Abstract:
OBJECTIVETo provide the radiation-induced technical reference and theoretical basis for safflower and other medicinal plants.
METHODSeeds of Carthamus tinctorius were irradiated with 60Cogamma-ray, and germination rate of seeds, germination, seedling rate and seedling height, root length, fresh weight, root activity and peroxide catalase (CAT), peroxidase (POD), superoxide dismutase (SOD) activity were determined.
RESULT AND CONCLUSIONThe LD50 of radiation dose is about 300 Gy, effects of seeds irradiation with 6Co-gamma-ray on shoot growth and physiological status of C. tinctorius are obtained.
