Crop growth can be estimated by the amount of radiation intercepted by canopy and the efficiency of its conversion to dry matter. Diurnal and seasonal changes of photosynthetically active radiation (PAR), both intercepted and reflected by the canopy, were measured throughout a growing season for the spring wheat cultivars Haruyutaka and Selpek. The changes were correlated with total surface area including the leaves, culms, ears and senescent parts. The daily mean values of diurnal changes in… CONTINUE READING
