Factores ambientales que afectan el contenido de fumonisina en granos de maíz

Regression logistic techniques were used to study the environmental variables associated with fumonisin content in maize grain. The dependent variable consisted of 29 values of fumonisins B1 and B2 (FB1 and FB2) from samples of susceptible hybrid sowed in several sites of the Pampas region from 2006/07 to 2008/09. Meteorological variables were recorded in relation to the silking stage. The Np2 variable (number of periods of two days with simultaneous recording of rainfall and relative humidity > or = 81 % (day 1) and relative humidity > 70 % at the second day) was the most strongly correlate...
