Nitrogen partitioning and remobilization in relation to leaf senescence, grain yield and grain nitrogen concentration in wheat cultivars ☆ (2014, methodology): “Samples were analyzed for soil mineral (NO3− and NH4+) as described by Gaju et al. (2011).”
Breeding for increased nitrogen‐use efficiency: a review for wheat (T. aestivum L.) (2016, background): “‘Stay-green’ phenotypes and broader genetic variation in senescence have been reported in hexaploid wheat (Silva et al. 2000, Verma et al. 2004, Joshi et al. 2007, Christopher et al. 2008, Chen et al. 2010, 2011, Bogard et al. 2011, Gaju et al. 2011, Derkx et al. 2012, Naruoka et al. 2012).”
The Physiological Basis of the Genetic Progress in Yield Potential of CIMMYT Spring Wheat Cultivars from 1966 to 2009 (2015, background): “Future work to enhance wheat yields should also seek to enhance stay-green, for example, by maximizing canopy N accumulation and slowing postanthesis N remobilization (Derkx et al., 2012; Gaju et al., 2011, 2014).”
Diverse concepts of breeding for nitrogen use efficiency. A review (2017, background): “Gaju et al. (2011) found that the timing of the onset of senescence explained 86% of the variation in NUtE under low N, but no significant correlation between onset of -0.4 -0.2 0.0 0.2 0.4 0.6 0.8 0.4 0.5 0.6 0.7 0.8 0.9 1.0 1.1 1.2 1.3 1.4 1.5 1.6 1.7 1.8 1.9 2.0 I II IVIII Dry matter yield (Low…”
