Integrated Application Of Plant Growth Promoting Rhizobacteria And Biochar Improves Salt Tolerance In Eggplant Seedlings, Razi̇ye Kul
Turkish Journal of Agriculture and Forestry
A pot study was conducted to determine the effects of the combination of plant growth promoting rhizobacteria (PGPR) and biochar on the growth, physiological, and biochemical characteristics of eggplant seedlings under salinity stress. The greenhouse experiment included two salinity levels of NaCl [S0 (0 mM NaCl) and S1 (100 mM NaCl)], three biochar levels [B0 (non-biochar), B1 (5%) and B2 (10%)] and two PGPR [R0 (non-PGPR), R1 (combination of Bacillus megaterium TV-6D, Paenibacillus polymyxa KIN- 37, and Pantoea agglomerans RK92). Results showed that plant growth, relative leaf water content (LRWC), and chlorophyll content of eggplant seedlings decreased significantly, while malondialdehyde …
Ameliorative Effects Of Nitric Oxide On Growth, Physiology And Biochemistry Of Chickpeaplants Under Salinity Stress, Esi̇n Dadaşoğlu
Ameliorative Effects Of Nitric Oxide On Growth, Physiology And Biochemistry Of Chickpeaplants Under Salinity Stress, Esi̇n Dadaşoğlu
Turkish Journal of Agriculture and Forestry
Salinity is one of the major environmental constraints affecting agriculture in major regions of the world. This study was conducted to evaluate the effect of exogenous nitric oxide (NO) treatments on two chickpea cultivars (Cagatay and Inci) under salt stress conditions. Different NO doses (0. 75 and 100 μM sodium nitroprusside (SNP)) as an NO source were applied to chickpea plants grown under saline (presence of 50 and 100 mM of NaCl) and nonsaline conditions. In this study, plant shoot fresh and dry weight, root fresh and dry weight, chlorophyll a, b, total chlorophyll, chlorophyll reading value (CRV), relative water …

Salt Stress By Nacl Alters The Physiology And Biochemistry Of Tissue Culture-Grownstevia Rebaudiana Bertoni, Rabia Javed, Ekrem Gürel
Turkish Journal of Agriculture and Forestry
This study reports the response to salinity stress (100 mM, 200 mM, and 300 mM NaCl concentration) exposure of the commercially valuable medicinal plant Stevia rebaudiana during micropropagation for 4 weeks. The significant enhancement of physiological parameters, steviol glycosides (SGs), i.e. rebaudioside A and stevioside, as examined by high-performance liquid chromatography, and nonenzymatic antioxidant activities, i.e. total phenolic content, total flavonoid content, total antioxidant capacity, total reducing power, and DPPH-free radical scavenging activity, was observed during the shoot formation process under up to 100 mM NaCl stress. Callus formation produced similar results regarding physiology and antioxidant assays, except that it …
Silicon-Mediated Oxidative Stress Tolerance And Genetic Variability In Rice(Oryza Sativa L.) Grown Under Combined Stress Of Salinity And Boron Toxicity, Muhammad Ansar Farooq, Zulfiqar Ahmad Saqib, Javaid Akhtar
Silicon-Mediated Oxidative Stress Tolerance And Genetic Variability In Rice(Oryza Sativa L.) Grown Under Combined Stress Of Salinity And Boron Toxicity, Muhammad Ansar Farooq, Zulfiqar Ahmad Saqib, Javaid Akhtar
Turkish Journal of Agriculture and Forestry
The benefits of silicon (Si) in improving crop fitness by biotic and abiotic stress resistance are widely reported. However, investigations about its protective mechanisms for plants facing multiple stresses are very limited. Two contrasting rice cultivars, KS-282 (salt-tolerant) and IRRI-6 (salt-sensitive), were grown in a pot experiment to study the interrelation between Si supplementation (0 and 150 mg kg-1) and boron (B) toxicity (0 and 2.5 mg kg-1) under salinity stress with emphasis on growth response, mineral contents, physiology, and enzymatic antioxidant system response. The results revealed that adverse growth conditions, particularly the combined stress of salinity and B toxicity, …

Turkish Journal of Agriculture and Forestry
The normalized difference vegetation index (NDVI) is gaining popularity as a complementary selection tool, even though it requires an instrument not readily available in the developing world. We evaluated several parameters (originating from the analysis of digital photos using BreedPix software) as potential selection criteria in 23 winter wheat yield trials grown over 4 years at 2 sites. NDVI and digital photos were taken at key development stages from stem elongation to maturity. The correlations between digital photo parameters a and u and grain yield, as well as correlations between NDVI and grain yield within individual trials, varied depending on …
