Salinity stress is known to have a detrimental effect on mint plants. The aim of the present work was to investigate the possible effects of salinity stress on , and . Plants were exposed to salinity stress using different concentrations of NaCl (0, 50, 100, 150 mM). Under salinity stress, plant growth, oil yield, content and composition, as well as physiological parameters were adversely affected. Among the studied species, experienced the maximum loss in terms of oil percentage. Physiological characteristics and oil composition were significantly affected with intensification of salt stress. For instance, in , with increasing salinity stress, piperitone oxide was decreased from 78.4% in control to 38.0% in 150 mM NaCl, whereas menthol was increased from 1.0 to 37.1%. Moreover, in , menthone, isomenthone and limonene were all increased in low stress and then were decreased in high stress conditions. In , the major compound; menthol was not affected but the content of menthone increased. It could be concluded that the salinity stress is detrimental but might be useful and may be recommended as an appropriate approach in improving the oil quality or to producing specific compounds under mild or moderate stress.
已知盐胁迫对薄荷植物有不利影响。本研究的目的是调查盐胁迫对[具体内容缺失]、[具体内容缺失]和[具体内容缺失]的可能影响。使用不同浓度的NaCl（0、50、100、150 mM）对植物施加盐胁迫。在盐胁迫下，植物生长、油产量、含量和组成以及生理参数均受到不利影响。在所研究的物种中，[具体物种缺失]在含油率方面损失最大。随着盐胁迫加剧，生理特性和油组成受到显著影响。例如，在[具体物种缺失]中，随着盐胁迫增加，氧化胡椒酮从对照中的78.4%降至150 mM NaCl处理下的38.0%，而薄荷醇则从1.0%增加到37.1%。此外，在[具体物种缺失]中，薄荷酮、异薄荷酮和柠檬烯在低胁迫下均增加，然后在高胁迫条件下减少。在[具体物种缺失]中，主要成分薄荷醇未受影响，但薄荷酮含量增加。可以得出结论，盐胁迫是有害的，但可能是有用的，并且可能被推荐为在轻度或中度胁迫下改善油质量或生产特定化合物的合适方法。
