25. Transformação genética de maracujazeiro (Passiflora edulis f. flavicarpa) para resistência ao vírus do endurecimento dos frutos / Passionfruit genetic transformation (Passiflora edulis f. flavicarpa) for resistance to woodiness virus
The main purpose of this work was to study an alternative way to control the Passionfruit woodiness virus - PWV through the production of transgenic plants which contained the Passionfruit woodness virus coat protein gene. The binary vector was built by using pCambia 2300 and pCambia 2301 plasmids, which contain the selection gene nptII. The pCambia 2301 pla

26. Linkage maps and QTL mapping in the yellow passion-fruit (Passiflora edulis Sims f. flavicarpa Deg.) / Mapas de ligação e mapeamento de QTL ("Quantitative Trait Loci") em maracujá-amarelo (Passiflora edulis Sims f. flavicarpa Deg.)
Although the yellow passion-fruit plays an important commercial role in Brazil, breeding and genetics studies are insipient. The present study was conducted aiming the construction of linkage maps and mapping of QTL for traits related to yield and fruit quality. It was used a population, composed of 160 individuals, derived from a cross from two plants of th

27. 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

28. Estudos anatomicos e ultra-estruturais da organogenese in vitro de Passiflora edulis Sims f. flavicarpa Deg / Anatomy and structural studies of in vitro organogenesis of Passiflora edulis Sims f. flavicarpa Deg
Meristemoids are responsible for the in vitro organogenesis expression. They may be formed from the explant (direct organogenesis) or from callus (indirect organogenesis). Once in vitro organogenesis is a prerequisite for developing micropropagation strategies and genetic transformation in plants, the ultrastructural analysis of the cells involved in such re

29. Análise filogenética de potyvírus causando endurecimento dos frutos do maracujazeiro no Nordeste do Brasil
Amostras foliares de plantas de maracujá-amarelo (Passiflora edulis f. flavicarpa) com sintomas típicos de endurecimento dos frutos foram coletadas nos estados de Pernambuco, Paraíba e Sergipe. A infecção viral foi comprovada por meio de teste sorológico e gama de hospedeiros. Os seis isolados virais obtidos foram capazes de infetar várias espécies t

30. Use of repellents for honeybees (Apis mellifera L.) in vitro in the yellow passion-fruit (Passiflora edulis Deg) crop and in confined beef cattle feeders
The presence of Apis mellifera in places such as candy and soft drink factories, restaurants, and ice-cream shops has been a concern to many people. In the yellow passion-fruit crop, Apis mellifera is able to collect all anther pollen but has no active role in pollination. Honeybees also visit animal feeders with chopped sugar cane, preventing the cattle fro

31. Estudos anatômicos e fisiológicos da organogênese in vitro em Passiflora cincinnata MAST. / Anatomical and physiological studies of organogenesis in vitro of Passiflora cincinnata MAST.
O avanço da cultura do maracujazeiro no país impulsionado pela agroindústria de suco e a crescente demanda de fruta fresca, acarretou o surgimento de problemas, principalmente de ordem fitossanitária, doenças causadas por fungos, bactérias e vírus. A espécie Passiflora cincinnata Mast. por apresentar resistência à doença da parte aérea causada pe

32. Development of pollen grain in yellow passion-fruit (Passiflora edulis f. flavicarpa; Passifloraceae)
Visando elucidar os processos que ocorrem durante a formação dos grãos de pólen em maracujá amarelo (Passiflora edulis f. flavicarpa), foram coletados botões em diferentes estádios de desenvolvimento. As anteras foram desidratadas, embebidas em parafina, cortadas a 10 mm e, após a coloração diferencial com safranina e verde rápido, montadas em bá

33. Estudo de um potyvirus isolado de especies de Crotalaria
A virus isolated from Grata/aria species showing the mosaic symptom, preliminarily identified as a potyvirus, was studied. The virus was named Crotalaria mosaic virus. The characteristics studied were: host range, "in vitro" properties, transmission by aphids, seed transmission and different meehanieal transmission methods, eytopathology, serologieal relatio

34. Estudo de carotenoide e pro-vitamina A em alimentos
Many analytical methods have been developed with the purpose of establishing a simple, rapid and economic procedure for determining the provi tamins A in foods. In the present study, three methods were assessed: those of COST91, IVACG and RODRIGUEZ-AMAYA et alii simplied. Kale, carrot, papaya and tomato were chosen as food samples because of their distinct c

36. The Microflora of Frozen Passionfruit Nectar Base1
A considerable and varied microflora is introduced into passionfruit nectar base under present methods of production. In spite of the great acidity of the nectar base (pH range: 2.8 to 3.2), the high sucrose concentration (approximately 50%), and storage at -20 C, remnants of the microflora persist for a year or longer. During storage, however, there is a st
