Özet
Bu çalışma ülkemizde tuzluluk problemi olan tarım alanları için tuzlu koşullara adapte olabilecek uygun kinoa çeşitlerin belirlenmesi amacı ile 2019 yılında Hatay Mustafa Kemal Üniversitesi Ziraat Fakültesi Tarla Bitkileri Bölümü laboratuvarlarında yürütülmüş olup, çalışmada materyal olarak yabancı orjinli 5 adet kinoa çeşidinin tohumu kullanılmıştır. Araştırma tuz stresine karşı toleransı belirlemek amacıyla her bir petri kabına 50 adet tohum yerleştirilerek yapılmıştır. Deneme, 4 tekkerrür olarak tesadüf parselleri deneme deseninde faktöriyel düzende 0, 100, 200, 300 ve 400 mM NaCl konsantrasyonları kullanılarak çimlenme kabininde yürütülmüştür. Araştırmada farklı tuz konsantrasyon seviyelerinde tohumların çimlenme oranları, çimlenme indeksi, ortalama çimlenme süresi, radikula uzunluğu, plumula uzunluğu ve yaş bitki ağırlığı değerleri incelenmiştir. Araştırmada kullandığımız çeşitler, tuz stresine bağlı olarak farklı tepki göstermiştir. Tuz yoğunluğu artıkca, çimlenme oranı, çimlenme indeksi radikula uzunluğu, plumula uzunluğu ve yaş bitki ağırlığı azalırken, ortalama çimlenme süresi uzamıştır. Araştırma neticesinde 400 mM gibi yüksek bir tuz konsantrasyonu seviyesinde bile çimlenebilen ve gelişebilen kinoa çeşitleri olduğu ve kinoa'nın ülkemizde tuzluluk problemi olan topraklarda dahi tarımı yapılabilecek bir bitki olduğu söylenebilir.
This study was carried out in the laboratories of Hatay Mustafa Kemal University, Faculty of Agriculture, Department of Field Crops in 2019 in order to determine suitable quinoa cultivars that can be adapted to salty conditions for the agricultural areas with salinity problems in our country and seeds of 5 quinoa cultivars from foreign origin were used as plant material. In order to determine the tolerance to salt stress, 50 seeds were placed in each petri dishes. The research was conducted in a germination cabinet with 4 replications according to the factorial arrangement in randomized plot design. In this research, germination rate (GR), germination index (GI), mean germination time (MGT), radicle length (RL) and plumula length (PL) and fresh seedling weight (FSW) values of different salt concentration levels were examined. The used cultivars in this research showed different reactions due to salt stress. As the salt concentration increased, germination rate, germination index, radicle length, plumule length and fresh plant weight decreased while the mean germination time was prolonged. As a result of the research, it was found that there were cultivars of quinoa that can germinate and develop even at a high salt concentration such as 400 mM and that quinoa was a plant that can be cultivated even in soils with salinity problems in our country.
