“…Nesom & Pruski, had reduced SPAD readings at elevated salinity stress (Niu et al, 2007). Increasing salinity stress was also shown to decrease leaf SPAD readings in two cherry (Prunus cerasus L.) rootstocks (Sotiropoulos et al, 2006). In a study by , leaf SPAD readings decreased as salinity level increased from 1.6 to 6.0 dS • m -1 .…”

Earth-Kind® is a special designation given to select rose cultivars with superior stress tolerance (heat, drought, and pest tolerance) and outstanding landscape performance. The responses of Earth-Kind® roses to high salinity stress are unknown. A greenhouse study was conducted to evaluate 18 Earth-Kind® rose cultivars (Belinda’s Dream, Cecile Brunner, Climbing Pinkie, Ducher, Duchesse de Brabant, Else Poulsen, Georgetown Tea, La Marne, Madame Antoine Mari, Marie Daly, Monsieur Tillier, Mrs. Dudley Cross, Mutabilis, Perle d’Or, Reve d’Or, Sea Foam, Souvenir de St. Anne’s, and Spice) in College Station and 10 of the same 18 cultivars in El Paso in response to two salinity levels at electrical conductivity (EC) of 1.2 (control, nutrient solution) and 10.0 dS·m−1 (EC 10). In both locations, ‘Belinda’s Dream’ and ‘Climbing Pinkie’ in EC 10 had no or little reduction in shoot growth, flower number, and leaf SPAD readings. The net photosynthetic rate (Pn), stomatal conductance (gS), and transpiration (E) did not decrease in these two cultivars at EC 10 in El Paso. In College Station, ‘Mrs. Dudley Cross’, ‘Reve d’Or’, and ‘Sea Foam’ in EC 10 also had no or little reduction in shoot growth, flower number, and leaf SPAD readings. In both locations, ‘Cecile Brunner’ and ‘Else Poulsen’ in EC 10 had severe visual foliar salt damage, and they had the greatest reductions in shoot growth and flower number. In addition to these two cultivars, the lowest relative shoot dry weight (DW) and flower number was observed in ‘Madame Antoine Mari’, ‘Perle d’Or’, ‘Spice’, and ‘Souvenir de St. Anne’s’ in College Station. In summary, ‘Belinda’s Dream’, ‘Climbing Pinkie’, ‘ Mrs. Dudley Cross’, ‘Reve d’Or’, and ‘Sea Foam’ were the most salt-tolerant cultivars, whereas ‘Cecile Brunner’, ‘Else Poulsen’, ‘Madame Antoine Mari’, ‘Perle d’Or’, ‘Spice’, and ‘Souvenir de St. Anne’s’ were the least salt-tolerant among the cultivars investigated.

“…This is in agreement with our previous study in which leaf SPAD readings were reduced by elevated salinity of irrigation water in some of the herbaceous species (Niu et al, 2007). Although no relationships between chlorophyll concentrations and SPAD readings for these rose species have been previously established, measuring leaf SPAD readings have been shown to be an efficient method to rapidly and nondestructively quantify the initial or mild salt damage in tomato (Montesano and van Iersel, 2007) and cherry rootstocks (Sotiropoulos et al, 2006).…”

Salt-tolerant landscape plants are needed for arid and semiarid regions where the supply of quality water is limited and soil salinization often occurs. This study evaluated growth, chloride (Cl) and sodium (Na) uptake, relative chlorophyll content, and chlorophyll fluorescence of three rose rootstocks [Rosa ×fortuniana Lindl., R. multiflora Thunb., and R. odorata (Andr.) Sweet] irrigated with saline solutions at 1.6 (control), 3.0, 6.0, or 9.0 dS·m−1 electrical conductivity in a greenhouse. After 15 weeks, most plants in 9.0 dS·m−1 treatment died regardless of rootstock. Significant growth reduction was observed in all rootstocks at 6.0 dS·m−1 compared with the control and 3.0 dS·m−1, but the reduction in R. ×fortuniana was smaller than in the other two rootstocks. The visual scores of R. multiflora at 3.0 and 6.0 dS·m−1 were slightly lower than those of the other rootstocks. Rosa odorata had the highest shoot Na concentration followed by R. multiflora; however, R. multiflora had the highest root Na concentration followed by R. odorata. All rootstocks had higher Cl accumulation in all plant parts at elevated salinities, and no substantial differences in Cl concentrations in all plant parts existed among the rootstocks, except for leaf Cl concentration in R. multiflora, which was higher than those in the other two rootstocks. The elevated salinities of irrigation water reduced the relative chlorophyll concentration, measured as leaf SPAD readings, and maximal photochemical efficiency of photosystem II (PSII) and minimal fluorescence (Fo)/maximum fluorescence (Fv/Fm), but the largest reduction in Fv/Fm was only 2.4%. Based on growth and visual quality, R. ×fortuniana was relatively more salt-tolerant than the other two rootstocks and R. odorata was slightly more salt-tolerant than R. multiflora.

“…Tuz (NaCl) stresinde klorofil içeriğinin azalması, tuzluluğun bitkiler tarafından Mg ve Fe gibi iyonların alımını olumsuz etkilemesi, bunun sonucu olarak kloroplast oluşumunun ve klorofil biyosentezinin azalması şeklinde açıklanmaktadır (Neocleous & Vasilakakis 2007). Sotiropoulos et al (2006b), tuz uygulaması ile klorofil içeriğinin kiraz anaçlarında azaldığını ancak Gisela 5'in CAB 6P' ye göre daha fazla klorofil içerdiğini belirtmiştir. Tuz uygulaması ile bitkide klorofil içeriğinin azaldığına ait benzer sonuçlar Erturk et al (2007) tarafından Gisela 5 kiraz anacında ve Papadakis et al (2007) tarafından farklı kiraz çeşitlerinde de bildirilmiştir.…”

Tuzluluk, bitkilerde gelişim ve verimi sınırlayan önemli abiyotik stres koşullarının başında gelmektedir. Kiraz anaçlarının tuz stresi toleransları ile ilgili bilgiler oldukça sınırlıdır. Bu çalışmada, ülkemizde yetiştirilen üç kiraz anacının; Colt (Prunus avium x Prunus pseudocerasus), Gisela 5 (Prunus cerasus x Prunus avium) ve Maxma (Prunus mahaleb x Prunus avium), tuz stresine tolerans mekanizmaları in vitro koşullarda araştırılmıştır. Kiraz anaçlarının tuz stresine toleranslarını belirlemek amacıyla Murashige ve Skoog (MS) ortamına 0, 25 ve 50 mM NaCl uygulanmıştır. Anaçlarda; sürgün gelişimi, lipid peroksidasyonu (MDA), membran geçirgenliği (MG), toplam antioksidan aktivitesi (TAA), prolin içeriği, toplam klorofil içeriği, katalaz (CAT, EC 1.11.1.6) ve peroksidaz (POD, EC 1.11.1.7) antioksidan enzim izoformları ile Na ve Cl konsantrasyonları belirlenmiştir. Tuz stresi anaçların sürgün gelişimini ve toplam klorofil içeriğini kontrole göre azaltırken MDA içeriğini, MG, TAA ve prolin içeriğini artırmıştır. Anaçların stres koşullarında sürgün POD enzim aktivitesi artmış ve üç farklı POD izoformu elde edilmiştir. Maxma anacının POD aktivitesi diğer anaçların POD aktivitesinden daha düşük olmuştur. Anaçların CAT izoformlarında ise uygulamalar ve anaçlar arasında belirgin bir farklılık elde edilmemiştir. Bütün parametreler birlikte değerlendirildiğinde, NaCl stresine Maxma anacının hassas, Colt anacının orta derecede hassas ve Gisela 5 anacının da dayanıklı olduğu belirlenmiştir.
