This study has been carried out using the onion and pepper seeds to
determine the effects of the aqueous medium temperature, during treatment
with oxygen, on the germination percentage seed vigor and for determining the
period needed for the treat
ment with the oxygen as well.
The treatment period has taken ١٢-٣٦ hours according to the kind of crop
and the medium temperature, which varied between ١٠-٣٠ °C.
Results of the study indicated that the treatment of seeds with oxygen, in an
aqueous medium, improved the germination percentage and the seed vigor. The
period needed for the treatment of the seeds with oxygen differs according to
the kind of crop and the temperature of the medium and varies between ١٨-٢٤
hours with respect to the onion seeds, and between ٢٤-٣٦ hours regarding the
pepper seeds. The period needed for treatment with oxygen decreases with the
rise of temperature.
