1. In vitro germination to overcome dormancy in seeds of ‘Red Globe’, ‘Italia’ and ‘Niagara Rosada’ grapes
Resumo A dormência em sementes de videira dificulta o avanço de muitos programas de melhoramento genético da cultura, ocasionando desuniformidade e baixa porcentagem de germinação. Os métodos convencionais utilizados para superar a dormência são demorados. Assim, a germinação in vitro das sementes torna-se uma alternativa promissora para garantir

4. Pre-Harvest Desiccation in Productivity and Physiological Quality of Cowpea Seeds
RESUMO: A dessecação pré-colheita é uma estratégia importante no sentido de antecipar a colheita, evitando que a semente fique no campo em condições climáticas desfavoráveis. No entanto, pouco se sabe sobre o uso de dessecantes e as épocas de aplicação destes na cultura do feijão-caupi (Vigna unguiculata). Objetivou-se neste trabalho avaliar efe

5. Vigor-S, a new system for evaluating the physiological potential of maize seeds
ABSTRACT: The refinement of vigor tests and the possibility of utilizing computer resources for the effective evaluation of the seed physiological potential have attracted considerable interest from research and seed technologists. The aim of this study was to evaluate the physiological potential of maize seeds using the newly-created Automated Analysis of S

6. Use of the software Seed Vigor Imaging System (SVIS®) for assessing vigor of carrot seeds
ABSTRACT Seed vigor has traditionally been evaluated by physiological, biochemical and stress tolerance tests. More recently, with the use of computerized image analysis, objective information has become accessible in a relatively short period of time, with less human interference. The aim of this study was to verify the efficiency of computerized seedling i

7. Swingle citrumelo seed vigor and storability associated with fruit maturity classes based on RGB parameters
ABSTRACT: Citrus seeds normally have low storability. Identifying an optimal fruit harvest time for production of high vigor seeds is important for nurseries; however, identifying this stage for Swingle citrumelo fruits has been based only on visual color examination, and research related to this parameter has been inconsistent. The main objective of this st

10. Staging coffee seedling growth: a rationale for shortenning the coffee seed germination test.
The species Coffea arabica L. is one of the most important agricultural commodities in Brazil. Despite considerable effort at vegetative propagation of coffee plants, they still are propagated by seedlings produced directly from seeds. An undesired trait of coffee seeds is that they have slow and asynchronous germination, which makes it difficult to obtain s

12. Priming in sunflower achenes, under termic and droguht stresses. / Condicionamento fisiológico de aquênios de girassol, sob estresses térmico e hídrico.
Sunflower production may be influenced by plant density, requiring uniformity in the initial growth phase. This may be influenced by water availability, as well as by soil temperature from germination through emergence. The priming technique has been used to reduce the period between germination and seedling emergence in the filed, providing better performan
