Groundnut Seed Resistance to
High Temperatures
Y. Jacob and P. Baujard 1
A preliminary study was carried out to evaluate the effect of high temperatures on the
germination performance of groundnuts in an effort to develop a technique to eradicate virus
in groundnut seeds.
Findings show that groundnuts can endure of 60°C-70°C for 20 minutes, 78.5° C for 10
minutes and 80°C-90°C for 5 minutes without losing their capacity to germinate.
Groundnut seeds therefore, can endure high temperatures. A study of the behavior of
viruses present in the seeds at such high temperatures should provide information on the
usefulness of this method to disinfect groundnut seeds.
