Strategic crossing of biomass and harvest index—source and sink—achieves genetic gains in wheat (2017, methodology): “…WYCYT and SATYN nurseries at the breeding site The selected progeny included in the WYCYT and SATYN nurseries were evaluated in replicated trials for yield and yield components using standard procedures as described previously for yield potential and heat stress environments (Reynolds et al. 2007).”
Physiological, Biochemical, and Molecular Mechanisms of Heat Stress Tolerance in Plants (2013, background): “Loss of productivity in heat stress is chiefly related to decreased assimilatory capacity [89] which is due to reduced photosynthesis by altered membrane stability [22] and enhanced maintenance respiration costs [90], reduction in radiation use efficiency (RUE, biomass production per unit of light i”
The yield correlations of selectable physiological traits in a population of advanced spring wheat lines grown in warm and drought environments (2012, background): “Mostly, these traits have been defined for drought and heat adaptation (Reynolds et al., 2007) and would explain their greater contributions to predict yield under low yielding environments where these stresses are experienced, as shown in the present study.”
Partitioning of assimilates to deeper roots is associated with cooler canopies and increased yield under drought in wheat (2010, background): “Indeed, it could be argued that the accumulation of WSC may be at the expense of investment in other adaptive strategiessuchasdeeperrootgrowth.Thisissupportedbythefact that WSC are being accumulated around anthesis, in the same time frame as differential root depth profiles are established among gen”
