Abstract

The seed dormancy of Prangos ferulaceae (Apiaceae) has been studied with treatment the seeds by soaking, scarification, cold and warm stratification, alternating temperatures and GA3. Our results showed that the seeds dormancy can be broken by cold stratification at 5°C and 12°C which induced germination up to 35 and 40%, respectively. Alternating temperatures (15/6°C) promote germination only to 15%. Scarification, soaking, warm stratification and GA3 had no significant effects on seed germination. It has been found that light inhibits seed germination and the seeds have a negative photoblasticity. It has also been shown that cold temperatures promote the growth of the undeveloped embryo of the plant. After 10 weeks stratification of the seeds at 5°C, the embryo length increased 200%. In conclusion, it is obvious that, the seeds of P. ferulaceae have morphophysiologic dormancy.

Özet

Prangos ferulaceae (Apiaceae)'da tohum dormansisi; islatma, yaralama, soguk-sicak derecelendirmesi, degisken sicakliklar ve GA3 uygulamalari ile çalisilmistir. Sonuçlarimiz tohum dormansisinin, sirasiyla %35 ve 40'a kadar çimlenmeye yol açan 5°C ve 12°C'de soguk derecelendirmesi yoluyla kirilabilecegini göstermistir. Degisken sicakliklar (15/6°C) sadece %15'e kadar çimlenmeye neden olmaktadir. Yaralama, islatma, sicak derecelendirmesi, ve GA3 uygulamalarinin tohum çimlenmesi üzerine herhangi önemli bir etkisi yoktur. Isigin çimlenmeyi inhibe ettigi ve tohumlarin negatif fotoblastisitesinin oldugu bulunmustur. Ayrica, dusuk sicaklilarin bitkide gelismemis embriyo büyümesini tesvik ettigi gösterilmistir. Tohumlarin 5°C'de 10 haftalik derecelendirilmesinden sonra embriyo uzunlugu %200 artmistir. Sonuç olarak, P. ferulaceae tohumlarinin morfofizyolojik dormansisinin oldugu açiktir.
