Özet: Bu çalışmada deniz yosunu özü ve gibberellik asit (GA3) priming uygulamaları ile vermikompost uygulamasının yabani zeytin tohumlarında bitki çıkış oranı ve çöğür gelişimine etkisinin belirlenmesi amaçlanmıştır. Tohumlar 12 Şubat 2021 tarihinde ekilmiş, ilk bitki çıkışları 15 Aralık 2021 tarihinde başlamıştır. Bitki çıkış oranı, % 34.67 (20 g l-1 deniz yosunu özü) – % 62.67 (% 20 vermikompost) arasında tespit edilmiştir. Çöğür gelişim parametrelerinde uygulamalar arasındaki fark önemli olup, sürgün sayısı dışındaki diğer parametrelerde en düşük değerler kontrol bitkilerinde en yüksek ise % 40 vermikompost uygulamasında tespit edilmiştir. Zeytin fidanı üretim sürecinde, başta vermikompost olmak üzere, deniz yosunu özü ve GA3 kullanımının yararlı olabileceği sonucuna varılmıştır.

In this study, it was aimed to determine the effects of seaweed extract and gibberellic acid (GA3) priming applications and vermicompost on plant emergence and seedling growth of wild olive seeds. Seeds were sown on February 12, 2021, the first plant emergence started on December 15, 2021. Plant emergence rate was determined between 34.67 % (20 g l-1 seaweed extract) – 62.67 % (20 % vermicompost). The difference between the applications in seedling growth parameters is significant, and the lowest values in other parameters except the number of shoots were determined in the control plants and the highest in 40 % vermicompost application. Accordingly, the average per plant determined in the range; plant height 6.54 cm – 20.84 cm, root collar diameter 2.14 mm – 3.04 mm, root length 13.75 cm – 21.75 cm, shoot fresh weight 0.66 g – 3.07 g, shoot dry weight 0.24 g – 1.06 g, root fresh weight 0.20 g – 1.15 g, root dry weight 0.07 g – 0.31 g, number of leaves 14.90 – 38.49, shoot number 1.14 (250 ppm GA3) – 2.17 (40 % vermicompost) were determined in the range. It was concluded that the use of seaweed extract and GA3, especially vermicompost, can be beneficial in the olive sapling production process.
