“…Different responses of cultivars to salinity levels may be resulted from the differences in their genetic structures. The primary reason for negative influences of high salt concentrations in germination period is the inhibition of required water intake of seeds for germination (MANSOUR, 1994).…”

“…In salinity researches, germination (COSKUN et al, 2016) and shoot stage (VAN HOORN et al, 2001) are commonly considered while investigating plant response to salinity. The problems experienced in germination period under high salt concentrations were mainly because of hindered water intake of seeds (MANSOUR 1994). Also under salt stress, excessive Na accumulation in plants hinders K uptake (SIEGEL et al, 1980) and high Cl concentrations hinder NO3 uptake of plants (INAL et al, 1995) and both ions destroy plant ion balance.…”

This study was conducted to investigate the effects of different irrigation water salinity level on chromosomes and shoots of wheat with three different ploidy level (diploid, tetraploid and hexaploid). Greenhouse experiment revealed that irrigation water salinity level had significant effects on shoot dry weight, root dry weight, shoot length and root length (P<0.05). The effects of ploidy level and cultivar shoot dry weight and root dry weight were also found to be significant (P<0.05), but the effects on shoot length and root length were not significant (P>0.05). Negative effects of salinity on shoot and root were started at 8 dS m-1. Also hexaploid wheat was more tolerant then tetraploid and diploid wheat to salinity. It was not determined that possible effects of irrigation water salinity to structure of chromosomes with current equipment and methods. Cell divisions were normal, but decreasing cell division rates were observed with increasing irrigation water salinity levels.

“…Çimlenme oranının azalmasına yüksek tuz konsantrasyonunun su alımını engellemesi, tuzun toksik etki yapması ve çimlenme sırasında gerekli olan enzimlerin tuz stresinden dolayı aktif hale gelememesinin neden olduğu bildirilmektedir (Mansour, 1994;Essa, 2002;Sadeghian ve Yavari, 2004).…”

ÖZET Bu çalışmada; farklı sulama suyu tuzluluk düzeylerinin(0.38 (kontrol), 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 dS m -1 ) keten tohumlarının çimlenme hızı, çimlenme oranı, sürgün ve kök uzunlukları, sürgün yaş ve kuru ağırlığı, kök yaş ve kuru ağırlığı üzerine etkileri incelenmiştir. Araştırma sonuçlarından tohum çimlenme hızı, çimlenme oranı ve tuz toleransı indeksi değerlerinin sırasıyla % 52.2-76.0, % 66.5-97.0, %39.0-112.0 arasında değiştiği tespit edilmiştir. Tuzluluğu 2 dS m -1 olan çimlenme ortamında, incelenen tüm gelişim parametrelerinin en iyi değere ulaştığı ve tuzluluk düzeyinin 2 dS m -1 "den yüksek olduğu koşullarda ise tohum çimlenmesi ve erken fide gelişim parametrelerinin olumsuz yönde etkilendiği belirlenmiştir. Bununla birlikte, araştırma sonucu incelenen bütün parametreler dikkate alındığında; kurak ve yarı kurak bölgelerde, 2 dS m -1 tuzluluk düzeyine kadar olan suların, ketenin çimlenme ve erken fide gelişim dönemlerinde kullanılabileceği tespit edilmiştir.The effects of different irrigation water salinity levels on germination and early seedling development of flax (Linum usitatissimum L.) Anahtar Sözcükler: Tohum çimlenmesi Tuzlu sulama suyu Tuz stresi Yağlı tohum ABSTRACT In the the present study, the effects of different irrigation water salinity levels (0.38 (control), 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 dS m -1 ) on germination speed, germination rate, shoot and root lengths, shoot wet and dry weights, root wet and dry weights of flax seed were investigated. The germination speed, germination rate and salt tolerance index changed between 52.2-76.0 %, 66.5-97.0 % and 39.0-112.0 %, respectively. All the development parameters attained the best values in germination medium with 2 dS m -1 salinity. However, the salinity levels higher than 2 dSm-1 had negative effect on seed germination and early seedling development parameters. When all of the parameters were taken into consideration it was noted that irrigation water with up to 2 dS m-1 salinity can be used for flax seed germination and early seedling development in arid and semi-arid regions.

“…In studies on salinity, germination and seedling development are typically examined in determining how crop genotypes respond to salt (Ghoulam and Fares, 2001; Kara and Uysal, 2010). The top reason why seeds in overly salty soils face adversity during germination is the stunted intake of water through the seed coat (Coons et al, 1990;Mansour, 1994). Beyond that, deterioration in the ion balance in plants grown in saline soils damages their physiological functions, including their capacity for photosynthesis and respiration (Levitt, 1980;Aydınşakir et al, 2012).…”

The germination and seedling characteristics of six forage pea cultivars were investigated under different levels of salinity (0, 5, 10, 15, and 20 dS/m) and drought (0,-2, and-4 bar) stresses. All characteristics of germination and seedling growth varied by cultivar, salinity and drought levels, and their interactions. With high seedling lengths overall, Özkaynak, Ulubatlı, and Töre cultivars demonstrated low reduction rates in seedling length when salinity reached 15 dS/m, whereas the Taşkent cultivar's reduction rate increased considerably at that level of salinity, as did Ürünlü and Gölyazı cultivars. Meanwhile, the Gölyazı cultivar had high fresh and dry weights, despite high reduction rates in fresh weight, similar to the Taşkent cultivar. Though the Ulubatlı cultivar had the shortest seedlings, they exhibited a low reduction rate in seedling length at-2 bar of drought stress, as did Töre and Özkaynak cultivars. At that level of drought stress, those cultivars also indicated low reduction rates in fresh weight. Altogether, the Töre cultivar best tolerated salinity and drought conditions, the Özkaynak cultivar showed promise as well, whereas Taşkent and Gölyazı cultivars were the most sensitive to the conditions.
