Mikroklima porostu řepky a pšenice
 Krédl, Zdeněk
The purpose was clarification of vertical stratification of temperature and humidity in winter rape and winter wheat canopy and their comparison with the data from standard station. Air temperature and relative humidity was monitored in wheat and rape canopy in Žabčice during the main growth season in 2010 and 2011 years. Automatic sensors were positioned at three levels (on the ground, at the effective height and at 2 meters above the ground). According to crop developmental stage period was divided to three (four) parts. Air temperature and relative humidity in vertical profile of canopy differed significantly in dependence on year, wheat or rape developmental stage and time of day. The differences in vertical stratification of air temperature and relative humidity were pronounced especially during the light part of the day. In this time the temperature in ground part of canopy was significantly lower and the relative humidity was significantly higher. Air temperature measured in wheat or rape canopy was compared with data from standard meteorological stations, also. The results can be used in precision of prediction methods of some harmful agent's occurrence.
