同时测定了完整、不育大麦（Hordeum vulgare L.）P状态差异很大。在玫瑰细胞（Rosa sp.）在不同的时间段里，P在所用的实验条件下，胞外磷酸酶活性大大超过磷酸盐内流，但两者之间存在非常显着的相关性。细胞外磷酸酶参与磷酸盐运输的可能性进行了讨论。
The rate of phosphate influx, and the activity of extracellular phosphatase, were measured simultaneously in root systems of intact, sterile barley plants (Hordeum vulgare L.) of widely differing P status. Similar measurements were made on suspension cultures of rose cells (Rosa sp.) starved of P for various periods. Under the experimental conditions used, extracellular phosphatase activity greatly exceeded phosphate influx but there was a very significant correlation between the two. The possibility of the extracellular phosphatase being involved in phosphate transport is discussed.
