Sunflower hybrids, SF-270, PARC-92E, SF-187,VYP, AA-8140, SMH-9501, LG-5410, and SMH-221 were compared for water imbibition for 0, 6, 12, 18, 21, and 24 hours and germination. Germination potential and speed were decreased by pre-soaking the seed. By drying the seed after soaking, it attained its original germination potential whereas germination speed increased with increasing soaking time before drying.
