Physiological effects on grain yield formation of amaranth
Abstract
Grain amarant is a warm-season C4 crop with advantageous drought tolerance and grain composition. The heterogeneous ripening and the comparatively low yield are challenges that need attention. The project will study the yield determining factors, especially the source-sink relations during yield formation. The investigations cover grain yield and grain weight, biomass yield, harvest index and grain composition. Relations are sought between photosynthetic activity, seed set and development and final yield.
