Abstract:

The total of thirty-seven mid-late maturity maize varieties from regional trials in Shanxi province were used as experimental materials. Corn moisture determination meter PM-8188-A was used to measure the moisture in kernel of maize at four different temperatures and the measured values were compared with those by the traditional standard oven drying method. Using regression analysis, the corresponding real water mathematical equations for the maize kernels were established. This mathematical model would minimized the measuring errors caused by the environmental temperature in the process of capacitive quick water-content in kernel of maize in the field. It has certain application value for the breeder to select maize varieties with low moisture content at harvest time. The results showed that the measured value of the capacitor express method tended to increase with the increase of temperature within the range of 10℃ to 25℃, and the minimum measured error value was at 20℃.

Key words: Maize, Grain moisture content, Different temperatures, Error
