Viability and storage of seeds of Xylosma ciliatifolia
Abstract
Xylosma ciliatifolia (Clos) Eichler is a wood species, is a native wood species from Brazil. This study aimed to identify seed viability and seed longevity under storage in two environments. Seeds from fresh fruits were collec- ted and subjected to water content determination, germination tests in different thermal regimes and substrates, and emergency in greenhouse conditions. Samples stored in cold chamber (5±2 °C and 80 % RH air) and dry chamber (17±2 °C and 45 % RH air) were subjected to periodic viability tests in germination chamber and evaluated concerning emergency in greenhouse. Initially, the germination in controlled environment and the emergence in greenhouse were among close to 95 % and 80 %, with average times of six and 12 days, respectively. Seeds of X. ciliatifolia presented high viability and storage in dry chamber allowed the conservation of viability for longer.
