Other claims from this paper (11)
- Observation Primary needles had high net photosynthetic rate, maximum photochemical efficiency, and water use efficiency.
- Observation Primary needles had higher non-photochemical quenching, interpreted as a response to sudden light increases.
- Observation Secondary needles had lower transpiration rate, stomatal limitation and light saturation point.
- Association Secondary needles increased leaf fructose and glucose compared with primary needles.
- Association Secondary needles increased leaf biomass proportion from 47.06% to 54.30%.
- Association Secondary needles enhanced the proportion of starch stored in roots.
- Observation Non-structural carbohydrate accumulation increased significantly in seedling leaves and roots.
- Association Carotenoids, chlorophyll a and total chlorophyll directly increased primary needle seedling biomass.
- Mechanism Photosynthetic pigments indirectly promoted biomass through increased stem soluble sugar synthesis.
- Association Net photosynthetic rate was the main physiological factor determining primary needle seedling biomass.
- Association Water use efficiency, stomatal limitation and non-photochemical quenching directly reduced primary needle seedling biomass.
