Effect of gamma irradiation of some quantitative indices of wheat and the ultrastructure of wheat chloroplasts

Journal Article:

Abstract

The effects were observed of acute gamma irradiation on dry seeds of Triticum aestivum var. erythrospermum (Koern.) Mansf., variety Kosutska, and Triticum monococcum (L.). Gamma radiation doses ranged from 0.258 C.kg/sup -1/ (1 kR) to 5.160 C.kg/sup -1/ (20 kR). Plant samples from pot experiments were analyzed as to the lengths of the first three leaves, production of dry matter and chloroplast ultrastructure. The studied quantitative indices, their variability and correlations are substantially dependent on the genotype of the tested species and on the applied radiation dose. Gamma radiation caused vesiculation and increase of chloroplasts, an increase in the grain number, a decline in the number of disks, a reduction of stroma thylakoids and a grouping of grana in the chloroplasts. The frequency of these changes is significantly influenced by the genotype of the tested species and by the applied radiation dose level.
