据西班牙Leidi,E.O.等人报道,金属酶活性作为营养状况的生化指标已研究30年,提出用酶活性作为缺乏微量元素的诊断指标。 作者测定了营养溶液中铁、锰浓度及比率,大豆叶中过氧化氢酶、过氧化酶、超氧化物歧化酶等金属酶的活性和大豆遗传型(品种)之间的关系,及其对大豆生长的影响。研究结果表明,铁、锰供应失调(不足或过量)都会影响金属酶的活性及大
According to reports by Spain’s Leidi, E.O. et al., Metalloenzyme activity has been studied for 30 years as a biochemical indicator of nutritional status and enzyme activity has been proposed as a diagnostic indicator of the lack of trace elements. The authors determined the relationship between iron and manganese concentrations and ratios in nutrient solution, the activities of catalase, peroxidase, superoxide dismutase and other metalloenzymes in soybean leaves and soybean genetic type (variety) The impact of growth. The results show that iron and manganese supply disorders (insufficient or excessive) will affect the activity of metal enzymes and large
