13. Fenologia e chuva de sementes em Floresta Estacional Semidecidual no município de Viçosa, Minas Gerais, Brasil. / Phenology and seed rain in Semidecidual Seasonal Forest in Viçosa, Minas Gerais, Brazil
The present study was divided in two chapters. On the first it was aimed to study the phenology of 20 arboreal species and to answer the following questions: (1) Which is the seasonality degree in the production of flowers, fruits, falling and leaf shooting? (2) Are there any flowering and fructification synchrony intra and interespecific? (3) What is the in

14. Fenodinamcia de lianas e forofitos em um fragmento de cerrado em Itirapina (SP) / Liana and tree phenodynamic in a cerrado fragment from Itirapina (SP), Brazil
Different life-forms with different resources allocation strategies can show different phenologies. Biotic and abiotic interactions and anthropogenic disturbance may additionally influence the phenology. The aims of this study were (a) to test the phenology between trees with and without lianas at the edge and in the interior of a dense cerrado fragment in I

16. Evapotranspiration of passionfruit and crop coefficient determined by energy balance and lysimeter hydraulic weighing. / Evapotranspiração e coeficiente de cultivo de maracujazeiros determinados pelo método do balanço de radiação e lisimetria de pesagem hidráulica.
This work was carried out at the experimental irrigation farm of the Engineering Department - College of Agriculture Luiz de Queiroz - ESALQ/USP in Piracicaba, São Paulo, State. The 83-day-old passiflora seedlings (Passiflora edulis Sims f. flavicarpa Deg cv. IAC 275) were transplanted to experimental units with rows planted based on North- South and East-W

18. Fenóis totais no cafeeiro em razão das fases de frutificação e do clima. / Total phenols in the coffee tree due to the fructification phases and the climate.
The vegetables show a natural defense against external factors, biotic and abiotic, by the synthesis of the phenolic compounds in the secondary metabolism, which varies with the maturity state and with the climate. The increase of phenolic compounds in the plants is directly related to the resistance to the infection thought pathogens and insect infestation.

19. Evapotranspiração e coeficiente de cultura em dois ciclos de produção do maracujazeiro amarelo. / Evapotranspiration and crop coefficient in two cycles of production of yellow passion fruit.
This work had as objective to determine the crop evapotranspiration (ETc) and the crop coefficient (Kc) of yellow passion fruit (Passiflora edulis Sims f. flavicarpa Deg), during 637 days after the transplant (DAT) of the seedling. The experiment was carried out in the experimental field of Fazenda Areão which belongs to ESALQ/USP, in Piracicaba, São Paulo

20. Classificação e monitoramento fenológico foliar da cobertura vegetal na região da floresta Nacional do Tapajós - Pará, utilizando dados multitemporais do sensor "thematic mapper" (TM) do Landsat / Phenology foliar classification and monitoring the vegetation cover in the Tapajós National Forest region Pará State, utilization multitemporal data from Landsat Thematic Mapper (TM) sensor
A importância relativa da acurácia no mapeamento da cobertura florestal se dá na necessidade da obtenção de melhoria na elaboração de planos de manejo dos recursos naturais e na determinação de áreas prioritárias para conservação, assim como na análise da paisagem. Outro aspecto que tem despertado cada vez mais interesse na comunidade científi

21. Fenologia e anatomia dos órgãos reprodutivos de Catasetum fimbriatum Lindley cultivados sob diferentes intensidades luminosas. / Fenology and anatomy of the reproductive organs of Catasetum fimbriatum Lindley cultivated under different luminous intensities.
As attempt of elucidating the environmental factors that they control the plasticity floral fenotipic of Catasetum fimbriatum Lindley, fenological, vegetative and anatomical studies of the species began, through of the accompaniment of 45 individuals. Thirty of these individuals were collected and put in the vases later. The other ones 15 already existed nat
