Potencial fisiológico de sementes de Helianthus annuus L. em função do acondicionamento: tipo de embalagem na qualidade fisiológica e sanitária de sementes de girassol

Abstract

Assuming that there are limitations in the process of storage and use of different types of packaging used for the storage of seed for farmers, it is necessary to study reviews changes in seed quality. Thus, this study aimed to evaluate the influence of different packaging in maintaining physiological and sanitary quality of seeds of two cultivars of sunflower as an alternative for medium and small farmers. Was used for the analyzes seed lots of cultivars Catissol and Embrapa 122, plus packaging Pet bottle, aluminum can and plastic bag. Tests included: water content, germination (first count and normal seedlings), electrical conductivity, cold test, accelerated aging, tetrazolium, seedling emergence in the greenhouse, field seedling emergence, speed of emergence index (IVE), seedling vigor (root length and hypocotyl and seedling dry weight) and sanity. The germination, vigor and health are effective in assessing the physiological seed; packaging Pet bottle, aluminum can and plastic bag differ in conservation of physiological and sanitary quality of sunflower seeds; Pet bottle being the most suitable for the conservation of seeds until 60 days after storage under the conditions tested.
