Yield Predictive Worth of Pre-Flowering and Post-Flowering Indicators of Nitrogen Economy in High Yielding Winter Wheat

نویسندگان

چکیده

Indicators of nitrogen economy in winter wheat during vegetative development are a reliable tool for yield prognosis. This hypothesis was verified field experiment, carried out the 2013/2014, 2014/2015, and 2015/2016 seasons. The two-factor split-plot design, included following systems protection (CFP): (i) N + micronutrients, (ii) fungicides, (iii) micronutrients fungicides; rates: 0, 40, 80, 120, 160, 200, 240 kg ha−1. content accumulation at beginning stem elongation heading were used grain density prediction. In grain-filling phase, acted as buffer, stabilizing high level. condition such action equilibrium with ear flowering. depletion from leaves period significantly depended on density. post-flowering uptake by affected density, which reserves stem. Yield forecast based pre-flowering indices cereals affects both agronomic decisions aimed correcting nutritional status plants, farm economics.

Flowering time control in European winter wheat

Flowering time is an important trait in wheat breeding as it affects adaptation and yield potential. The aim of this study was to investigate the genetic architecture of flowering time in European winter bread wheat cultivars. To this end a population of 410 winter wheat varieties was evaluated in multi-location field trials and genotyped by a genotyping-by-sequencing approach and candidate gen...
