Effect of gamma radiation on starch content and cellular morphology of Chlorella pyrenoidosa; Efecto de la radiacion gamma sobre el contenido en almidon y la morfologia celular de Chlorelia pyrenoidosa

Abstract

The effect of five doses of gamma radiation (10, 100, 500, 1000 and 5000 Gy) on starch content and fine structure of Chlorella pyrenoidosa has been studied. Results show the accumulation of large amounts of starch on Chlorella cells after irradiation at 500, 1000 and 5000 Gy doses. The starch which is stored in the cytoplasm in form of great grains produces a de organization of the chloroplast structure, observed by electron microscopy techniques. The microphotographs presented also show a significant increase in the cellular size after irradiation up to 500 Gy. (Author) 29 refs.
