Effect of ultra-violet radiation on the ultrastructure of meristematic root cells of barley (Hordeum vulgare L.)



Effect of ultra-violet radiation on the ultrastructure of meristematic root cells of barley (Hordeum vulgare L.)



Studii si Cercetari de Biologie, Biologie Vegetala 30(1): 3-6



Ulstrastructure of roots from germinated barley seed was investigated 2, 5 and 10 min after irradiation with UV light. Irradiation gave partial destruction of chromatin in the nucleus, vacuoles were formed in the nucleolus and it became irregular in shape. Mitochondria swelled and the system of cristae showed changes. Vacuolar degradation was found in the cytoplasm.
