Morphological variation of Aechmea distichantha (Bromeliaceae) in a Chaco forest: habitat and size-related effects.

摘要: Plants show different morphologies when growing in habitats, but they also vary their morphology with plant size. We examined differences sun- and shade-grown plants of the bromeliad Aechmea distichantha respect to relationships between size variables related architecture, biomass allocation tank water dynamics. selected vegetative from understorey forest edges a Chaco forest, encompassing whole range this bromeliad. Plant was positively correlated most architectural negatively variables. Understorey were taller had larger diameters, whereas sun more leaves, sheath area, mass fraction.
