Out of priming treatments, incubate seeds under 15 and 25 ◦C,
accelerated germination rate and T10–90 to the largest extent. Only
at 25 ◦C treatment observed an adverse effect on FGP (Table 1).
Radicle and plumule length of cumin seeds were significantly
affected by interaction between prime and temperatures. Radicle
and plumule length of cumin seeds were significantly longer in PS
compared to UPS under 10 and 15 ◦C. Vigor index was not different
(p > 0.05) under any of the three levels of temperature in prime and
unprimed cumin seeds (Table 1). None of the applied methods of
priming and incubation temperatures improved seed vigor.
