The cultivation environment influences the physiological quality of stored Sonchus oleraceus L. seeds

Understanding the responses of seeds to detriment interaction external factors is one challenges research, especially with little explored species such as Sonchus oleraceus L. Thus, objective was investigate effect cultivation system, storage time and temperature on physiological potential Seeds were used two systems (organic conventional) in three times (0, 90 180 days) submitted at temperatures (20 30 ºC). For evaluation germination, first count, germination percentage speed index determined, while root length hypocotyl growth determined for seedling growth. The count statistically higher than days both crops temperatures. conventional obtained ºC. There a reduction days, 20 °C. environment influences seed quality during storage.
