Title

Other claims from this paper (8)
- Intervention effect Rhizome respiration at 25°C was 5.3 times that at 5°C.
- Intervention effect Storage at 25°C depleted rhizome starch by 30%.
- Intervention effect Reserve depleted switchgrass had 60% larger leaf area than controls.
- Intervention effect Reserve depleted switchgrass produced about 40% more aboveground biomass than controls.
- Observation Reserve depleted switchgrass restored rhizome starch to pre storage levels.
- Mechanism Switchgrass increased plant photosynthesis by increasing photosynthetic leaf area.
- Observation Switchgrass readjusted the timing and activity of sink organs.
- Recommendation The authors suggest breeding to extend the aboveground growing season should not compromise perennial grass persistence.
