The effect of calcium and magnesium on the radiosensitivity of Wolffia arrhiza (L.) Wimm.

Jan Sarosik, Hanna Wożakowska-Natkaniec

Abstract


After irradiation with gamma radiation from 60Co, differences were found in the survival rates of Wolffia arrhiza (L.) Wimm., cultured in vitro with different amounts of calcium and magnesium. Radiation doses ranged from 80 to 3000 mC•kg-1. Magnesium and especially calcium increased the resistance of Wolffia to acute radiation. This was expressed by the survival of the plants cultured in mediums supplemented with calcium and magnesium after receiving doses of 1200 and 3000 mC•kg-1 while plants cultured in basic medium already showed absolute mortality (DL 100) at exposition to 800 mC•kg-1. Radiosensitivity of Wolffw arrhiza is high compared with other species from the Lemnaceae family.
