用电子显微镜观察了正常（营养充足）的番茄、菠菜和玉米植株的叶片细胞，以及除氯外缺乏每种已知的必需宏量和微量营养素的植株的叶片细胞。在菠菜的情况下，观察也进行了相衬和荧光显微镜。本研究的一个特点是在营养充足和缺乏矿物质的植物中，叶绿体切片的形状、大小和外观都有很大的差异。本文提供了一系列具有代表性的照片来显示这种变化。在锰和铁缺乏的情况下，叶绿体外观发生了特殊的变化，在其他10种缺乏的情况下，叶绿体外观发生了明显的变化。所获得的结果与其他已发表的描述矿物质缺乏对植物细胞超微结构影响的结果进行了讨论。
Observations were made by electron microscopy of the leaf cells of normal (full nutrient) tomato, spinach, and maize plants and of plants grown deficient in each of the known essential macro- and micronutrients except chlorine. In the case of spinach, observations were also made by phase contrast and fluorescence microscopy. A feature of this study was the large variation found in the shape, size, and appearance of chloroplast sections from both full-nutrient and mineral deficient plants. A representative range of photographs showing this variation is presented. Specific changes in chloroplast appearance were found in the cases of manganese deficiency and iron deficiency and distinctive changes were found in the 10 other deficiencies. The results obtained are discussed in relation to other published results describing the effects of mineral deficiencies on plant cell ultrastructure.
