Abstract

The effects of kinetin, benzyladenine (BA), and gibberellic acid (GA 3 ) on abscisic acid (ABA) inhibition of seed germination and seedling growth of red pine (Pinus brutia Ten.) and arbor vitae (Thuja orientalis L.) were studied. For this purpose, the seeds of these two species were germinated in Petri dishes containing ABA and the mixtures of its with kinetin, BA, and GA 3 alone or in combination at 20ºC for 12 or 15 days for arbor vitae and red pine, respectively. The inhibitory effect of ABA on percentages of the seed germination and hypocotyl emergence, the time course of the germination, and the radicle and hypocotyl elongation of the seedlings was overcome very successfully by GA 3 alone in comparison with kinetin, BA, and the combinations of these two cy-tokinins alne with GA 3 . Kinetin or BA alone did not mostly fail to overcome ABA inhibition on the mentioned parameters. There were the cases that also the combinations of these cytokinins with GA 3 were successful or not. GA 3 alone was the most successful hormone at all the cases in general.

Özet

Bu araştırmada kızılçam (Pinus brutia Ten.) ve mazı (Thuja orientalis L.) tohumlarının çimlenmesi ve fide büyümesindeki absisik asit (ABA) engellemesi üzerine kinetin, benziladenin (BA) ve gibberellik asitin (GA3) etkileri incelendi. Bu amaçla bu iki türün tohumları, ABA ve bu hormonun kinetin, BA ve GA3 ile ayrı ayrı ve kombinasyon halindeki karışımlarını içeren petrilerde 20ºC’de 12 (mazı) veya 15 gün (çam) boyunca çimlendirildi. Tohum çimlenmesi ve hipokotil çıkış yüzdeleri, zamana bağlı çimlenme ile fidelerin radikula ve hipokotil uzaması üzerindeki ABA’nın engelleyici etkisi kinetin, BA ve bu iki sitokininin GA3 ile ayrı ayrı yaptıkları kombinasyonlara nazaran tek başına GA3 ile çok başarılı bir şekilde yenildi. Tek başına kinetin veya BA, adı geçen parametreler üzerindeki ABA engellemesini yenmeyi çoğunlukla başaramadı. Bu sitokininlerin GA3 ile kombinasyonlarının ise başarılı veya başarısız olduğu durumlar vardı. Tek başına GA3, genellikle her durumda en başarılı hormondu.
