Other claims from this paper (18)
- Intervention effect Pharus latifolius increased ramet production and sexual reproduction in the sun treatment.
- Intervention effect Streptochaeta spicata increased ramet production and sexual reproduction in the sun treatment.
- Intervention effect Only Pharus latifolius developed greater maximum photosynthetic capacity under high irradiance.
- Intervention effect Streptochaeta sodiroana showed high mortality when grown in the sun.
- Intervention effect Streptochaeta sodiroana developed considerable photosynthetic efficiency when grown in shade.
- Observation No acclimation in the isocline parameters of the understory herbaceous bamboo was observed during drying.
- Observation Species differences in drought resistance corresponded to differences in osmotic potentials at saturation.
- Association Drought tolerance correlates with the regional distribution of the understory herbaceous bamboo species in wet and dry forest.
- Observation Stomatal conductance decreased as leaf water potentials declined.
- Observation Pharus latifolius showed marked stomatal closure after noon while leaf water potentials remained high.
- Observation Streptochaeta spicata maintained gas exchange throughout the day.
- Intervention effect Pharus latifolius allocated a higher percentage of ramet biomass to fruit production under high light and nutrient availability.
- Intervention effect Pharus latifolius produced larger leaves in gaps.
- Association Streptochaeta spicata fruit number and total biomass increased with light and nutrient availability.
- Intervention effect Streptochaeta spicata did not vary leaf size between gaps and shade.
- Observation Streptochaeta sodiroana was unable to use high levels of nutrients or light for growth and reproduction.
- Mechanism A large increase in photosynthetic surface area and maximum photosynthetic capacity allows Pharus latifolius to grow and reproduce in gaps.
- Mechanism Relatively continuous diurnal gas exchange permits Streptochaeta spicata to grow and reproduce in gaps.
