Growth and membrane stability of sweet corn (Zea mays L.) genotypes were evaluated to recognize the mitigative role of potassium against water deficit conditions. Water deficit conditions were created by withholding irrigation at different sampling stages. Water deficit stress negatively affected the growth attributes and cell membrane stability. Application of potassium increased the adaptation to water deficit stress by increasing membrane stability index and decreasing lipid peroxidation. Results procured from this study suggested that application of potassium could increase tolerance to water stress.
Key words : Growth, lipid peroxidation, membrane stability index, potassium, water deficit
