Peas grown in media with elevated plant-available silicon levels have higher activities of chitinase and β-1,3-glucanase, are less susceptible to a fungal leaf spot pathogen and accumulate more foliar silicon

Abstract

Pea seedlings grown for 5 weeks in a growing medium amended with potassium silicate fertiliser had significantly greater activities of the enzymes chitinase and β-1,3-glucanase in leaf extracts compared with those grown in coir-based control mix, prior to challenge by a foliar pathogen. Additionally, fewer lesions developed on pea leaves inoculated with the… (More)
