Oxygen partial pressures in the vacuolar sap of root cells have been measured using oxygen sensitive polarographic microelectrodes. A significant gradient in oxygen partial pressure was observed across intact sunflower roots growing in air saturated culture solution. The relevance of this finding to the mechanism of salt transfer across the root and in particular to the Crafts-Broyer theory is discussed.
使用氧敏感的极谱微电极测量了根细胞液泡中氧分压。在空气饱和培养液中生长的完整向日葵根中，观察到氧分压存在显著的梯度。本文讨论了这一发现与盐在根中转运的机制，特别是与 Crafts-Broyer 理论的相关性。
