Abstract

Sorghum (Sorghum bicolor (L.) Moench) is a C4 plant of the Gramineae family, included in the content of one-year, warm climate cereals. In general, it is widely cultivated in semi-arid and arid regions. In the study, under osmotic stress conditions, the seeds of the Öğretmenoğlu-75 variety were divided into small, medium and large. Seven different PEG 6000 concentrations of 0-5-10-15-20-25-30% were used to create osmotic stress and their effects on seed germination and seedling growth were investigated. In the study, germination power, average germination time, root and seedling length, root and seedling fresh weight were measured and calculated. In all genotypes studied, decreasing seed size and osmotic potential increased mean germination time and decreased germination vigor, root and seedling length. As a result of the research, it was determined that germination and seedling development of large seeds were better than small seeds under abiotic stress and poorly prepared seedbed conditions.
