Abstract
In order to study the effects of gamma rays on germination indices i.e. germination index (GI), total germination (GT) and thegermination energy (GE), of maize hybrid, Turda Star current experiment was conducted. Dry seeds of Turda Star maize hybrid wereirradiated with 2, 5, 15, 30 and 50 Gy, using a 60Co-gamma radiation source.Results showed that gamma irradiation affected all the above mentioned parameters except germination percentage. Totalgermination and germination energy was significantly affected at higher doses of gamma rays. However, increasing doses of gammarays did not have significant effects on seed germination percentage. The other growth parameters showed declining tendency withincreasing doses of gamma irradiation.

Nuclear techniques, in contrast to conventional breeding techniques, are widely applied in agriculture for improving genetical diversity
Dry seeds of Turda Star maize hybrid were treated with different doses of gamma rays irradiated with different doses of gamma rays (2, 5, 15, 30 and 50 Gy), using a 60Co gamma radiation source emitting at 5,72 Gy/h rate at Babes-Bolyai University, Physics Faculty, from Cluj- Napoca, Romania
This investigation was carried out to study the relation between different doses of gamma radiation, seed germination and development of maize hybrid Turda Star
Summary
In contrast to conventional breeding techniques, are widely applied in agriculture for improving genetical diversity. Basic tool of nuclear technology for crop improvement is the use of ionizing radiation which causes induced mutations in plants. Gamma rays generally influence plant growth and development by inducing cytological, genetical, biochemical, physiological and morphogenetic changes in cells and tissues (Gunckel & Sparrow, 1961).
