Autumn coloring, photosynthetic performance and leaf development of deciduous broad-leaved trees in relation to forest succession.
Autumn coloring of deciduous broad-leaved trees in northern Japan was found to develop either from the inner part of the crown outward (inner-type), or from the outer part of the crown inward (outer-type). Inner-type trees had early-successional characteristics, whereas outer-type trees had late-successional characteristics. Although alders (Alnus hirsuta (Spach) Rupr. and A. japonica (Thunb.) ...
متن کاملChanges in sapwood permeability and anatomy with tree age and height in the broad-leaved evergreen species Eucalyptus regnans.
Increases in plant size and structural complexity with increasing age have important implications for water flow through trees. Water supply to the crown is influenced by both the cross-sectional area and the permeability of sapwood. It has been hypothesized that hydraulic conductivity within sapwood increases with age. We investigated changes in sapwood permeability (k) and anatomy with tree a...
متن کاملLaser point-quadrat sampling for estimating foliage-height profiles in broad-leaved forests
A technique for estimating the vertical distribution of foliage area in broad-leaved forests was developed. The technique is similar to optical point-quadrat sampling, where estimates are based on heights to the lowest leaves above numerous sample locations beneath a canopy. In optical point-quadrat sampling, heights to lowest leaves are measured with a telephoto lens. Here, heights were measur...
متن کاملGeographical and climatic gradients of evergreen versus deciduous broad‐leaved tree species in subtropical China: Implications for the definition of the mixed forest
Understanding climatic influences on the proportion of evergreen versus deciduous broad-leaved tree species in forests is of crucial importance when predicting the impact of climate change on broad-leaved forests. Here, we quantified the geographical distribution of evergreen versus deciduous broad-leaved tree species in subtropical China. The Relative Importance Value index (RIV) was used to e...
