| sporulation and diversity of arbuscular mycorrhizal fungi in brazil pine in the field and in the greenhouse. | the aim of this work was to assess the sporulation and diversity of arbuscular mycorrhizal fungi (amf) at different forest sites with araucaria angustifolia (bert.) o. ktze. (brazil pine). in addition, a greenhouse experiment was carried out to test the use of traditional trap plants (maize + peanut) or a. angustifolia to estimate the diversity of amf at each site. soil samples were taken in two state parks at southwestern brazil: campos do jordão (parque estadual de campos do jordão [pecj]) and ... | 2007 | 17342509 |
| current state and projection of the probable original vegetation of the são carlos region of são paulo state, brazil. | a map of the native vegetation remaining in são carlos county was built based on aerial images, satellite images, and field observations, and a projection of the probable original vegetation was made by checking it against soil and relief surveys. the existing vegetation is very fragmented and improverished, consisting predominantly of cerrados (savanna vegetation of various physiognomies), semideciduous and riparian forest, and regeneration areas. araucaria angustifolia (bertol.) kuntze, found ... | 2003 | 14758712 |
| phytochemical evidence for the plant origin of brazilian propolis from são paulo state. | propolis and plant secretions from three species, most frequently mentioned as botanical sources of the bee glue in brazil (baccharis dracunculifolia, araucaria angustifolia and eucalyptus citriodora) have been investigated using gc-ms. based on chemical evidence, b. dracunculifolia was shown to be the main propolis source in são paulo state. the antibacterial and antifungal activities of all four materials were also tested, the most active being propolis and baccharis leaf exudate. | 1999 | 10431391 |
