| description | With the expansion of saline-alkaline tolerant rice in China, the effects of salinity stress (NaCl) on quinclorac-resistant <i>Echinochloa crus</i><i>-galli</i> (L.) Beauv (<i>E. crus-galli</i>) is unclear. In this study, the growth chamber experiment was conducted to test the germination and growth physiology of seven populations of <i>E. crus-galli</i> with quinclorac-different resistance levels which were collected from Hunan province. The results showed that a significant decrease of the germination rate and fresh weight of the plants, as well as the length of the roots and young shoots appeared, along with the increased resistance while treated with NaCl. However, no significant differences were detected between quinclorac-resistant and -susceptible <i>E. crus-galli</i> populations while without NaCl treatment. A further study with spectrophotometer showed that the salinity treatment resulted in the increase of the GST activity in all <i>E. crus-galli</i> populations, which are more obvious in those resistant biotypes, and transcriptomics revealed that salt stress reduces the adaptability of quinclorac-resistant <i>E. crus-galli</i> by reducing the biosynthesis, activities of antioxidant enzymes and metabolic enzyme. This study demonstrated that salinity stress (NaCl) may reduce the adaptability of quinclorac-resistant <i>E. crus-galli</i>. |
