Production of crops is troubled by major issues called abiotic stressors. The most important sensitive stages to abiotic stress are during seed germination and seedling growth. Seed priming promotes faster, more synchronised emergence and enhances the performance of seedlings. Different kinds of chemicals are utilised for seed priming today. At the same time the issue of environmental concerns is coming from every corner. Hence organic farming is getting due considerations. The present study was aimed to investigate the effect of matrix priming with biostimulants on germination and seedling quality of carrot seeds under abiotic stress conditions. The experiment was conducted at the Seed Science and Technology Laboratory of Ankara University under controlled conditions. Moisture stress was simulated using PEG-6000 at different concentrations (0, 10 and 15% PEG), while salinity stress was simulated using NaCl at different molarity (0, 50 and 100 mM), which have same osmotic potential with the corresponding PEG concentrations. All matrix priming treatment with biostimulants significantly (P< 0.05) improved performance of seeds and seedlings. Seaweed alone and its combination with butenolide showed the best performance for all the parameters. The GP of non -primed low-quality seeds of carrot at-0.30 MPa was 0% but it was 32% for seeds primed with SW. Likewise, for low quality seeds at 100 mM salt concentration, maximum seedling height of 4.7 cm was recorded in SW while the control was 0 cm. Biostimulants can be used as organic seed priming agent to enhance seed quality.
