| Summary: | The controlled deterioration test has frequently been used to evaluate the vigor of several species and could be an alternative for evaluation of the vigor in jilo seeds. The objective of the present work was to study the controlled deterioration to evaluate the physiological quality of jilo seeds. Five seed lots, cv. Verde Claro Comprido, were submitted to tests of germination, germination first count, seedling emergence and deterioration (19%, 21% and 24% water content, at 45ºC and 24 and 48 hour periods). The 24% water/24h at 45ºC combination, for the controlled deterioration test, was efficient to detect vigor differences among jilo seed lots. |
