Fibre pits in wood of Xylopia emarginata Mart. (Annonaceae), Reserva Biológica e Estação Ecológica de Mogi-Guaçu, São Paulo State, Brazil
(Fibre pits in wood of Xylopia emarginata Mart. (Annonaceae), Reserva Biológica e Estação Ecológica de MogiGuaçu, São Paulo State, Brazil). The influence of environmental conditions such as flooding areas on the anatomical features of wood is little known. The aim of this study was to compare the fibre pits in the stems and in the roots of Xylopia emarginata growing in a swampy forest and in a ...
متن کاملViability of recently harvested and stored Xylopia aromatica (Lam.) Mart. (Annonaceae) seeds1
Xylopia aromatica is a native species from Brazil’s “Cerrado”, recommended for restoration ecology and also as a medicine. Its seeds have embryos with morphophysiological dormancy, making nursery propagation difficult. The objective of this study was to verify the efficiency of X-ray and tetrazolium tests for evaluating the viability of three seed lots, stored for different periods. All seeds w...
متن کاملLeaf development in Xylopia aromatica (Lam) Mart. (Annonaceae): implications for palatability to Stenoma scitiorella Walker 1864 (Lepidoptera: Elachistidae).
Variations in specific foliar mass and water content, nitrogen, soluble carbohydrates and tannins were studied during the growth and maturation processes of the Xylopia aromatica leaves, to determine the effects of such alterations on the herbivory of Stenoma scitiorella caterpillars. This work was carried out in the physiognomy of the typical cerrado of the Parque Estadual de Vassununga, Gleba...

متن کاملA new species of the lenticel fungal genus Claviradulomyces (Ostropales) from the Brazilian Atlantic forest tree Xylopia sericea (Annonaceae)
Claviradulomyces xylopiae sp. nov. is introduced for a fungus occurring in association with abnormal (enlarged, spongy) lenticels of Xylopia sericea (Annonaceae), a common tree of the Atlantic forest and Cerrado ecosystems in Brazil. This is the second species described in the genus and, although it is morphologically distinct from the type species, C. dabeicola from West Africa, it possesses t...
