Varietal Difference in Morphology and Photosynthetically Active Radiation Distribution in Spring Wheat Canopy
Canopy structure Crop ideotype PAR penetration Sowing time Spring wheat variety
font style='font-size:12px;'>
2009/8/4
It has been generally believed that the crop ideotype canopy has an erect small leaves to allow the photosynthetically active radiation (PAR) to penetrate deeply. In wheat, this might be not always ap...
Seasonal Changes in Distribution of Intercepted Photosynthetically Active Radiation for Layer and Dry Matter Production in Spring Wheat Canopy
Efficiency of dry matter accumulation Crop growth rate Photosynthetically active radiation Slope of flag leaf Spring wheat
