Abstract:加钙培养的小麦黄化苗和绿苗,经过红光(R)、远药光(FR)处理有效地提高谷氨酸合成酶(GOGAT)的活性。不同光质对麦苗硝态氮代谢关键酶活性的影响与细胞内钙调系统及其作用靶酶-Ca^2+-ATPase、H-ATPase活性有密切的联系。Ca^2+-ATPase、H-ATPase的作用能改变细胞内H、Ca^2+的浓度,从而调节细胞的内环境,进而对植物的代谢过程起调节作用

Abstract:以鄂南第四纪红色粘土发育的棕红壤为供试土壤,研究了大豆、芝麻、油菜、小麦、水稻、玉米等6 种作物的吸硼规律。建立的植物吸硼模型AP= TB·RE·AL能较好地反映作物吸硼规律。结果表明根系吸硼强度AL与作物生育期呈非线性关系,根系的吸硼强度因作物和生育期不同而有差距,6 种作物中以油菜、芝麻较强,不同生育进程中芝麻、油菜随时间推移吸硼强度加强,其它作物随时间推移吸硼强度减小。
