Trait physiology and crop modelling as a framework to link phenotypic complexity to underlying genetic systems (2005, background): “The onset of leaf senescence can be delayed by increased soil-N uptake during grain filling, as observed under terminal drought stress by Borrell and Hammer (2000). Such increased N-uptake could be associated with either increased water uptake (i.”
Physiological traits and cereal germplasm for sustainable agricultural systems (2007, background): “Genetic differences in staygreen among sorghum lines have recently been shown to be associated with increased nitrogen uptake and with enhanced yields in dry environments ( Borrell and Hammer, 2000 ).”
Assessment of nutrient use in annual and perennial crops: A functional concept for analyzing nitrogen use efficiency (2011, background): “The major growth period is followed by a final period characterized by ceased growth and dominated by nutrient and carbohydrate relocation processes, which greatly affect the crop N dynamics (e.g. “stay-green”, Borrell and Hammer 2000).”
Breeding for increased nitrogen‐use efficiency: a review for wheat (T. aestivum L.) (2016, background): “…in the maintenance of green leaf area in sorghum, with ‘stay-green’ in sorghum hybrids linked to changes in the balance between N demand and supply during grain filling resulting in a slower rate of N translocation from the leaves to the grain (Borrell and Hammer 2000, Van Oosterom et al. 2010a,b).”
Stay-green expression in early generation sorghum [Sorghum bicolor (L.) Moench] QTL introgression lines (2010, background): “For example, Rajcan and Tollenaar (1999) found that the stay-green maize hybrid Pioneer 3902 accumulated 60% of total plant N after silking, compared to only 40% in the case of senescent hybrid Pride 5. Borrell and Hammer (2000) reported that stay-green sorghum hybrids had a higher percentage of t”
Developmental and physiological traits associated with high yield and stay-green phenotype in wheat (2008, unknown): “For example, in certain stay-green sorghum hybrids, changes in the balance between N demand and supply during grain ﬁlling compared with senescent genotypes are thought to result in a slower rate of N (BorrellandHammer2000).”
Dual-purpose cereals: Can the relative influences of management and environment on crop recovery and grain yield be dissected? (2011, unknown): “Studies of sorghum have shown that DM accumulation improves by maintaining IPAR during later stages of kernel filling (Borrell and Hammer 2000). Since grazing typically delays crop development, it is possible that defoliation will also affect the duration of growth and green area duration after anth”
Evaluation of stay-green sorghum germplasm lines at ICRISAT (2002, background): “Cluster 1 genotypes, which combined ing grain filling (Borrell and Hammer, 2000), which is nonsenescence with drought escape, through early flowering, were possibly associated with a higher transpiration efficiency superior to Cluster 2 genotypes, which were nonsenescent but late in the best…”
Functional dynamics of the nitrogen balance of sorghum. II. Grain filling period. (2010, background): “This has been observed inmany studies on sorghum (Khanna-Chopra and Sinha, 1988; Kamoshita et al., 1999; Borrell and Hammer, 2000).”
Drought resistance, water-use efficiency, and yield potential-are they compatible, dissonant, or mutually exclusive? (2005, background): “Nonsenescence is an important factor in sustaining a positive plant nitrogen balance such as in maize (Ma and Dwyer 1998) and sorghum (Borrell and Hammer 2000).”
Mechanisms of Nitrogen Use in Maize (2019, background): “Enhanced photosynthetic capacity can contribute to greater biomass and grain yield [74].”
