Wheat (Triticum aestivum L.) grain filling and dry matter partitioning responses to source:sink modifications under postanthesis water and nitrogen deficiency = Enchimento de grãos de trigo (Triticum aestivum L.) e respostas da partição de matéria seca às modificações fonte:dreno sob deficiência de água e nitrogênio após a antese

Re-translocation of stem and spike reserves was investigated in source:sink restricted wheat subjected to water and nitrogen deficiency during seed filling. Either sink or source restriction significantly decreased the amount of current photosynthesis and itscontribution to grain yield. Furthermore,...
