^60Co-γ射线辐照对大蒜试管苗增殖、生长及抗氧化特性的影响

0

TL;DRAbstract

Using the in vitro plantlets from anthotaxy of garlic variety Ershuizao'as material, effect of different dosage radiation to the plantlets were studied in this paper. The results showed, with 0~16 Gy radiation dos ages there is no death in garlic plantlets. Subter1Gy radiation have unapparent effect to garlic plantlets, radiations more than 4Gy led to restrain of proliferation and growth of plantlets, restraining degree enhanced a long with the increasing dosages. Simultaneity, radiations also influence generation rate of superoxide radical (O2(superscript -)), activities of superoxide dismutase (SOD), peroxidse (PODD) and ctalase (CAT) of garlic plantlets.
