Özet

The present study was carried out at two locations over the experimental fields of Field Crops Department of Ankara University Agricultural Faculty and Eskisehir Transitional Zone Agricultural Research Institute. Two different hybrid sorghum cultivars (Sugar Grazer II and Digestivo) were used as the experimental material. Putrescine, jasmonic acid, kinetin, KNO3, salicylic acid and control treatments were applied to selected genotypes. The lowest number of days (the earliest) to 50% emergence (9.75 days) was obtained from KNO3-primed aged Sugar Grazer II seeds at Eskisehir location. The greatest panicle seed yield per plant (78.21 g) was obtained from KNO3-primed unaged Digestivo seeds at Eskisehir location. The greatest seed yield per decare (694.91 kg/da) was obtained from salicylic acid-primed aged Sugar Grazer II seeds at Eskisehir location. The greatest protein ratio (15.07%) was obtained from KNO3-primed unaged Digestivo seeds at Ankara location. Priming with salicylic acid, KNO3 and jasmonic acid yielded the best outcomes for quality traits of sorghum hybrids.
