Chromium was not required for normal growth of romaine lettuce (Lactuca sativa L. subsp. longifolia), tomato (Lycopersicon esculentum Mill.), wheat (Triticum aestivum L.), or bean (Phaseolus vulgaris L.) in solution culture containing 3.8 x 10(-4) muM Cr. Plants grown on this purified nutrient solution contained an average of 22 ng Cr/g dry weight. Duckweed (Lemna sp.) grew and reproduced normally on a dilute nutrient solution containing 3.8 x 10(-5) muM Cr.
在含有 3.8 x 10(-4) μM Cr 的溶液培养中,铬不是长叶莴苣(Lactuca sativa L. subsp. longifolia)、番茄(Lycopersicon esculentum Mill.)、小麦(Triticum aestivum L.)或菜豆(Phaseolus vulgaris L.)正常生长所必需的。在这种纯化的营养液中生长的植物平均含有 22ng Cr/g 干重。浮萍(Lemna sp.)在含有 3.8 x 10(-5) μM Cr 的稀营养液中正常生长和繁殖。
