Saline–alkali (SA) stress is an abiotic that exists widely in the natural environment, seriously affecting growth and development of crops. Tiger nut (Cyperus esculentus L.), a perennial herb Cyperus Cyperaceae, considered pioneer crop for growing improving SA land due to its excellent adaptability tolerance. This study first evaluate tolerance tiger alleviative effects nanomaterials (nano-selenium multi-walled carbon nanotubes) Arbuscular mycorrhizas (AMs) on stress. The results showed seedling fresh weight was most suitable parameter describe dose–response effect plant with increased concentration. Based log-logistic curve, GR50 values NaCl NaHCO3 (the concentrations causing 50% reduction weight) were determined be 163 mmol L−1 63 L−1, respectively. Under these stresses, exogenous application MWCNTs at 100 mg or Nano-Se 10 alleviated. Field evaluation further MWCNTs, Nano-Se, AMs could effectively alleviate nut. Compared untreated control, substances significantly improved photosynthesis-related parameter, antioxidant enzyme activity, height (height: 66.0–69.9 cm), tuber yield (yield: 23.4–27.4 g plant−1), oil quality under this indicate AMs, can maintain seed yield, providing possibility using nanoparticles improve agricultural practice.

Aluminum (Al) may be beneficial to crops, but in excess becomes detrimental the germination and initial development of seedlings. The main determining indicators are type crop exposure duration. aim this study was examine influence Al UV-C light on growth white oats. Seeds were sown germitest paper a solution 100, 200, 300, 400, or 500 mg/L aluminum chloride kept chamber at 20°C for 12-hr photoperiod. Germination seedling parameters determined after 5 10 days. seeds also exposed two doses (0.85 3.42 kJ m
