<b>Influences of presowing treatments on the germination and emergence of fig seeds (<i>Ficus carica</i> L.)</b> - doi: 10.4025/actasciagron.v34i3.13392

Resumo

Seed germination of fig seeds is important for obtain seedlings with high variability in breeding studies, and for producing mosaic virus-free seedlings. This experiment was carried out to evaluated the effects of several treatments (priming with water for 24h, GA₃ at 500 and 1000 ppm for 24h, 3% KNO₃ for 24h, and stratification at 4°C for 7, 14 and 21 days) on seed germination and emergence of ‘Bursa Siyahı’ and ‘Sarılop’ fig cultivars. The application of GA₃ increased the germination and emergence of these fig seeds. The highest percentages of germination and emergence were obtained with GA₃ at 500 or 1000 ppm for both cultivars. The seed germination and emergence of the cultivar ‘Bursa Siyahı’ were higher than observed with the ‘Sarılop’. The application of GA₃ at 500 ppm or 1000 ppm reduced the time to germination and emergence from the seeds of both cultivars. In summary, the GA₃ treatments showed efficacy to overcome the dormancy of these fig seeds.
