1. Torsion of canes and hydrogenated cyanamide in bud bursting and production of grapevine cv. Itália muscat in the São Francisco valley
Resumo A videira cultivada em regiões tropicais, como o Submédio do Vale do São Francisco, exibe forte dormência de gemas e dominância apical, havendo a necessidade da utilização de produtos que promovam a quebra de dormência das gemas. O presente trabalho teve como objetivo avaliar a eficiência da aplicação de cianamida hidrogenada e da prática

2. Action of Essential Oils on Sprouting of Non-Dormant Potato Tubers
ABSTRACT The breakdown of dormancy and early sprouting is one of the main causes of losses of stored potatoes. Sprouting control becomes important especially when tubers are submitted to long-term storage for further processing by the potato industry. The objective of this work is to evaluate the effect of organic sprout inhibitors, eugenol and menthol essen

3. Tipos de poda em pepino dos grupos aodai, japonês e caipira
A poda de ramas em plantas da família Cucurbitaceae é prática bastante controvertida e tem sido questionada por técnicos e produtores que buscam informações sobre a melhoria da produção de frutos, em pepineiro tutorado e cultivado a campo. Neste experimento, avaliou-se produtividade de frutos de três híbridos de pepino, com tutoramento vertical e d

4. Controle do desenvolvimento vegetal pela interação auxina-citocinina. Uma nova abordagem baseada no estudo de mutantes de tomateiro (Solanun lycopersicum cv Micro-Tom) / Control of plant development by auxin-cytokinin interactions. A new approach based on tomato (Solanum lycopersicum cv Micro-Tom) mutants.
The plant hormones auxin and cytokinin are crucial for plant development, since they control cell division, expansion and differentiation, which regulate developmental processes starting from embryo formation to fruit ripening and senescence. Auxins and cytokinins usually regulate the same physiological responses, suggesting multiple mechanisms of interactio

5. PropagaÃÃo vegetativa e seminÃfera de pitaia (Hylocereus undatus (Haw.) Britton &Rose) / Seed and vegetative propagation of Dragon Fruit (Hylocereus undatus (Haw.) Britton &Rose)
The intent of this research was to expand knowledge in relation to the propagation of pitaya (Hylocereus undatus (Haw.) Britton &Rose). The main objective was to elucidate forms of propagation of this fruitful cactus which has been commercially explored. There are very few bibliographical citations and available publications related to the subject directed t

6. Ocorrência e diversidade de ácaros (Acari, Arachnida) associados a Tabebuia roseo-alba (Ridl.) Sand (Bignoniaceae), no município de São José do Rio Preto, São Paulo, Brasil
This study reports the mite fauna associated with Tabebuia roseo-alba, a native and ornamental tree, determining the abundance and seasonal occurrence of species and the diversity of the community. Twenty three species were found belonging to 11 families, 10 of predatory habits and five phytophagous. The food habits of the eight remaining species are not kno

7. Estudo sobre o controle da brotação das gemas epifilas em Bryophyllum Calycinum
It was studied the control of the epiphyllous buds development in Bryophyllum calycinum. The epiphyllous buds exhibit dormancy and the results suggest that the bud development is controlled by endogenous factors. he epiphyllous buds imediately grow up when apex and lateral buds are removed, showing an apical dominance on them. Exogenous hormones like auxins

8. Aspectos fisiologicos e biometeorologicos relacionados com a tecnica de mini-enxertia da seringueira (hevea spp.)
With the aim of contributing for the technical viability of rubber tree mini-grafting, studies were developed concerning some physiological and biometeorological aspects related to sprout production for grafting and the behaviour of the grafted plants under field conditions. Some aspects of the mini-grafting technics were altered, including modifications on

9. The Role of Gravity in Apical Dominance 1: Effects of Clinostating on Shoot Inversion-Induced Ethylene Production, Shoot Elongation, and Lateral Bud Growth
Shoot inversion-induced release of apical dominance in Pharbitis nil is inhibited by rotating the plant at 0.42 revolutions per minute in a vertical plane perpendicular to the axis of rotation of a horizontal clinostat. Clinostating prevented lateral bud outgrowth, apparently by negating the restriction of the shoot elongation via reduction of ethylene produ

10. Uncoupling Auxin and Ethylene Effects in Transgenic Tobacco and Arabidopsis Plants.
Overproduction of auxin in transgenic plants also results in the overproduction of ethylene. Plants overproducing both auxin and ethylene display inhibition of stem elongation and growth, increased apical dominance, and leaf epinasty. To determine the relative roles of auxin and ethylene in these processes, transgenic tobacco and Arabidopsis plants expressin

11. Auxin Dynamics after Decapitation Are Not Correlated with the Initial Growth of Axillary Buds1
One of the first and most enduring roles identified for the plant hormone auxin is the mediation of apical dominance. Many reports have claimed that reduced stem indole-3-acetic acid (IAA) levels and/or reduced basipetal IAA transport directly or indirectly initiate bud growth in decapitated plants. We have tested whether auxin inhibits the initial stage of

12. An Excellent Source of Vegetative Buds for Use in Plant Hormone Studies on Apical Dominance
When studying the role of plant hormones in the control of growth at apical meristems, it is often difficult to obtain needed amounts of physiologically uniform buds. A source and method are described for obtaining sufficient quantities of large, uniform buds and for the treatment of the buds with indoleacetic acid and kinetin. Buds from the root system of E
