency of 200 mg/L,which shows the most significant overall effect;BaBaAn could promote the growth and development of maize seedling and showed significant difference;the 200 mg/L group has the best effect;BaBaAn could increase the photosynthetic pigments which was most obvious on the role of chlorophyll,and the 200 mg/L group was the most prominent;100 mg/L concentration could significantly improve nitrate reductase activity and enhance the capacity of using NO-3.The result indicated that BaBaAn could promote maize seed germination and seedling growth.
