STUDIES ON THE RELATION BETWEEN RESISTANCE TO SPHACELOTHECA REILIANA (KIIHN) CLINT VAR.ZEAE PASS.AND 1,4-DIHYDROXY-7-METHOXY-2H-1,4-BENZOXAZIN-3(4H)-ONE IN CORN Duration and dosage effect of chemical defense in maize (Zea mays) mediated by exogenous ethephon Effects of DIMBOA stress on oxidation reduction system of the Asian corn borer, Ostrinia furnacalis (Guenée) (Lepidoptera: Crambidae) Systematically induced effects of Tetranychus cinnabarinus infestation on chemical defense in Zea mays inbred lines. Resistance to aphid determining and screening in wheat species (lines) or sources Changes of DIMBOA Contents in Resistant and Susceptible Near-Isolines of Maize during Infection by Exserohilum turcicum Change in concentration of secondary metabolites- DIMBOA and phenolic acids in leaves of Bt corn Responses of winter wheat seedling growth and allelochemical content to elevated CO2 and O3 concentrations.
