Silicon mitigates nutritional stress in quinoa (Chenopodium quinoa Willd.)

Abstract Nutritional deficiency is common in several regions of quinoa cultivation. Silicon (Si) can attenuate the stress caused by nutritional deficiency, but studies on the effects of Si supply on quinoa plants are still scarce. Given this scenario, our objective was to evaluate the symptoms in te...
