“…However, this reduction was significant in the sensitive genotype (Bn-16) in different drought levels compared to the tolerant genotype (Bn-150). In a previous study (Rosales et al, 2012;Li et al, 2013;Mansori et al, 2015;Kusvuran, 2015), the investigators showed that the MDA levels increased, especially in the susceptible phenotypes, depending on drought stress, and this increase was related to ROS formation. These results may be imputed to varieties in their genotypic ability to scavenge ROS and/ or to be protected against their oxidative properties.…”

The present study investigated different levels (S1: 100% of field capacity-Control S2: 50% of field capacity-moderate stress; S3: 0% of field capacity-severe stress) of drought stress on oxidative damages and variations in antioxidants in the two bean varieties Bn-16 (drought-sensitive), to elucidate the antioxidative protective mechanism governing differential drought tolerance. The shoot fresh weight, shoot height, leaf number and area, RWC were reduced with different level of drought stress. However this reduction clearly occurred in Bn-16 (sensitive). Antioxidative enzyme activities, such as superoxide dismutase, catalase, ascorbate peroxidase and glutation reductase, had a greater increase in tolerant genotypes (Bn-150) than in sensitive ones (Bn-16). The level of lipid peroxidation was measured by estimating malondialdehyde content. Lipid peroxidation increased with increasing drought conditions in all genotypes, although Bn-150 was the least affected when compared with the other genotype. Total phenolic and flavonoid content increased in bean genotypes under S2 and S3 conditions. The highest total phenolic and flavonoid contents were attained in Bn-150 subjected to S3 treatment. These results indicated that an antioxidant defence system, osmolytes (such as proline), and secondary metabolites play important roles in common bean (Phaseolus vulgaris L) during drought stress and recovery.

“…Many other researchers have emphasized that studies on different plants germination rates in salt stress are reduced by the increase in salt concentration (Day et al, 2008;Carpici et al, 2009;Akhtar and Hussain, 2009;Dai et al, 2009;Çacan and Kokten, 2014). Some other researchers also reported that germination index, mean germination time, radicle length and plumula length were decreased as the salt concentrations increased (Duan et al, 2004;Carpici et al, 2009;Kusvuran, 2015;Onal-Aşçı and Uney, 2016). Our results confirmed similar results to those outlined in previous studies, but the response of the cultivars, the extent to salinity tolerance of cultivars the salt concentration was different.…”

This research was carried out in the Mustafa Kemal University, Faculty of Agriculture, Department of Field Crops. It was used two Hungarian vetch cultivars (Altinova-2002 and Anadolu Pembesi-2002) and five salt concentrations (unsalted/0, 50 mM, 100 mM, 150 mM, 200 mM) as treatment. In this experiment, it was estimated germination rate (%), germination index and mean germination time (day) by using germination parameters and was also measured root and shoot length (mm) and seedling fresh weight (g). Salt concentrations negatively affected evaluated features for both cultivars in the final of this research. As the salt concentrations increased, all investigated properties except mean germination time were observed to decrease. In terms of germination rate, germination index, root and shoot length and seedling fresh weight between cultivars, Altionva-2002 cultivar gave higher value than Anadolu Pembesi-2002 cultivar. When we examined Cultivar x dose interactions, all properties were most affected adverse in the Anadolu Pembesi x 200 mM interaction This research clearly showed that the cultivation of Hungarian vetches of Anadolu Pembesi and Altınova-2002 will be affected in the soil that has been exposed to the problem of salinity.

“…Artan tuz yoğunluğu ile birlikte ortamın osmotik basıncı da arttığından tohumların su alıp çimlenmesi zorlaşmakta ve ortalama çimlenme süresi uzamaktadır (Steppuhn ve ark., 2001;Duan ve ark., 2004). Nitekim, artan tuz yoğunluklarının çimlenme oranını azalttığı birçok araştırıcı tarafından da tespit edilmiştir (Kaya ve İpek, 2003;Öz ve Karasu, 2007;Dumlupınar, 2005;Day ve ark., 2008;Kusvuran, 2015 Table 3.

Bu çalışma, Orta Karadeniz Bölgesinden toplanmış 85 adet Bituminaria bituminosa (Bitbit) genotipinin tuzluluğa dayanıklılık düzeylerinin belirlenmesi amacıyla, 2017 yılında Ondokuz Mayıs Üniversitesi, Ziraat Fakültesi Laboratuvar ve Seralarında yürütülmüştür. İki aşamalı olarak planlanan çalışmada, ilk aşamada 85 genotipe ait tohumlar sert tohum kabuğu giderildikten sonra farklı NaCl yoğunluklarında (0, 25, 50, 75 ve 100 mM) çimlendirilmiştir. Tuz yoğunluğu arttıkça çimlenme oranı, kökçük ve sürgün uzunluğu ve ağırlıkları azalmıştır. Yüksek dozlarda bazı genotiplerde hiç çimlenme olmamıştır. İkinci aşamada ise en iyi sonuç veren 10 genotip seçilmiş ve bu 10 genotiple serada fide aşamasında aynı tuz yoğunluğu içeren çözeltiler kullanılarak çalışılmıştır. Sera çalışmalarında, yüksek NaCl yoğunluğuyla beraber topraktaki tuzluluk artmış, belirli bir süreden sonra 75 ve 100 mM çözelti uygulanan bitkiler tamamen ölmüştür. Artan tuz yoğunlukları ile birlikte fidelerde bitki boyu, yaprak sayısı, bitki kök ve gövde ağırlığı azalmıştır. Yine tuz yoğunluğu arttıkça yapraklardaki klorofil a, klorofil b ve karotenoid miktarı azalırken, lipit peroksidasyonu ve prolin miktarının arttığı tespit edilmiştir. Determination of Salinity Tolerance Levels of Tedera (Bituminaria bituminosa L.) Genotypes Anahtar Sözcükler: Bituminaria bituminosa karotenoid klorofil prolin tuzluluk ABSTRACT This study was carried out to determine salinity resistance level of 85 Bitbit genotypes collected from Central Black Sea Region of Turkey, in OMU greenhouses and laboratories in 2017. The study was conducted in two steps. In the first step scarified seed of 85 genotypes were germinated in different NaCl concentrations (0, 25, 50, 75 and 100 mM). As salt concentration increase germination ratio, length and weight of radicle and pedicel decreased. There was no germination for some genotypes in higher doses. In the second step, the best 10 genotypes selected and same salt concentrations applied to seedlings of those genotypes in greenhouse. Soil salinity increased with increasing NaCl concentration and, all plants in 75 and 100 mM NaCl treatments were failed after application of saline water for a while. With increasing salt concentration plant height, leaf number, root and stem weight of the plants decreased. As salt concentration increase, amount of chlorophyll a, chlorophyll b and carotenoid of the leaves decreased while lipid peroxidation and prolin level increase.
