We aimed to investigate the effects of NaCl and Na_2SO_4 on seed and pollen germination of tomato (Lycopersicon esculentum Mill.) in vitro. In addition, the effects of NaCl, Na_2SO_4, and CaCl_2 on yield and quality, plant growth, some physiological parameters, and the distribution of mineral composition in greenhouse grown tomato plants were investigated. Seed germination was affected by high salinity treatments (MS and 1/2 MS). Pollen germination and pollen tube length were significantly affected by salt forms and doses. Pollen germination was blocked by the above doses of 50 mM NaCl and 30 mM Na_2SO_4. In the greenhouse experiment, with …

Cropping Effects On Microbial Population And Nitrogenase Activity In Saline Arid Soil, Dilfuza Egamberdieva, Zulfiya Kucharova

Soil salinization is a major problem in irrigated agriculture. A field study was conducted in the Sariosiyo district in the Surkhandarya region of southeast Uzbekistan to evaluate soil nitrogenase activity and nitrogen-fixing bacteria populations in saline serozem soils under wheat, maize, and alfalfa, as well as from adjacent fallow land. Composite soil samples were randomly collected from depths of 0-10, 10-20, and 20-30 cm in autumn, winter, spring, and summer, which were then 2-mm sieved and subjected to selected microbial population analysis and enzymatic studies. The results showed that alfalfa contributed both to high nitrogenase activity and to a large …

Differences In Ostracoda (Crustacea) Assemblages Between Two Maar Lakes And One Sinkhole Lake In The Konya Region Of Turkey, Derya Akdemi̇r
Turkish Journal of Zoology
For this study, ostracod samples collected from a total of 9 stations in 2 maar lakes (Acı and Meke) and 1 sinkhole lake (Meyil) in Konya, Turkey were investigated. Accordingly, 14 ostracod taxa (Darwinula stevensoni, Candona angulata, Candona sp. 1, Candona sp. 2, Pseudocandona marchica, Cypria sp., Ilyocypris gibba, I. bradyi, I. monstrifica, Heterocypris salina, Potamocypris sp., Limnocythere sp., Paralimnocythere sp., and Cythereis sp.) belonging to 10 genera were identified. Among them, only 2 species (I. bradyi and P. marchica) were collected alive, while the others were found in sub-fossil form, and some shells of D. stevensoni were found containing …
