| Abstract: In this research, we studied the effect of water stress on dry weight, water content, total, α and β-amylases, soluble sugars, protein content and proline content in seedlings of Pisum sativum seeds. The water stress was generated using by PEG-4000 in several concentrations (0.1, 1, 5, 10, 20 and 30 %). Increase in PEG concentration decreased water content as compared with control, whereas dry weight increased with increasing the concentration of PEG. Total, α and β-amylases decreased progessively with increasing of water stress level, whereas high concentrations of PEG decreased soluble sugars as compared with control. The content of protein decreased with increasing of PEG concentrations, whereas proline content increased with increasing of PEG concentrations. | ||
