It is known that salinity is one of the most important abiotic stress factors reducing productivity in agriculture. High salt concentration has a negative effect on seed germination and seedling formation. Magnetic field treatment can be considered as an environmentally friendly, innovative and inexpensive method to increase tolerance to stress, as a productivity-enhancing factor in agriculture. In this study, germination rate, germination strength, shoot and root length, fresh and dry weights, chlorophyll a, b and total chlorophyll content and ion leakage values of three different barley varieties under the influence of 150 mT constant magnetic field at different time intervals were determined. In light of the results, it was determined that although it varies according to the barley varieties, it has a significant positive effect on the germination rate and strength depending on the duration of the applied magnetic field. This study revealed that the magnetic field seed treatment has different effects according to the treatment time and the severity of the salt stress.

Salinity is a critical environmental factor that adversely affects crop growth and productivity. This study aimed to evaluate the effects of gibberellic acid (GA3) on germination, shoot length, root length, and biomass of two wheat cultivars (Demirhan and Fazılbey) under varying levels of salt stress (0, 5, and 10 dS/m NaCl). GA3 was applied at concentrations of 100 and 200 ppm to assess its potential in alleviating the adverse effects of salinity. The results revealed that GA3 significantly improved germination percentage, shoot length, and root length in both cultivars, with the Demirhan cultivar showing more pronounced responses under higher salt stress. A biplot analysis highlighted the interaction between GA3 treatment, salinity levels, and cultivar performance, confirming the positive role of GA3 in mitigating the detrimental effects of salinity. These findings suggest that GA3 can be an effective strategy for enhancing wheat growth in saline soils. Further studies are recommended to optimize GA3 concentrations and evaluate its long-term effects under field conditions.

This research was carried out to determine the response of some durum wheat cultivars to salt stress during the germination stage. In the study, in which 11 durum wheat varieties, which are widely produced in different regions of Turkey, were used, 3 g l-1 and 6 g l-1 doses of NaCl were applied in addition to the distilled water application. In the research, germination rate, germination power, root length, shoot length, fresh and dry weight properties were investigated. The study was carried out according to the Factorial Experiment Design in Random Plots under laboratory conditions. Statistically significant differences were found between cultivars and salt doses, except for fresh and dry weight, in terms of all traits examined. Additionally, variety x salt dose interactions were found as important in terms of other characteristics except for dry weight. The highest germination rate, germination power and dry weight were determined in Altıntaş-95, highest root length in Eminbey and highest fresh weight Yelken varieties. Except for and dry weight, other properties were significantly reduced with increasing salt dose.

Tuz stresi altında makarnalık buğday çeşitlerinin çimlenme ve erken fide dönemini değerlendirmek amacıyla, farklı tuz (NaCI) konsantrasyonları (0, 3 ve 6 g L-1) ve 10 adet makarnalık buğday çeşidi (Altıntaş-95, Ç-1252, Dumlupınar, Eminbey, Kunduru-1149, Kızıltan-91, Mirzabey-2000, Soylu, Svevo, Türköz) ile bu araştırma yürütülmüştür. Çalışmada çimlenme ve fide gelişiminin bazı indeksleri hesaplanmış ve analiz edilmiştir. Tuz stresi çimlenme kapasitesini (ÇK) ve çimlenme indeksini (Çİ), önemli ölçüde azaltırken, stres indeksini (Sİ) artırmıştır. Fide büyümesi ve başlangıç canlılığı (İC) da tuz etkisiyle önemli ölçüde engellenmiştir. İncelenen özellikler bakımından, çeşitler arasında farklılıklar ortaya çıkmış olup Altıntaş-95 artan tuz dozlarından en az etkilenen çeşit olurken, Kızıltan-91 ve Svevo en çok etkilenen çeşitler olmuştur. Çeşitlere bağlı olarak, tuz stresi çimlenme kapasitesini azaltırken fide gelişimini de etkilemiştir. Araştırma sonucu elde edilen bulgulara göre ortamda bulunan tuzun, osmotik etkisi nedeniyle bitkilerin su alımını engelleyerek çimlenmeyi geciktirdiği ve yüksek tuz seviyesinin (6 g L-1 NaCl) bitkilerin hücresel yapılarına zarar verdiği bu nedenle de çimlenme ve fide gelişiminin etkilendiği gözlemlenmiştir. Bu bağlamda da buğday çeşitleri arasında belirgin bir ayrım yapma imkânı sağlayan ilk canlılık ve stres indeksinin, tuzluluğa karşı toleranslı bitki genotiplerini belirlemek için faydalı özellikler olduğu söylenebilir.

This study was carried out to determine the quality characteristics of some durum wheat varieties grown in different regions of Turkey under Konya ecological conditions. Altıntaş-95, Burgos, Ç-1252, Dumlupınar, Eminbey, Imren, Kızıltan-91, Kunduru-1149, Leonardo, Levent, Kümbet-2000, Mimmo, Mirzabey-2000, Sırçalı, Soylu, Svevo, Traubadur, Türköz, Vehbibey, Yelken-2000 varieties were used as plant material. In the research, the field trial was established in a randomized block design with three replications. Within the scope of the research; hectoliter weight, glassiness, semolina color and protein characteristics were examined. In the study, significant differences were found between the varieties in terms of hectoliter weight and protein ratio, while semolina color and glassiness were found insignificant. The highest hectoliter weight was found in the Yelken-2000 variety and the highest protein ratio was found in the Burgos variety.

Durum wheat (Triticum durum L.) productivity is strongly limited by salinity stress, particularly during early growth stages, due to disruptions in growth,
