Abstract

Soil salinization is becoming increasingly severe and has emerged as a significant abiotic stress factor affecting crop yields. In order to investigate the role of Conyza canadensis’s allelopathic in alleviating salt-induced damage to crops and fostering salt-tolerant varieties, this study examined some indicators of maize seed germination during three levels of salt stress treatments (0, 150, 300 mmol/L) and three concentrations (0, 30, 60 g/L) of Conyza canadensis water extract (CCE). The results demonstrate that the application of CCE enhances the germination rate and germination energy of maize seeds under salt stress conditions. In addition, CCE significantly promotes main root length and stem height development in maize with salt-free stress. Moreover, CCE supplementation increased the chlorophyll content of maize exposed to various salt concentrations. Evaluation showed that low concentrations of CCE facilitated seed germination and improved salt tolerance at all levels of salinity, while high concentrations of CCE enhanced seed germination and salt tolerance at high salinity. Therefore, Conyza canadensis showed good ecological benefits in improving the salt-tolerant ability of maize during germination.
