Other claims from this paper (10)
- Association Seed germination rate and seedling survival rate were highest at 50% full sunlight.
- Association Root, stem, leaf and total seedling biomass were all highest at 50% full sunlight.
- Association Increasing light intensity promoted more biomass distributed to roots.
- Association Increasing light intensity promoted more overground biomass distributed to leaves.
- Association Increasing light intensity raised the Chla/Chlb and Car/Chl ratios.
- Association Below full sunlight, MDA, SOD and POD activities in seedling leaves and roots showed incremental trends with increasing light intensity.
- Association At full sunlight, MDA contents and SOD and POD activities of seedling leaves declined.
- Association Pro contents of seedling leaves and roots were lowest at 25% full sunlight.
- Recommendation About 50% full sunlight is the suited light intensity for germinating seeds and growing seedlings of T. longibracteata.
- Association Full sunlight is not suitable for seedling biomass accumulation.
