Roots have layered secondary phloem; short sieve tubes with simple, transverse or more or less inclined sieve plates; fibres in tangential bands; astrosclereids; wide rays, and a poorly developed periderm. Stems ha...

No. of bitstreams: 0 Previous issue date: 2006-01-01; Cambial activity and periodicity of secondary xylem formation in Cedrela fissilis, a semi-ring-porous species, were studied. Wood samples were collected periodically from 1996 to 2000. The phenology was related to climate data of the region. The cambium has one active and one dormant period per year. Th...

(Styracaceae) has a wide distribution in Brazil, occurring in diverse ecosystems. To get a better insight into the ecological adaptations of wood structure, we studied two species, S. camporum and S.ferrugineus from the cerrado, and three species, S. latifolium, S. martii and S. lepr...
