Summary
The effect of pre-sowing γ-irradiation of cotton seeds from a point source of Cs137 on emergence, growth, flowering, and yield was studied. High radiation doses caused reduction of emergence, inhibition of growth retardation of flowering, and reduction in number of flowers and bolls produced by the plant. The yield was greatly reduced under high dosages and approached that of the control plants under low dosages. γ-rays caused a marked degree of sterility.
No significant stimulating effect on growth and development was detected when the dry cotton seeds were subjected to γ-irradiation doses of 1.17 to 26.92 kr.
