Other claims from this paper (6)
- Observation Photochemical parameters such as ΦII and qL varied across switchgrass genotypes.
- Observation Photochemical parameters such as ΦII and qL were not strong predictors of switchgrass shoot biomass.
- Association Respiratory efficiency, particularly low root respiration relative to shoot mass, was more strongly associated with higher switchgrass yield.
- Mechanism Switchgrass genotypes DVR3 and FLT1 achieved greater biomass through reduced respiratory costs and efficient nutrient use, despite moderate photosynthetic performance.
- Observation Ecotypic distinctions in switchgrass were observed along PC1.
- Observation Some upland switchgrass genotypes displayed trait profiles overlapping with lowland genotypes.
