Monitoring the Changes in Germination Characteristics and Seedling Growth between Storage and Non-storage of Primed Tall Fescue Seed | Chapter 9 | Cutting-edge Research in Agricultural Sciences Vol. 7

 Seeds are normally sown directly in the field or stored for short periods of time in seed priming studies. Priming allows seeds to be hydrated to a degree that allows pre-germination metabolic activity to occur while preventing radicle emergence. After priming, the seeds may be dried back to their original moisture content. The aim of this study was to see how storage affected tall fescue seed that had been primed. The seeds were primed using hydropriming and osmopriming methods in this analysis. For osmopriming, the water osmotic potential was between -1.5 and -2.2 MPa. The seeds were divided into two groups after drying. The seeds in the first group were packed in aluminium foil bags and held at 25°C for up to a year, while the seeds in the second group were used for an un-stored germination test. In most treatments, germination percentage for primed seeds stored at 25°C for 1 year decreased significantly compared to un-stored primed seeds, but the control seeds (stored non-primed seeds) had the lowest germination value when compared to hydropriming for 1 day. The proportion of stored seeds that germinated was found to be slightly lower. Seeds that had been primed but had not been processed had shorter germination times than seeds that had been primed but had not been stored. Hydropriming can be recommended to increase seed germination efficiency without reducing the survival of tall fescue species, according to the findings. Hydropriming was known to increase germination efficiency without sacrificing durability among all priming treatments. Following storage conditions of F. arundinacea, hydropriming as a physiological treatment improved seed efficiency.
