Deniz yosunu özü uygulamalarının tuzlu koşullarda pırasada tohum çimlenmesi üzerine etkisi

Bu araştırma, deniz yosunu özü uygulamalarının, tuzlu koşullarda pırasada tohum çimlenmesi üzerine etkisini belirlemek amacıyla yürütülmüştür. Kalem ve İnegöl 92 çeşitlerine ait tohumlar, 1:250, 1:500, 1:1000 konsantrasyonlarında deniz yosunu özü ve saf suda 24 saat süreyle bekletilmişlerdir. Daha sonra tohumlar, saf su ile yıkanıp 20°C'de beş faklı tuz konsantrasyonunda (0, 50, 75, 100 ve 125 mM) 14 gün süre ile çimlendirilmişlerdir. Araştırmada, toplam çimlenme oram ve çimlenme hızının ifadesi olarak Çimlenme Oran İndeksi (ÇOİ) tespit edilmiştir. Deneme sonunda, suda bekletme ve deniz yosunu özü uygulamalarının pırasa tohumlarında gerek çimlenme oranını gerekse ÇOİ'ni kontrole göre önemli ölçüde artırdığı saptanmıştır.

The effect of seaweed extract treatments on germination of leek seeds under salinity

This study was conducted to determine the effect of seaweed extract treatments on seed germination of leek under salt stress. The seeds of İnegöl 92 and Kalem cultivars were maintained in 1:250, 1:500 and 1:1000 concentrations of seaweed extract, as well as in H2O for 24 hours. Then, the seeds were put in the petri dishes containing five different NaCl concentrations (0, 50, 75,100 and 125 mM). Petri dishes were placed randomly in an incubator at 20°C for 14 days. In the study, total germination percentage and germination rate index were determined. According to the results, seaweed extract and H2O treatments increased significantly both germination percentage and gemnination rate index compared with control.
