The effects of supplemental Ca 2? on membrane integrity and lipid composition of cowpea plants submitted to salt stress (75 mM NaCl) were evaluated. The experimental design was factorial (2 9 6 ? 1) corresponding to six saline treatments supplemented with CaCl 2 and six saline treatments supplemented with CaSO 4 , both at 0.5, 1.25, 2.5, 5.0, 7.5 and 10.0 mM, plus control treatment (plants grown in half-strength Hoagland's nutrient solution without supplemental calcium addition). Samples of leaves and root tips were analyzed for total lipid, glycolipid and fatty acid contents and membrane damage symptoms. Salt stress greatly reduced total lipid content in leaves and roots and caused great damage to membrane structures. In leaves, the glycolipid content was differently influenced by calcium treatments. Moreover, salinity increased the saturated/unsaturated fatty acid ratio in leaves and an increase in the concentration of calcium intensified this response. In roots, only saturated fatty acids were detected and their content was strongly influenced by salinity and very little by calcium treatments. Supplemental Ca 2? was unable to ameliorate the negative effects of salinity on the structural integrity and fluidity of plant membranes in cowpea.

“…Dolayısı ile kuraklık stresinin klorofil oranıyla negatif ilişkili olabileceği düşünülmektedir. Tüm ölçümlerde kuraklık stresiyle beraber, bor uygulaması sonucu klorofil miktarındaki azalma literatürde rapor edilen negatif ilişkiyi doğrulamaktadır [27]. Ayrıca, iyon dengesinin klorofil miktarını etkileyebileceğinden dolayı bu tür eksikliklerin dikkate alınması gerektiği vurgulanmıştır [36].…”

ÖzetBu çalışmada materyal olarak soya (Glycine max. L.) tohumları farklı bor bileşiklerinden oluşan, kontrollü koşullarda (25±2 C) yetiştirilmiştir. Çalışmada sırasıyla; potasyum tetraborat tetrahidrat, amonyum tetraborat tetrahidratt ve sodyum bor hidrürden 1 mg/l, lityum tetraborat tetrahidratt ve sodyum tetraborat dekahidrattan 100 mg/l olmak üzere 5 grup belirlenmiştir. Kullanılan dozlar daha önce yapılan ön çalışmada belirlenmiştir. Soya fideleri zamana bağlı olarak (kontrol, 3, 6, 9, 12, 15 L.) Under Drought Stress AbstractIn this study, soybean seeds (Glycine max. L.) were grown under controlled conditions (25±2 C) composed of different boron compounds. In the study, 5 groups were determined respectively as potassium tetraborate tetrahydrate (1 mg/1), ammonium tetraborate tetrahydrate (1 mg/1), sodium boron hydride (1 mg/1), lithium tetraborate tetrahydrate (100 mg/1), and sodium tetraborate decahydrate (100 mg/1). The doses used in this study were determined according to the results of a preliminary study. Soybean seeds were exposed to different amounts of drought stress based on time (control, 3, 6, 9, 12, 15, and 18 days).Chlorophyll, MDA, amounts of proline and ion in leaf samples were measured. In this study which was conducted in order to apply boron compounds against drought stress, it was determined that tolerance limits of soybean plant for boron compounds is very narrow. In the study, it was revealed that amounts of chlorophyll and proline increased in stress+potassium boron group while the amount of MDA was the same as in the control group. According to the results, it was determined that 0.1mg/l potassium tetraborate application was the most appropriate threshold level and that all the parameters supported each other against the drought and yielded the best results.

“…Semiarid and arid zones are particularly vulnerable to this increasing environmental issue (Murillo-Amador et al, 2006). Typically, salt stress triggers ion toxicity, osmotic stress, mineral deficiencies, and the combination of these physiological and biochemical disorders (Netondo et al, 2004).…”

“…Analysis of chlorophyll fluorescence is a nondestructive technique allowing a rapid assessment of in vivo photosynthetic activity (Netondo et al, 2004). In particular, fluorescence can furnish precious insights regarding the ability of a plant to tolerate abiotic stresses or the extent to which such constraints might have harmed PSII (Murillo-Amador et al, 2006), which is of high relevance when assessing the response of photosynthesis to environmental perturbations (Baker, 2008). Furthermore, chlorophyll-fluorescence data correlate with other physiological parameters, such as growth and yield .…”

Batis maritima is a promising halophyte for sand-dune stabilization and saline-soil reclamation. This species has also applications in herbal medicine and as an oilseed crop. Here, we address the plant response to salinity reaching up to two-fold seawater concentration (0-1000 mM NaCl), with a particular emphasis on growth, water status, mineral nutrition, proline content, and photosystem II integrity. Plant biomass production was maximal at 200 mM NaCl, and the plants survived even when challenged with 1000 mM NaCl. Plant water status was not impaired by the high accumulation of sodium in shoots, suggesting that Na + compartmentalization efficiently took place in vacuoles. Concentrations of Mg 2+ and K + in shoots were markedly lower in salttreated plants, while that of Ca 2+ was less affected. Soluble-sugar and chlorophyll concentrations were hardly affected by salinity, whereas proline concentration increased significantly in shoots of salt-treated plants. Maximum quantum efficiency (F v /F m ), quantum yield of PSII (U PSII ), and electron-transport rate (ETR) were maximal at 200-300 mM NaCl. Both nonphotochemical quenching (NPQ) and photochemical quenching (qP) were salt-independent. Interestingly, transferring the plants previously challenged with supraoptimal salinities (400-1000 mM NaCl) to the optimal salinity (200 mM NaCl) substantially restored their growth activity. Altogether, our results indicate that B. maritima is an obligate halophyte, requiring high salt concentrations for optimal growth, and surviving long-term extreme salinity. Such a performance could be ascribed to the plant capability to use sodium for osmotic adjustment, selective absorption of K + over Na + in concomitance with the stability of PSII functioning, and the absence of photosynthetic pigment degradation.
