Abstract excerpt
Silicon (Si) modulates plant responses to abiotic stress, but its role in legumes remains unclear. We investigated the effects of Si supply on drought responses in common bean genotypes contrasting in drought tolerance (BAT 477, tolerant; IAC Carioca 80 SH, susceptible), focusing on leaf gas exchange, carbon isotope discrimination (δ13C), leaf nitrogen (N), and C/N. Plants were grown under greenhouse upon...
