“…Rapid seedling growth is an essential phase of turf grass culture and is a key attribute for weed competition and a rapid turf cover. The seed-producing capacity of two varieties of meadow fescue, S215 and S53, correlated well with the rapidity of seedling establishment (Lewis, 1968). Considering tall fescue seeds, a significant germination increase occurred between 30 and 60 DAH (8 and 6% for the f irst and the f inal count, respectively), indicating the start of dormancy loss (Table 1, Fig.…”

After-ripening is a complex enzymatic and biochemical process resulting in the breakage of non-deep physiological dormancy. The experiment was set up to identify the minimum duration of storage after harvest for completion of afterripening in meadow (Festuca pratensis Huds.), tall (Festuca arundinacea Schreb.) and red fescue (Festuca rubra L.). The seeds were stored under ware-house conditions for 0, 30, 60, 90, 120, 150, 180, 210 and 240 days after harvest (DAH). After the storage periods, the seeds were tested for germination and the primary root length, shoot length and seedlings biomass were measured. The final counts in all three species amounted to 60-65% germination immediately after harvest, suggesting a medium level of embryonic dormancy. The after-ripening during storage improved the final germination in all three species with decreasing intensity. In meadow fescue, the final germination was significantly improved up to 150 DAH, while the seedling size did not change significantly. In tall and red fescue, after-ripening significantly improved the final germination up to 120 DAH, while the seedling size variables reached maximum values after 150 DAH. The obtained data can serve for the determination of proper storage duration management between harvest and sowing (autumn/spring) of the tested fescue species under agro-ecological conditions of south-eastern Europe.Additional key words: autumn and spring sowing, biomass, root length, seedling dormancy-breaking effect, shoot length. ResumenComunicación corta. Efecto del periodo de post-maduración sobre la germinación de semillas y crecimiento de plántulas en tres especies de festuca La post-maduración es un proceso enzimático y bioquímico complejo que resulta en la rotura de la latencia fisiológica poco profunda. El experimento se estableció para identificar el tiempo mínimo de almacenamiento después de la cosecha para la terminación de la post-maduración en festuca de prados (Festuca pratensis Huds.), festuca alta (Festuca arundinacea Schreb.) y festuca roja (Festuca rubra L.). Las semillas se almacenaron durante 0, 30, 60, 90, 120, 150, 180, 210 y 240 días después de la cosecha (DAH). Después de los períodos de almacenamiento, se analizó la germinación de las semillas y se midieron la longitud de la raíz primaria, la longitud del vástago y la biomasa de las plán-tulas. Las tres especies tuvieron 60-65% de germinación inmediatamente después de la cosecha, lo que indica un nivel medio de latencia de embriones. La post-maduración durante el almacenamiento mejoró la germinación final en las tres especies, con una intensidad decreciente. En F. pratensis la germinación final aumentó considerablemente hasta 150 DAH, mientras que el tamaño de plántulas no cambió significativamente. En F. arundinacea y F. rubra la postmaduración mejoró significativamente la germinación final hasta 120 DAH, mientras que el tamaño de las plántulas alcanzó valores máximos después de 150 DAH. Los datos obtenidos pueden servir para una gestión adecuada de la duración de almac...

The effect of defoliation and date of nitrogen application in the spring to seed crops of meadow fescue, S215 and S53, were compared in two harvest years, in drills spaced at 18 in. S215 tillers were generally more robust than S53 tillers, and S215 produced a higher number of fertile shoots as the result of a higher conversion rate of overwintering to fertile tillers. N applied early and absence of defoliation gave the highest ratio of seed heads to overwintering tillers. Seed-and straw-yields were depressed by April and May defoliations; May cutting had a particularly drastic effect on both varieties. S53 yields in all treatments were generally inferior to those of the hay variety, S215. Head lengths and spikelet numbers were higher and 1000-seed weight lower in S53 than in S2I5.
