Abstract

The germination requirements of fve plant species from Brassicaceae; Thlaspi papillosum Boiss.& Huet, Thlaspi lilacinum Boiss., Draba brunifolia ssp. olympica Sibth. ex DC., Aubrieta olympica Boiss., Iberisspruneri Jord., from alpine site on Uludağ Mountain, Turkey, were investigated. The effects of moist chilling (+4 °C)for 15 and 30 days, and gibberellic acid (GA3; 250, 500 and 1000 ppm), and combined GA3 and moist chillingtreatments were studied under darkness (20°C) and light (20/10 °C; 12/12 h, light/dark). T.papillosum seeds werefound as non dormant, but the other four Brassicaceae seeds were found to have physiological dormancy whichcan be broken by moist chilling and GA3 combinations. T. lilacinum and D. bruniifolia seeds, were resulted highestgermination percentage at 1000 ppm GA3 at darkness with 30 days of moist chilling and GA3 combinations. A.olympica seeds germinated best at 15 days moist chilling and GA3 combinations at darkness. I. spruneri seedgermination increased at 15 days moist chilling and GA3 combinations at both darkness and photoperiod conditions.Interactions among moist chilling and GA3 were signifcant in I. spruneri and A. olympica seeds, but signifcantonly at darkness in T. lilacinum, and non-signifcant in D. bruniifolia seeds. Thus, prolonged moist chilling of seedscombined by GA3 under photoperiod conditions required to change the dormant status in these species. Our resultssuggest that these fve Brassicaceae species, three of them are endemic, have different germination requirements toescape unfavorable habitat conditions.

Özet

Bu çalışmada Uludağ alpin bölgede yetişen Brassicaceae familyasına ait Thlaspi papillosum Boiss. & Huet,Thlaspi lilacinum Boiss., Draba brunifolia ssp. olympica Sibth. ex DC., Aubrieta olympica Boiss., Iberis spruneriJord. türlerinin çimlenme gereksinimleri araştırıldı. Karanlık (20°C) ve fotoperiyot (20/10 °C; 12/12 h, ışık/karanlık) koşullarında, nemli soğuklama (15 ve 30 gün, +4 °C) ve gibberellik asit (GA3; 250, 500 and 1000 ppm) ilenemli soğuklama ve GA3 kombinasyonlarının etkileri araştırıldı. T.papillosum tohumlarının dormant olmadığı fakatdiğer dört Brassicaceae türünün tohumlarının nemli soğuklama ve GA3 kombinasyonları ile kırılabilen fzyolojikdormansiye sahip oldukları tespit edildi. T. lilacinum ve D. bruniifolia türlerinde en yüksek çimlenme başarısıkaranlıkta ve 30 gün nemli soğuklama ile 1000 ppm GA3 kombinasyonlarında bulundu. A. olympica tohumları enyüksek karanlıkta ve 15 gün gün nemli soğuklama ile GA3 kombinasyonlarında çimlendi. I. spruneri çimlenmesikaranlık ve fotoperitotta 15 gün gün nemli soğuklama ile GA3 kombinasyonlarında arttı. I. spruneri ve A. olympicatürlerinde nemli soğuklama ve GA3 interaksiyonu anlamlı, T. lilacinum türünde sadece karanlıkta anlamlı ve D.bruniifolia türünde ise anlamsız bulundu. Sonuç olarak üçü endemik olan beş Brassicaceae türünde dormansininkırılması için daha uzun süre nemli soğuklamaya veya GA3kombinasyonlarına gerek duyulduğu, bu farklı çimlenmedavranışlarının türlerin uygun olmayan çevre koşullarından kaçınabilmek için gerekli olduğu belirlenmiştir.
