西澳大利亚大学农学系E.G.Barrett-Lennard博士、付教授H.Greenway与A.D.Robson博士最近发表了一种诊断植物轻度营养缺乏的新的生化方法,可以对小麦缺磷提供可靠依据。在联合王国苏塞克斯温室研究所工作的R.T.Besford博士于1977年提过一种建议,即磷酸酶有可能用作植株缺磷的生化标记。他发现,蕃茄缺磷时,叶中磷酸酶的含量就急剧增加。于是,西澳大利亚农学专家三人小组着手评价这种酶对确诊小麦缺磷的潜在
E.G. Barrett-Lennard, Ph.D., Ph.D., H.Greenway and A.D. Robson, Ph.D., Department of Agronomy, University of Western Australia recently published a new biochemical method for diagnosing plant mild nutritional deficiencies that could provide a reliable basis for phosphorus deficiency in wheat. Dr. R. Bisford, working at the Sussex Greenhouse Research Institute in the United Kingdom, made a suggestion in 1977 that phosphatases may be used as biochemical markers of phosphorus deficiency in plants. He found that the phosphatase content of the leaves increased sharply when tomatoes lacked phosphorus. As a result, a trio of Western Australian agronomy experts set out to assess the potential of this enzyme for the diagnosis of phosphorus deficiency in wheat
