Comparison of leaf area index dynamics and radiation use efficiency of C3 crops in the Czech Republic
Original language description
Leaf area index (LAI) and radiation use efficiency (RUE) are key parameters for plant growth and productivity. Because of irregularities in weather conditions, accurate estimation of crop production requires understanding relationships between weather, LAI, RUE, and final production. It is thus important to study how the LAI dynamics, leaf area duration (LAD), and RUE are related to aboveground biomass production for different crops. In our study, we compared aboveground dry mass production, LAI dynamics, RUE, and LAD in three C3 crops (spring barley [SB], winter wheat [WW], and oilseed rape [OSR]) in the Czech Republic. LAI was measured on the basis of transmitted photosynthetically active radiation, LAD was calculated by counting the number of days in the growing season, RUE was measured using Beer's law, and the aboveground dry mass was estimated at the time of harvest. Results of our study showed high biomass production and RUE in SB while there was highest maximum LAI (LAImax) and LAD in OSR. We concluded that LAI dynamics or LAImax do not fully reflect the crop production and that RUE may be considered as a better indicator for aboveground dry mass production.
