Physiological And Antioxidant Response Of Three Cultivars Of Cucumber (Cucumis Sativus L.) To Salinity, Gökçen Baysal Furtana, Ruki̇ye Tipirdamaz
Turkish Journal of Biology
The effects of salinity on the growth, relative water content (RWC), chlorophyll content, inorganic ions, proline accumulation, lipid peroxidation and antioxidant enzymes, superoxide dismutase (SOD), ascorbate peroxidase (APOX), and catalase (CAT) of 3 cucumber (Cucumis sativus L.) cultivars (Çengelköy, Anadolu F1, and Beith Alpha) were investigated. Cucumber cultivars were grown in perlite culture and irrigated with half-strength Hoagland nutrient solution for a period of 35 days under controlled conditions. After this period, seedlings were treated with 150 mM NaCl solution and the plants were harvested on day 7 and day 14 of salt treatment. The fresh and dry weights, RWC, …
Response Of Photosynthesis In The Leaves Of Cucumber Seedlings To Light Intensity And Co2 Concentration Under Nitrate Stress, Xiaoyu Yang, Xiufeng Wang, Min Wei
Response Of Photosynthesis In The Leaves Of Cucumber Seedlings To Light Intensity And Co2 Concentration Under Nitrate Stress, Xiaoyu Yang, Xiufeng Wang, Min Wei
Turkish Journal of Botany
The effects of 2 nitrate levels, 14 (CK) and 140 mmol L^{-1} (T), on the leaf gas exchange variables of cucumber (Cucumis sativus L. cv. Xintaimici) seedlings grown in hydroponic culture were investigated. Photosynthetic light- and CO_{2}-response curves from CK and T seedlings were determined and used for the analysis of photosynthetic capacity. The results showed that nitrate stress resulted in a significant reduction of net photosynthesis of T seedlings compared with CK. At the same time, the apparent quantum yield, light-saturated net photosynthesis, carboxylation efficiency, and CO_{2}-saturated net photosynthesis in nitrate-stressed cucumbers also decreased significantly with the increase of …
A Native Glomus Sp. From Fields In Aydın Province And Effects Of Native And Commercial Mycorrhizal Fungi Inoculants On The Growth Of Some Vegetables, Ayhan Yildiz
Turkish Journal of Biology
Seventy soil samples were collected from 25 different plant varieties grown in fields in Aydın province. Arbuscular mycorrhizal fungi (AMF) were found in 59 soil samples; 58 of these were identified as Glomus sp. and 1 as Gigaspora sp. Due to its adaptation characteristics, growth rates, and colonization properties, Glomus sp. was selected for further study. The effects of Glomus sp. and BioOrganics (Glomus aggregatum, G. clarum, G. deserticola, G. intraradices, G. monosporus, G. mosseae, Gigaspora margarita, and Paraglomus brasilianum) on tomato, pepper, and cucumber plant development were evaluated. The indigenous Glomus sp. showed positive effects on cucumber and tomato …
