ZINK, Eduardo  and  MENDONCA, Nelson Teixeira de. The influence of humidity and temperature on viability of watermelon seeds in storage. Bragantia [online]. 1964, vol.23, n.unico, pp.343-350. ISSN 0006-8705.

The viability of watermelon seeds kept under different storage conditions, was studied during a period of 18 months. The experimental results presented in this paper drew the following conclusions: 1)  Complete viability at the end of 18 months was obtained for seeds stored at 20°C and at relative humidity of 45%. 2)  At this same temperature, the longevity of the seeds decreased with the increasing of relative humidity. 3)  Seeds kept at 30°C, even in low relative humidity condition, lost their viability in a short time. 4)  The seeds of watermelon stored in airtight containers at room temperature, kept their viability well for 12 months, after which time it decreased considerably.
