Abstract

The effects of pH on the growth and the K+ (86Rb) uptake and K+ content of excised rice (Oryza sativa L. cv. Dunghan Shali) and wheat (Triticum aestivum L. cv. GK Szeged) roots were investigated. Rice roots responded to H+ stress with an increased K+(86Rb) influx and a decreased K+ content, suggesting an increased exchange between the cytoplasmic K+ pool and the external medium. Under the same experimental conditions wheat did not show any anomalous K+(86Rb) influx. Growth of both rice and wheat was relatively insensitive to pH between 4 to 10.
