摘 要 ：人工控制条件下生长的小麦、玉米分别培养在含0、0.5、1.0和2.0mM SO_4~(-2)4个硫营养水平的Hoagland 培养液中,对2—6周龄的植株进行了 RuBPCase、PEPCase、NR 的活性,叶片可溶性蛋白质含量,叶绿素 a 和 b 含量以及植株最终叶面积和总干重的测定。结果指出,硫营养不足影响了作物的碳、氮代谢,随着供硫量的增加,上述各参数值

Abstract:Wheat and maize seedlings were grown in controlled environment growth chamber.The hydroponic system with 0,0.5,1.0 and 2.0 mM SO_4~(-2)in the modified Hoagland‘s so-lution was used for plant growth.RuBPCase,PEPCase and NR activities,Chl.contentand soluble protein content in leaves were measured when
