1. Advances in vegetative propagation of Olive tree
Resumo No Brasil é crescente o interesse pela cultura da oliveira, especialmente naquelas regiões consideradas aptas ao cultivo, onde se têm ocorrência de baixas temperaturas entre 8ºC e 10ºC no período que antecede a floração. As áreas com estas características estão localizadas, principalmente, nas regiões Sul e Sudeste do país, caracterizad

2. Analysis of VRN1 gene in triticale and common wheat genetic background
In cereals, the transition from the vegetative stage to flowering is controlled in the main by the set of vernalization genes. Within these genes the most important role is played by VRN1, which encodes a MADS-box transcription factor, regulating the transition of shoot apical meristem to the reproductive phase. The level of vernalization requirement is stro

3. Indução floral de Beta vulgaris L. em condições do Distrito Federal
The demand for beet seeds in Brazil is growing every year, however, the dependence on imported seeds of this vegetable is almost total. Low temperatures associated with long photoperiods promote flowering and seed production, but this conditions are rare in most of Brazil. The artificial vernalization of roots is a good technique for seed production of vario

4. Caracterização genética e molecular de fatores associados a resposta à vernalização para o florescimento em aveia / Genetics and molecular characterization of factors associated to vernalization response of flowering time in oat
O florescimento é um fator decisivo à adaptação da aveia em ambientes subtropicais. A iniciação floral em alguns genótipos cultivados no Sul do Brasil é dependente de baixas temperaturas, um processo denominado vernalização. Os objetivos deste trabalho foram determinar o número de genes que controlam o caráter resposta à vernalização em aveia,

5. MODELING DEVELOPMENT AND SOIL WATER BALANCE IN WHEAT / MODELAGEM DO DESENVOLVIMENTO E DO BALANÇO DE ÁGUA NO SOLO EM TRIGO
Wheat is the main winter crop in Rio Grande do Sul State. Temperature and photoperiod are the major environmental factors that control development in wheat. Wheat plants exposed to cold, non freezing temperatures induce them to enter the reproductive phase. Temperature and photoperiod response functions are used to simulate the wheat development. Development

6. VERNALIZATION AND GIBBERELLIC ACID IN THE GERMINATION AND DEVELOPMENT OF Penstemon digitalis cv HUSKER RED / VERNALIZAÇÃO E APLICAÇÃO DE ÁCIDO GIBERÉLICO NA GERMINAÇÃO E DESENVOLVIMENTO DE Penstemon digitalis cv HUSKER RED
Penstemon digitalis cv Husker Red has showy flowers that have the potential to be cultivated as garden flowers as well as cut flowers. Two studies were conducted in Lincoln NE, USA. The first study was carried out to determine if treating plants of Penstemon digitalis cv. Husker Red with gibberellic acid (GA3) and vernalization (cold) periods would produce t

7. Absorption march of nutrients and productivity in vernalized garlic originated from tissue culture under nitrogen and molybdenum doses / MARCHA DE ABSORÃÃO DE NUTRIENTES E PRODUTIVIDADE EM ALHO VERNALIZADO PROVENIENTE DE CULTURA DE MERISTEMAS SOB DOSES DE NITROGÃNIO E MOLIBDÃNIO
The objective of this study was to evaluate the growth and absorption of nutrients in vernalized garlic originated from tissue culture and the response to the application of different topdressing nitrogen doses and molybdenum doses applied by foliar dressing. Three experiments were conducted on field conditions in the Sector of Horticulture of the Federal Un

9. A genetic framework for flowering-time pathways in Citrus spp.
Floral transition is one the most drastic changes occurring during the life cycle of a plant. The shoot apical meristem switches from the production of leaves with associated secondary shoot meristems to the production of flower meristems. This transition is abrupt and generally irreversible, suggesting it is regulated by a robust gene regulatory network cap

10. Efeitos do estresse hÃdrico no controle do superbrotamento e na produtividade do alho vernalizado. / Water stress effects in the control of the secondary bulb growth and in the vernalizated garlic productivity.
The secondary bulb growth is the genetic-physiologic anomaly causing more damages in the culture of the garlic, affecting, mainly, the bulbs commercial production. The excess of water in the bulbification time, it has been pointed out the main factors that contribute to the occurrence of this abnormality. Irrigation suspension during the bulbification time,

12. Differential Regulation of FLOWERING LOCUS C Expression by Vernalization in Cabbage and Arabidopsis1
Vernalization is required to induce flowering in cabbage (Brassica oleracea var Capitata L.). Since FLOWERING LOCUS C (FLC) was identified as a major repressor of flowering in the vernalization pathway in Arabidopsis (Arabidopsis thaliana), two homologs of AtFLC, BoFLC3-2 and BoFLC4-1, were isolated from cabbage to investigate the molecular mechanism of vern
