25. Phenology and agronomic components of first and second-cycle strawberry
RESUMO Em busca de maior retorno econômico após o transplantio das mudas, muitos produtores de morango têm feito o cultivo por dois ciclos consecutivos. No entanto, há necessidade de estimar o desenvolvimento fenológico e avaliar o potencial agronômico do morangueiro nesse sistema. O objetivo deste trabalho foi comparar a necessidade térmica, a taxa d

26. Influence of Phenology and Post-Harvest Processing of Vegetal Material on the Allelopathy of Annoni Grass (Eragrostis plana) Extracts
RESUMO: O estádio fenológico da planta, a quantidade e o processamento do material vegetal são fatores que podem interferir na atividade alelopática dos extratos. Este trabalho teve como objetivo testar o efeito alelopático de extratos aquosos de folhas de capim-annoni (Eragrostis plana), invasora de pastagens naturais. Doze extratos foram elaborados, r

27. Pollination and quality of seeds and plantlets of Eugenia uniflora L.
RESUMO Este trabalho avaliou o efeito da polinização na qualidade de sementes e mudas de Eugenia uniflora L., assim como na capacidade de regeneração das sementes. Doze indivíduos tiveram sua fenologia e seus visitantes florais acompanhados. Flores recém-abertas foram submetidas aos tratamentos de autopolinização (AP), polinização cruzada (PC) e co

28. Relationship between the normalized difference vegetation index and leaf area in vineyards
ABSTRACT In vineyards, the monitoring of leaf area is used to guide management practices in order to produce grapes with quality and enological potential. Remote sensing has been used to estimate leaf area by means of vegetation indices. This work aimed at determining the temporal evolution of the Normalized Difference Vegetation Index (NDVI) while associati

29. Leaf phenology, growth and photosynthesis in Pseudobombax munguba (Malvaceae)
RESUMO A munguba (Pseudobombax munguba) é uma árvore encontrada com frequência em florestas de baixios da Amazônia e há escassez de informação sobre a sua ecofisiologia. O objetivo deste trabalho foi determinar as taxas fotossintéticas e o crescimento de arvoretas de munguba e descrever a fenologia foliar de uma árvore adulta. Em arvoretas em casa d

30. Production of Fodder in a Treeless System and in Silvopastoral System in Central Argentina
ABSTRACT This paper aims to identify the spatial and temporal distribution of net aerial primary production (NAPP) of oats and sorghum in silvopastoral systems (SPS) and in a treeless situation (TLS), in Southern Cordoba, Argentina. The silvopastoral systems are composed of three woody cultures (Pinus elliottii, Eucalyptus viminalis and Quercus robur), and

31. Reproductive morphology and phenological aspects of one morphological variant of Hypnea pseudomusciformis (Gigartinales, Rhodophyta)
ABSTRACT Hypnea pseudomusciformis was recently described from South America, and has three morphological variants: “musciformis”, “nigrescens”, and “valentiae”. Information on the biology of these variants may help to explain this species’ wide morphological variation despite the absence of genetic divergence among variants. More morphological

32. Reestablishment, new records, and a key for the species of Aspidosperma (Apocynaceae) from the Brazilian Amazon
ABSTRACT As a result of systematic study of the Neotropical genus Aspidosperma (Apocynaceae), we reestablish the species A. centrale and A. duckei, and report A. steinbachii and A. tambopatense as new records for Brazil. We provide taxonomic descriptions of these species along with plates, distribution maps, and information on their conservation status, habi

33. Boll weevil within season and off-season activity monitored using a pheromone-and-glue reusable tube trap
ABSTRACT: The boll weevil colonizes cotton fields as early as cotton squaring, causing significant losses due to feeding and protected development inside fruiting structures throughout crop phenology. Successful control depends on control of adults and their accurate detection when they colonize the crops. The commercial trap and boll weevil attract-and-cont

34. Pollination biology of melittophilous legume tree species in the Atlantic Forest in Southeast Brazil
ABSTRACT This study describes the floral phenology and morphology, reproductive biology and pollinators for eight legume tree species, Schizolobium parahyba, Senna macranthera, and Senna multijuga (Caesalpinioideae), as well as Andira fraxinifolia, Lonchocarpus cultratus, Pterocarpus violaceus, Swartzia oblata, and S. simplex (Papilionoideae), in the Atlanti

35. Capitulum and floret phenology in Baccharis aliena (Asteraceae, Astereae)
Abstract Inflorescence and floral phenological studies are a source of valuable knowledge to interpret reproductive mechanisms and phylogenetic hypothesis in plants. We analyzed the morphology and functionality floret stages that are present in pistillate homogamous and functionally staminate heterogamous capitula of the dioecious species Baccharis aliena. P

36. Phenology of Promestosoma boggianii (Diplopoda: Polydesmida: Paradoxosomatidae) in a Neotropical floodplain
ABSTRACT Studies that address biodiversity and its supporting mechanisms in different ecosystems are fundamental to understanding the relationships between species and the prevailing environmental conditions within each habitat type. This study presents information on the phenology of Promestosoma boggianii (Silvestri, 1898) and its association with seasonal
