| Περίληψη: | Background: Phosphorus (P) deficiency is a major factor limiting crop productivity in many soils worldwide. This study aimed to investigate the potential of seed priming with monopotassium phosphate (200 mmol L-1) to alleviate the adverse effects of P deficiency in Chenopodium quinoa Willd. Seedlings issued from unprimed and primed seeds were cultivated in plastic pots filled with inert sand under P deficient or P sufficient conditions. Results: In plants from unprimed seeds, P deficiency decreased shoot and root growth, leaf P and potassium ion (K+) content, leaf water content, gas-exchange performance, and photosynthetic pigment concentrations, while increasing lipid peroxidation and leaf acid phosphatase activity. Interestingly, monopotassium phosphate (KH Conclusion: KH (© 2026 Society of Chemical Industry.) |
