Özet:

 Drought is an important environmental stress that causes significant yield losses in agricultural production. Besides the negative effects of drought stress on the growth and development of plants, it also has an important effect on the quality of the products. In the study, the drought resistance of Triticum spelta genotypes, which is a hexaploid wild wheat species, was tested. The study was carried out in greenhouse conditions with 18 different T. Spelta genotypes, in a randomized plot design with 4 replications. The study was conducted under three different drought treatments TK35, TK45 and TK70-control. In plants harvested in the grain maturity period; plant yield, grain yield, 1000 grain yield, harvest index, stress tolerance index and grain N, P and K concentrations were determined. Compared to the control application TK70 of all T. Spelta genotypes tested under three different drought stresses, statistically significant decreases were observed in the dry matter yields, grain yields and 1000 grain yields of the genotypes p0.01 and p0.05 in TK35 and TK45 applications. According to the control conditions, plant yield, grain yield, harvest index and stress tolerance index values were higher in SP434, SP521 and SP2 genotypes in TK35 and TK45 applications. It was found that the grain N, P and K concentrations of the genotypes increased significantly p0.01, p0.05 with the increase in the degree of drought. According to the results obtained, it was revealed that the responses of different T. Spelta genotypes to drought were different, and among the genotypes, the genotypes SP434, SP521 and SP2 were more resistant to drought than other genotypes.

 Kuraklık, tarımsal üretimde önemli verim kayıplarına neden olan önemli bir çevresel strestir. Kuraklık stresi bitkilerin büyüme ve gelişimi üzerine olan olumsuz etkilerinin yanında ürünlerin kalitesi üzerinde de önemli etki yapar. Çalışmada hekzaploid yabani buğday türü olan Triticum spelta genotiplerinin kuraklığa karşı dayanıklılıkları test edilmiştir. 18 farklı T. spelta genotipi ile sera koşullarında yürütülen çalışma tesadüf parselleri deneme desenine göre 4er tekerrürlü olarak gerçekleştirilmiştir. Çalışma 3 farklı su stresi uygulaması TK70-kontrol, TK35, TK45 altında yapılmıştır. Tane olgunluk döneminde bitkiler hasat edilmiş ve bitkilerde kuru madde verimi, tane verimi, 1000 tane ağırlığı, hasat indeks ile stres tolerans indeks değerleri ve tanede N, P ve K konsantrasyonları belirlenmiştir. Sonuç olarak, farklı su stresi uygulamaları altındaki T. spelta genotiplerinin kontrol uygulamasına TK70 göre TK35 ve TK45 uygulamalarında kuru madde verimleri, tane verimleri ve 1000 tane ağırlıklarında istat iksel olarak p0.05 önemli oranlarda azalmaların olduğu görülmüştür. Kontrol koşullarına göre TK35 ve TK45 uygulamalarında kuru madde verimi, tane verimi, hasat indeks ile stres tolerans indeksi değerleri bakımından SP434, SP521 ve SP2 numaralı T. spelta genotiplerinde daha fazla çıkmıştır. Kuraklık derecesinin artışı ile paralel şekilde genotiplerin tane N, P ve K konsantrasyonlarının da önemli oranda p0.05 arttığı ortaya çıkmıştır. Elde edilen sonuçlara göre farklı T. spelta genotiplerinin kuraklığa karşı verdiği tepkilerin farklı olduğu ve SP434, SP521 ve SP2 numaralı genotiplerin diğer genotiplere göre kuraklığa karşı daha toleranslı olduğu görülmüştür.
