Abstract/Contents:"Five physiological indicators, i.e. the leaf relative water content, the leaf cell membrane permeability, the net accumulation of free proline in leaves, the relative leaf water potential and the relative root vigor were measured using four grass cultivars with different salt tolerance. These indicators were measured after the salt stress for 5, 10, 15, 20, 25 and 30 days in the NaCl stress treatments of 0.0, 0.2%, 0.4%, 0.6%, 0.8% and 1.0% (NaCl/soil dry weight or w/v) respectively. The results showed that these five physiological indicators are all suitable for salt evaluation. The cultivars with higher relative water content, lower cell membrane permeability, less accumulation of free proline, higher relative water potential in leaves and higher relative root vigor are more salt tolerant. The mean value of several measurements during one month of moderately high salt stress are more suitable for salt evaluation. The path analysis of these five physiological indicators to the salt tolerance reveals that the relative water potential and the net accumulation of free proline in leaves have the strongest direct effects on the salt tolerance, and they are the main indicators determining the tolerance. The mass free proline accumulation is a symptom of salt stress in grasses."
