Grain Filling and Dry Matter Translocation Responses to Source–Sink Modifications under postnathesis water and nitrogen deficiency - DOI: 10.4025/actasciagron.v32i1.6273 Agronomy Madani, Ahad; Islamic Azad University; Rad, Amirhossein Shirani; Seed and Plant Improvement Institute; Pazoki, Alireza; Islamic Azad University; Nourmohammadi, Ghorban; Islamic Azad University; Zarghami, Reza; Agricultural Biotechnology Research Institute. Abstract: 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 its contribution to grain yield and Source limitation increased stem and spike reserves contribution to seed filling process. More amount of stem reserve mobilization in source restricted vs. control and sink restricted plants indicates that at rapid grain filling stage (14 days after anthesis to physiological maturity), stem dry matter decrease to provide assimilates for kernel after defoliation. In spike halved plants, drought stress significantly decreased grain yield indicates that when the...
