Özet

In this research, the effects some pretreatments (stratification, soaking, cracking and gibberellic acid) and combinations of treatments on the germination ratio of jujube (Ziziphus spp) seeds were investigated. The study was carried out between 2016 and 2017 in the laboratory and high tunnel of Department of Horticulture in the Faculty of Agriculture, Kirsehir Ahi Evran University, Turkey. Total of 32 different pretreatments including the control treatment were used to break the dormancy of jujube seeds. The pretreatments were dual combinations of cracking, soaking in 12 and 24 hours, stratification in 30, 60 and 90 days and 12 hours soaking in 200 ppm and 400 ppm GA(3) solutions. The highest germination ratio (23.33%) was obtained with 200 ppm GA(3) treatment, while the lowest germination (0%) ratio was obtained by soaking in water for 12 hours and 30-day stratification treatments, respectively. In dual combination treatments, the highest germination ratio (58.33%) was found in 200 ppm GA(3) + cracking treatment, while the lowest germination ratio (0%) was obtained from 30 days stratification + soaking in water for 12 hours treatment.
