13. Initial root length in wheat is highly correlated with acid soil tolerance in the field
ABSTRACT: In acid soils, toxic aluminum ions inhibit plant root growth. In order to discriminate aluminum (Al) tolerance, trustful screening techniques are required. In this study, 20 wheat cultivars, showing different levels of Al tolerance, were evaluated in a short-term soil experiment to access their relative root length (RRL). Moreover, the alleles of t

14. Chemistry Inspired by the Colors of Fruits, Flowers and Wine
ABSTRACT An overview is provided of the status of research at the frontiers of investigation of the chemistry and photochemistry of two classes of natural plant pigments, the anthocyanins and the betalains, as well as of the pyranoanthocyanin pigments formed from anthocyanins during the maturation of red wine. Together, anthocyanins and betalains are respons

15. Sugars levels of four sugarcane genotypes in different stem portions during the maturation phase
ABSTRACT Maturation is a characteristic of sugarcane plant (Saccharum spp.) and even when grown under the same soil and climate conditions the varieties differ on the maturation curve. Thus, studies that allow establishing maturation curves of different sugarcane genotypes in the local soil and climate may indicate the proper harvesting period to ensure bett

16. Recurrent Somatic Embryogenesis and Plantlet Regeneration in Psidium guajava L.
A simple and efficient protocol for recurrent somatic embryogenesis and plant regeneration is one of the prerequisites for genetic improvement of guava. An efficient reproducible regeneration somatic embryogenesis protocol was developed in four genotypes of Psidium guajava L. using immature zygotic embryo as starter explant. Somatic embryogenesis induction w

17. Somatic embryogenesis in Acrocomia aculeata Jacq. (Lodd.) ex Mart using the thin cell layer technique
Considering the necessity of Acrocomia aculeata propagation for large-scale production, the aim of this study was to establish a somatic embryogenesis protocol using the thin cell layer (TCL) technique. Aerial parts of in vitro plants were transversally cut at the base into eight TCLs and placed in a culture medium for callus induction. The induction medium

18. Leaf gas exchange and yield of three upland rice cultivars
Studies of physiological parameters associated with crop performance and growth in different groups of upland rice (Oryza sativa L.) may support plant breeding programs. We evaluated the role of gas exchange rates and dry matter accumulation (DMA) as traits responsible for yields in a traditional (cv. ‘Caiapó’), intermediate (cv. ‘Primavera’) and mo

19. Dynamic accumulation of sesquiterpenes in essential oil of Pogostemon cablin
Sesquiterpenes Essential oil produced by patchouli was one of the most important naturally occurring base materials used in the perfume industry, containing various sesquiterpenes. Three different parts (leaves, stems and roots) of Pogostemon cablin (Blanco) Benth., Lamiaceae, were profiled in relation to different maturation phases in this paper, evaluating

20. Caracterização do proteoma de entrenós maduros e imaturos de cana-de-açúcar durante o estádio de maturação / Characterization of the proteome of mature and immature internodes from sugarcane during maturation phase of development
Grandes esforços dos programas de melhoramento genético da cana-de-açúcar são dedicados ao desenvolvimento de novas variedades com maior rendimento e conteúdo de sacarose. As etapas do metabolismo da sacarose têm sido foco de pesquisas há muito tempo, porém apenas recentemente têm-se buscado compreender os processos de transporte e acúmulo da saca

21. Avaliação de doze cultivares de laranja doce de maturação precoce na região sudoeste do Estado de São Paulo. / Evaluation of twelve early maturing sweet orange cultivars in the southwestern São Paulo State
The number of sweet orange cultivars used in commercial orchards in Brazil is restricted, although the diversity of genera, species, cultivars and clones of citrus is great. However, the industrial processing is based on four main cultivars, the \ Hamlin\ , as early maturing, the \ Pera\ , as mid-season, and \ Natal\ and \ Valencia\ as late maturing cultivar

22. Ocorrência, distribuição geográfica e estudo fenológico de camu-camuzeiro (Myrciaria dubia (H.B.K.) Mc Vaugh no estado de Roraima / Occurrence, geographical distribution and phenological study of (Myrciaria dubia (H.B.K.) McVaugh) in the state of Roraima
The camu-camu (Myrciaria dubia) is a representative of the family Myrtaceae, one of the botanical families most important to fruit growing and which is part of several communities of the Brazilian vegetation. M. dubia is an Amazonian plant, found most often in the Peruvian Amazon. The species possesses fruits with a high content of vitamin C, the pulp being

23. Produção recombinante e caracterização funcional de uma legumaína de cana-de-açúcar
Plant legumains, also termed vacuolar processing enzymes (VPEs), are cysteine peptidases that play key roles in seed maturation, germination, senescence, stress response, programmed cell death during development and defense against pathogens. Despite the increasing number of reports on VPEs, most of studies are on dicotyledonous legumain and their role in se

24. Water potential and viability of seeds of Eugenia (Myrtaceae), a tropical tree species, based upon different levels of drying
The aim of the present work was to study the water potential and viability of Eugenia based upon different levels of drying. The seeds showed high water content at shedding and were sensitive to desiccation; however, the level of this sensitivity (water content) varied among the species. Five target drying levels were defined according to the critical levels
