by the principal component analysis. Multivariate analysis of the metabolite profile revealed that 11 metabolites increased significantly in relation to the response types, mostly at post-inoculation stages, more prevalently (8 metabolites) at two days after inoculation than other stages, and more related to SS (7 metabolites) than RR (3 metabolites) or SR (one metabolite). This suggests most of the disease-related metabolites may be rarely pre-existing but mostly induced by pathogen infection... -

upregulation of chitinase and β-1,3-glucanase, phenylalanine ammonia lyase (PAL) activity and cell wall lignification. 1H and 13C NMR spectral data of one purified phytoalexin compared closely with 4``-hydroxyanigorufone. Some of the P. musarum-induced defences that retained during ripening, restrict C. musae development at the ripe stage. This paper examines the potential of P. musarum-induced defences, in the control of anthracnose, the most destructive postharvest disease in banana. -

Particulate matter research is of great significance in solving atmospheric environment problems. The heterogeneous reaction of mixed gas on different mineral oxides and coal ash was studied based on a laboratory-built aerosol generating reactor. The product formed on particles was investigated by ion chromatography (IC). SO2 and NO2 could react on oxides to form secondary particles and the order of reactivity of mineral oxides under laboratory reaction conditions is: Al2O3>MgO>CaO>>SiO2, Fe2O3....
