Short-term Waterlogging-induced Changes in Phosphatase Activities in Shoots and Roots of Sorghum Seedlings: Role of Phosphatases during Waterlogging in Relation to Phosphorus

Short-term waterlogging stress-induced changes in phosphatase (P-ase) activities in relationship with phosphorus were studied in sorghum (Sorghum bicolor). Waterlogging was imposed by watering 3-day-old grown seedlings with water. The shoots and roots were harvested and P-ase activities were estimated. Significant waterlogging stress-induced increase in shoot and root P-ase activities coupled with low phosphorus level was observed at various time points. The shoot and root P-ase activities confer adaptation to plants under waterlogging stress.
