ABSTRACT: Accelerated aging is one of the most useful tests used for the evaluation of seed vigor but it is
seldomly used to test melon (Cucumis melo L.) seeds. The objective this research was to compare different
procedures of the accelerated aging test to evaluate the physiological quality of melon seeds and the efficiency
of using saturated salt solution for the control of water uptake by seeds. Five seed lots each of the hybrids AF-
646 and AF-682 were tested for germination, seedling emergence, traditional accelerated aging (periods 0f
48, 72 and 96 hours, at 38 or 41°C) and salt saturated accelerated aging. The accelerated aging test (traditional
procedure and with salt solution) for 72h and 96h, at 38 or 41°C was sensitive to detect differences in the
physiological quality of the seeds. It was also observed that the seed water content after salt saturated
accelerated aging was lower and more uniform, thus presenting advantagens in relation to the traditional
procedure.
Key words: Cucumis melo, physiological quality, vigor
