Abstract

This study was conducted to evaluate the effect of NaCl and peg-induced osmotic stress on thegermination and early seedling growth of wild mustard (Sinapis arvensis L.) in 2016. The seeds of mustard used in this studywere obtained from plants growing under wild conditions in the Konya, Turkey. Trials were carried out to study the effects ofosmotic potential of polyethylene glycol (PEG-6000) solutions at seven levels (0, -2, -4, -6, -8, -10 and -12 bars) and saltconcentrations at eight levels (0, 2, 5, 10, 15, 20, 25, 30 and 35 dSm-1) on seedling growth of wild mustard. Under PEG and saltstress the radicula length (cm), plumula length (cm), seedling fresh weight (mg), seedling dry weight (mg), final germinationpercentage (%), germination index (%) and seedling vigor index (%) were measured in the study. Final germination percentageand seedling growth parameters decreased by concentration of -4 to -10 bar for PEG stress; final germination percentagedecreased by 10 dSm-1 (-4.4 bar) and seedling growth parameters decreased by 5 dSm-1 (-2.2 bar) for NaCl stress. Both NaCland PEG treatments decreased final germination percentage and seedling growth properties in wild mustard, but the effects ofNaCl compared to PEG were less on germination. Seed germination was completely inhibited at -12 bar for PEG stress, 35 dSm1 (-15.6 bar) for NaCl stress.

Özet

Bu çalışma farklı NaCl ve PEG uygulamalarının yabani hardalın (Sinapis arvensis L.) çimlenme ve erken vejetatif gelişme üzerine etkisini belirlemek amacıyla 2016 yılında yürütüldü. Çalışmada kullanılan yabani hardal tohumları Konya’da yabani koşullarda yetişen bitkilerden alınmıştır. Denemede yedi farklı polietilen glikol (PEG-6000) solüsyonu (0, -2, -4, -6, -8, - 10 ve -12 bar) ve dokuz farklı NaCI solüsyonu (0, 2, 5, 10, 15, 20, 25, 30 ve 35 dSm-1) kullanılmıştır. Farklı PEG ve NaCl uygulamalarında kök uzunluğu (cm), sürgün uzunluğu (cm), fide yaş ağırlığı (mg), fide kuru ağırlığı (mg), final çimlenme oranı (%), çimlenme indeksi (%) ve fide canlılık indeksi ölçümleri yapılmıştır. Çalışma sonucunda, final çimlenme oranının ve fide büyüme parametrelerinin artan PEG konsantrasyonlarına (-4 / -10 bar) bağlı olarak azaldığı; final çimlenme oranının 10 dSm-1 (-4,4 bar)’den itibaren azalmaya başladığı ve fide büyüme parametrelerinin 5 dSm-1 (-2,2 bar)’den itibaren azalmaya başladığı belirlenmiştir. Ayrıca, NaCl ve PEG uygulamalarının çimlenme ve fide gelişimini düşürdüğü; fakat PEG’e kıyasla NaCl’ün etkisinin çimlenmede daha az olduğu; çimlenmenin -12 bar PEG ve 35 dSm-1 (-15,6 bar) NaCl dozlarında tamamen durduğu tespit edilmiştir.
