“…The adverse effects of high salinity are also exacerbated by any increase or decrease in temperature . Halophytes usually germinate when a certain combination of light (photoperiod), temperature and salinity occurs (Ahmed and Khan, 2010;Gul et al, 2013;. In accordance with these studies of other halophytes, we have observed that the higher the temperature and salinity of the medium, the lower the germination percentage of L. tabernense.…”

“…A feature of halophytes is their ability to germinate after being relieved from exposure to high salinity (Khan and Gul, 2006;Orlovsky et al, 2011). This ability, called recovery, can be modulated by temperature (Gul et al, 2013;Khan and Ungar, 1996).…”

“…After germination but before root development, seedlings could not establish. They can be withered due to root exposure to wave and current (Bird 1984;Choi 1993;Lee 2011;Gul et al 2013). Therefore, early seedling establishment rate due to outer physical influence may determine individual maintenance, distribution range, and coverage of halophytes.…”

Background: The objective of this study was to determine the relationship between soil environmental factors and halophyte distribution in the west coast of South Korea. Soils of our study sites were categorized into two groups: salt marsh and estuary marsh. Results: Salinity was higher in the salt marsh group than that in the estuary marsh group. However, total nitrogen, silt, and clay contents were higher in the estuary marsh group than those in the salt marsh group. Although altitude had a wider range in the salt marsh group, the mean altitude was higher in the estuary marsh group than that in the salt marsh group. Annual halophytes of seed propagation species were distributed parallel to the coast line on salt marsh. Higher coverage of vegetation was found in the area closer to the coast line. Plant density was higher near dead parental plants in estuary marsh, showing less difference in area that was more distant from the coast line. Conclusions: Results of canonical correspondence analysis (CCA) for vegetation distribution and sediment environmental factors and germination analysis in the coast line showed significant relationship with halophyte distribution. Therefore, they can be used as an indicator of coastal plant movement due to sea level rise.

“…Bitkiler tuz stresine tolerans derecelerine göre glikofitler ve halofitler olmak üzere temel olarak iki gruba ayrılmaktadır. Halofitler aşırı sıcaklık değerlerinin olduğu, su kullanılabilirliğinin sınır olduğu ve toprak tuzluluğunun diğer bitkilerin yaşamını sınırlayacak seviyede olduğu habitatlarda doğal olarak yayılış gösteren bitkilerdir (Gul et al 2013). Halofitlerin yaşam döngülerindeki en önemli basamak tohum çimlenmesidir (Ungar 1995).…”

ÖzetHalofit bitki türlerinde tohum çimlenmesi özellikle ışık, sıcaklık ve tuzluluk gibi çevresel faktörler tarafından kontrol edilmektedir. Halofit Salsola crassa'nın tohum çimlenmesi üzerine tuzluluk, sıcaklık ve ışık etkileşimlerine ilişkin herhangi bir literatür bulunmamaktadır. Bu nedenle, bu araştırmada S. crassa'nın tohum çimlenmesi üzerine 9 tuz konsantrasyonu (0, 100, 200, 300, 400, 500, 600, 700 ve 800 mM NaCl), 6 sabit sıcaklık (10, 15, 20, 25, 30 ve 35C) ve fotoperiyodun (12 sa ışık: 12 sa karanlık ve sürekli karanlık) etkileri araştırılmıştır. En yüksek çimlenme yüzdeleri (%98-99) distile suda, 20 ve 25C sıcaklık uygulamaları ve 12 saatlik fotoperiyotta elde edilmiştir. Tuz konsantrasyonundaki artış özellikle düşük ve yüksek sıcaklık uygulamalarında tohum çimlenmesinde belirgin bir azalışa neden olmuştur. Düşük (10 ve 15C) ve yüksek (35C) sıcaklık uygulamaları hem kontrol hem de tuz uygulamalarında tohum çimlenmesinde belirgin bir şekilde azalmaya neden olmuştur. Tüm sıcaklık uygulamalarında ve özellikle tuz uygulamalarında ışık ve karanlık uygulamaları arasında önemli farklılıklar bulunmuştur (P < 0.05). Bu sonuçlar, S. crassa'da çimlenme evresi stres toleransının ışık, sıcaklık ve tuzluluk etkileşimleri tarafından etkilendiğini göstermektedir. Bununla birlikte, 800 mM NaCl konsantrasyonunda çimlenebilme yeteneğinden dolayı S. crassa'nın tuza oldukça toleranslı bir tür olduğu ileri sürülebilir. Effects of Salinity, Temperature and Light on Seed Germination of Halophyte Salsola crassa Keywords Germination;Light; Temperature; Salsola crassa; Salinity AbstractGermination of halophyte plant species is controlled by several environmental factors, in particular light, temperature and salinity. There is no literature on the interactions of salinity, temperature and light on the seed germination of halophyte Salsola crassa. In this study, therefore, effects of 9 salt concentrations (0, 100, 200, 300, 400, 500, 600, 700 and 800 mM NaCl), 6 constant temperatures (10, 15, 20, 25, 30 and 35C) and photoperiod (12 h light: 21 h darkness and continuous darkness) on seed germination of S. crassa were investigated. The highest germination percentages (98-99%) were obtained in distilled water, at 20 and 25C temperature applications and 12 h photoperiod. An increase in salt concentration caused marked decrease in seed germination especially at low and high temperature treatments. Lower (10 and 15C) and higher (35C) temperature treatments caused marked inhibition in seed germination at both control and salt treatments. There were significant differences between the light and dark treatments in all temperature and salt treatments (P < 0.05). These results show that the stress tolerance of S. crassa at germination stage is affected by the interaction of light, temperature and salinity. However, it may be suggested that S. crassa is a highly salt tolerant species because of its ability to germinate in 800 mM NaCl concentration.
