1. Seed reserves reduction rate and reserves mobilization to the seedling explain the vigour of maize seeds
Resumo: Compreender como a dinâmica de reserva ocorre durante a germinação e formação de plântulas é determinante para avanços na tecnologia de sementes. Objetivou-se com este trabalho verificar qual temperatura de envelhecimento acelerado é mais eficaz para separar níveis de vigor de sementes de milho e avaliar a dinâmica de reservas durante o pr

2. Reserve metabolism of stored and germinated Araucaria angustifolia seeds
ABSTRACT. Germination metabolism of recalcitrant seeds of Araucaria angustifolia is activated in storage, which complicates the seeds conservation and utilization. This study aimed to identify the changes in the reserve metabolites of A. angustifolia seeds throughout storage in order to understand the processes of hydrolysis caused by germination metabolism.

3. Fructan dynamics in the underground organs of Chresta exsucca (Asteraceae), a dry season flowering species
ABSTRACT Climatic seasonality has an influence on the phenology of native Cerrado plants. Herbs and subshrubs tend to flower in the rainy season, although some species of these habits flower in the dry season. Reserve carbohydrates, stored in the underground organs, are used to support phases of high energy-demand, but also may protect plants from damage dur

4. Enzyme activity and reserve mobilization during Macaw palm ( Acrocomia aculeata ) seed germination
ABSTRACT Reserve mobilization in seeds occurs after visible germination, which is marked by the protrusion of the radicle or cotyledonary petiole, as in species of Arecaceae. Acrocomia aculeata (macaw palm), usually produces hard seeds whose endosperm has mannan-rich cell walls. We investigated the composition of storage compounds in macaw palm seed and the

6. Seed reserve composition and mobilization during germination and early seedling establishment of Cereus jamacaru D.C. ssp. jamacaru (Cactaceae)
Cereus jamacaru, uma cactácea encontrada comumente no nordeste brasileiro, é amplamente usada como planta forrageira e como ornamental e medicinal. No entanto, existem poucas informações sobre os aspectos fisiológicos e bioquímicos relacionados à sua germinação. O objetivo desse estudo foi avaliar a mobilização de reservas durante a germinação e

7. Estresse salino e mobilizaÃÃo de reservas cotiledonares durante a germinaÃÃo e estabelecimento da plÃntula de cajueiro anÃo-precoce / Salt stress and reserve mobilization in cotyledons during germination and seedling establishment of precocious-dwarf cashew
This study aimed to obtain basic information on seed germination and seedling establishment of dwarf-precocious cashew (Anacardium occidentale L.) under saline conditions and the relationship between salinity and reserve mobilization during these processes. BRS 189 seeds (cashew nuts) were sown in plastic trays containing vermiculite moistened with distilled

8. Fisiologia, bioquÃmica e morfologia da germinaÃÃo de mandacaru (Cereus jamacaru D.C.) / PHYSIOLOGY, BIOCHEMISTRY AND MORPHOLOGY OF MANDACARU (Cereus jamacaru D.C.) GERMINATION
The aim of this work was to study the physiology, biochemistry and morphology of mandacaru (Cereus jamacaru D.C) germination. Firstly, we analyzed the effects of light and temperature on mandacaru germination under four light treatments (white, dark, red and far-red) associated to six different temperatures [15, 20, 20-30 (alternated), 25, 30 and 35ÂC]. The

11. Fructan metabolizing enzymes in Vernonia herbacea (VELL.) Rusby. / Enzimas do metabolismo de frutanos em Vernonia herbacea (VELL.) Rusby.
The occurrence of fructans has been reported in native species of a cerrado area of Reserva Biológica e Estação Experimental de Moji Guaçu. Vernonia herbacea, one of these species, presents underground organs named rhizophores which accumulate fructans of the inulin type as reserve carbohydrate. The seasonal growth pattern exhibited by plants of V. herba

12. Proteinas cotiledonares de soja : detecção "in situ" e mobilização durante a germinação
Seeking to study the various changes in the protein content in seeds of Glycine max during germination, a series of general and cytochemical techniques was performed in order to study the protein bodies of this legume "in situ",verifing the presence of these bodies in the cotyledon cells by hematoxilin-eosin and xylidine-ponceau stains and silver impregnatio
