e0“The thermal and fast neutron irradiations of dormant seeds of Triticum monococcum flavescens”
e3“There was almost no germination at 37.5×1012nth/cm2 of thermal neutrons and at 5krad fast neutrons. Even at about 30×1012nth/cm2 and at 2.5krad the seedlings did not grow and died in early stage”

Other claims from this paper (11)
- Intervention effect Higher neutron dosage more delayed germination and growth of wheat seedlings.
- Intervention effect Higher dosage reduced survival rate, height of mature plants and seed fertility.
- Intervention effect Seedlings did not grow and died early at about 30×1012nth/cm2 and at 2.5krad.
- Intervention effect About 2×109nth/cm2 of thermal neutrons produces 1r equivalent effects of X-rays on seedling length and seed fertility.
- Intervention effect The 1r equivalent effects of thermal neutrons on chromosome aberrations and chlorophyll mutations occur at about the order of 109nth/cm2.
- Intervention effect Frequency of chromosome aberrations and chlorophyll and other mutations increased with increasing dosage.
- Intervention effect Relative biological effectiveness of fast neutrons to X-rays for germination rate was 4.
- Intervention effect Relative biological effectiveness of fast neutrons to X-rays for seedling length was 10.
- Intervention effect Relative biological effectiveness of fast neutrons to X-rays for seed fertility was 12.
- Intervention effect Relative biological effectiveness of fast neutrons to X-rays for chromosome aberrations was 8.
- Intervention effect Relative biological effectiveness of fast neutrons to X-rays for chlorophyll mutations was 10.
