14. Powdery mildew damage to the production of BRS 189 cashew plants
ABSTRACT Powdery mildew, caused by the fungus Pseudoidium anacardii, is currently the most important cashew disease, affecting leaves, inflorescences, and fruits. However, there is a lack of detailed reports associating the effects of P. anacardii to cashew yield. Therefore, the objective of this study was to determine the damage caused by powdery mildew to

19. Floral resins of Philodendron adamantinum (Araceae): secretion, release and synchrony with pollinators
ABSTRACT Philodendron is the only genus of Araceae in which resin release occurs in the inflorescence. The resinous secretion adheres to the smooth body surface of the pollinating scarab beetles and allows attachment of pollen grains, making its transport possible. In order to understand the process of resin synthesis and release to the external environment,

20. Two new species of Drosophila (Diptera, Drosophilidae) associated with inflorescences of Goeppertia monophylla (Marantaceae) in the city of São Paulo, state of São Paulo, Brazil
Abstract Two new Brazilian species of Drosophila (subgenus Drosophila) are described and illustrated: Drosophila asymmetrica sp. nov. and Drosophila peixotoi sp. nov. Both species were collected, and emerged, from inflorescences of Goeppertia monophylla (Marantaceae) in the urban Forest Reserve of the Instituto de Biociências da Universidade de São Paulo a

23. Piper gaudichaudianum Kunth: Seasonal Characterization of the Essential Oil Chemical Composition of Leaves and Reproductive Organs
ABSTRACT This study describes a comparative analysis of the essential oil (EO) chemical composition of leaves and reproductive organs (inflorescences and fruits) of Piper gaudichaudianum during the seasons of a year in order to determine the best collection time and the most suitable plant organ to obtain this extractive. The chemical composition of EO obtai

24. Patterns of growth, development and herbivory of Palicourea rigida are affected more by sun/shade conditions than by Cerrado phytophysiognomy
ABSTRACT Plant development is influenced by several abiotic factors, which in turn influence morphological traits and life history. We investigated whether leaf area, herbivory, toughness, fluctuating asymmetry, structural complexity and the number of inflorescences of Palicourea rigida are influenced by sun/shade conditions or by Cerrado phytophysiognomy (t
