EFFECT OF GIBBERELLIC ACID ON GERMINATION AND SEEDLING GROWTH OF BARLEY UNDER NACL-INDUCED SALINITY

Abstract

Barley is a widely cultivated grain in the world. Barley is widely used in both human and animal nutrition. Uniform germination is one of the critical factors affecting yield. Salinity is one of the most common abiotic stress factors in the world. In recent years, various seed coating processes have provided more uniform germination of seeds. This study investigated the response of different doses of gibberellic acid applications to salt stress. Germination percentage, shoot, root length, and wet and dry weight data were analyzed. The study used two widely used barley varieties (Anka 06 and Cirit). Control, 5 and 10 EC were used as salt dose, and control, 100 and 200 ppm were used as gibberellic acid. As a result of the study, gibberellic acid positively affected germination data in both varieties at increasing salt doses.
