ABSTRACT	The effect of water stress, sorbitol and NaCl on acid phosphatase (APase) activity in detached rice leaves was investigated. APase activity was increased in detached rice leaves treated with methyl jasmonate (MJ), water stress, sorbitol, and NaCl. The induction of APase activity under water, osmotic and salt stresses, and MJ was not accompanied by a decrease in phosphorus level. These results suggest that the induction of APase under stress conditions and MJ may have a cause other than phosphorus deficiency. Evidence is presented to show that stress-induced APase activity is due to de novo APase synthesis and is unlikely to be mediated through MJ.
