تأثیر پیش تیمار پر اکسید هیدروژن (H2O2) بر تحمل به تنش شوری در تریتیکاله و گندم در مرحله جوانه‌زنی

Increasing salinity is a major problem in crop production. Select an appropriate pretreatment, the initial establishment of plant seeds can be effective under salt stress and tolerance to salinity. In this study, in two separate trials of different concentrations of hydrogen peroxide as pretreatment with triticale and wheat seed, then its effect on germination changes imposed by the lack of salt was studied. Triticale seed germination rate and pretreatment with hydrogen peroxide in the use of both salt concentration of 60 mM sodium salt of about 27 % over the 80 mM salt. While hydrogen peroxide pretreatment effect on seed germination of wheat, 80 and 120 mM salt is not. Under salinity triticale seeds pretreated with a lower concentration of hydrogen peroxide increased root elongation were greater. While hydrogen peroxide in salinity in wheat roots length did not change. Therefore, the results obtained by soaking the seeds in hydrogen peroxide before germination under saline conditions can be somewhat salinity control.
