Publication Impact of peltigera praetextata on zucchini grown in weathered p,p' -dde-contaminated soil and its responses(Springer Heidelberg, 2022-12-01) Akpınar, Aysegül; İşleyen, Mehmet; Cansev, Asuman; CANSEV, ASUMAN; Bursa Uludağ Üniversitesi/Ziraat Fakültesi.; AAH-4255-2019Terricolous lichens, located in soils, can change the bioavailability of polluted soil biologically, chemically and physically with their effective enzymatic content. Their effects are unknown especially on weathered p,p'-DDE-contaminated soil. However, we obtain new information by increasing our studies on this subject. In the present study, the impact of Peltigera praetextata (a terricolous lichen) on zucchini (Cucurbita pepo spp. pepo) grown in weathered p,p'-DDE-contaminated soil was shown via its physiological responses. At the same time, the physiological responses of Peltigera praetextata were also given. The results show that the growth and development of the zucchini grown in weathered p,p'-DDE-contaminated soil was positively affected by Peltigera praetextata. Peltigera praetextata was increased the bio-usefulness of weathered p,p'-DDE-contaminated soil with its effective enzyme contents. Moreover, Peltigera praetextata was able to cope with p,p'-DDE contamination with the strong antioxidative defence system.Publication Effects of the lichen Peltigera canina on Cucurbita pepo spp. pepo grown in soil contaminated by DDTs(Springer Heidelberg, 2020-11-19) Akpınar, Ayşegül; Cansev, Asuman; İşleyen, Mehmet; CANSEV, ASUMAN; Bursa Uludağ Üniversitesi/Ziraat Fakültesi/Bahçe Bitkileri Bölümü.; 0000-0002-3353-846X; AAH-4255-2019Lichens consisting of a symbiotic association of green algae or cyanobacteria and fungi are found in a variety of environmental conditions worldwide. Terricolous lichens, located in soils, affect the living and lifeless environment of the soil due to their effective secondary metabolite and enzymatic content. Terricolous lichens can increase the biological, chemical, and physical usefulness of soil. However, their effects in ensuring the bioavailability of contaminated soil are not known, especially on soil pollution caused by DDTs (p,p '-DDE, p,p '-DDD, p,p '-DDT). This research focuses on the effect of terricolous lichens on zucchini (Cucurbita pepo spp. pepo) grown in soil contaminated by DDTs, utilizing their secondary metabolite and enzymatic contents. Firstly, Peltigera canina, a terricolous lichen species, was added to soil contaminated by DDTs as powdered and intact thallus. After lichen addition to soil, zucchini was planted in. The oxidative stress and antioxidative enzyme activities of zucchini were measured. According to the results, P. canina treatments have a positive effect on the growth and development of zucchini, although oxidative stress was observed. Also, it was determined that powdered application had more effective results than intact thallus application.Publication Application of choline and glycine betaine alters levels of total phosholipids in olea europaea L. related to cold hardiness(Federation Amer, 2013-04-01) Cansev, Asuman; Gülen, Hatice; İpek, Meryem; Barut, Erdoğan; CANSEV, ASUMAN; Gülen, Hatice; İPEK, MERYEM; BARUT, ERDOĞAN; Uludağ Üniversitesi; 0000-0001-7586-3108; 0000-0002-3353-846X; AFW-5375-2022; AAH-4255-2019; AAE-6913-2019; AAH-3233-2021Publication Physiological and molecular responses of roots differ from those of leaves in spinach plants subjected to short-term drought stress(Elsevier, 2022-12-01) Akpınar, Aysegül; Cansev, Asuman; CANSEV, ASUMAN; 0000-0002-3353-846X; AAQ-8139-2021; AAH-4255-2019In this study, physiological responses as well as changes in expressions of specific proteins (dehydrin [DHN] and phospholipase D alpha 1 [PLD alpha 1]) were determined in leaf and root tissues of Spinacia oleracea L.cv. Matador plants under different levels of drought stress. Spinach plants grown in the plant growth chamber were exposed to two levels of drought stress (Moderate Stress [MS]: 50% Field Capacity [FC] and Severe Stress [SS]: 25% FC) and compared with no stress conditions (Control: 100% [FC]) for a period of 10 days. Results revealed that the roots and leaves of spinach plants responded differently to drought stress, probably due to different antioxidant activities and accumulation of specific proteins (DHN and PLD alpha 1). Moderate or severe drought stress did not alter the oxidation parameters in leaves of S. oleracea L. cv. Matador plants while significant changes associated with oxidative stress were observed in roots. Dehydrin polypeptides (75 and 50 kDa for leaves and 75 kDa for roots) and PLD alpha 1 polypeptides (22 kDa in leaves; 52 kDa and 28 kDa in roots) have been observed to accumulate following drought exposure. The accumulation of these polypeptides was associated with physiological responses of spinach plants which provide evidence for their contribution to the acclimation process in early drought stress. These data suggest that tissues of spinach plant respond differently against different levels of drought stress and that the response is associated with altered expressions of DHN and PLD alpha 1 polypeptides.Publication The effects of different irrigation levels and nitrogen doses on growth, quality and physiological parameters of warm-season turfgrasses(Galenos, 2023-01-01) Yonter, Fikret; Zere Taskin, Sinem; Kesici, Muge; Candogan, Burak Nazmi; Cansev, Asuman; Bilgili, Ugur; Candogan, Burak Nazmi; CANDOĞAN, BURAK NAZMİ; Cansev, Asuman; CANSEV, ASUMAN; Bilgili, Ugur; BİLGİLİ, UĞUR; Yonter, Fikret; YÖNTER, FİKRET; ; Bursa Uludağ Üniversitesi/Ziraat Fakültesi/Tarla Bitkileri Bölümü.; Bursa Uludağ Üniversitesi/Ziraat Fakültesi/Biyosistem Mühendisliği Anabilim Dalı.; 0000-0002-2243-2993; GRO-3789-2022; AAH-4255-2019; AAH-1539-2021; AAH-3102-2021This research was conducted to determine to effects of different irrigation levels and nitrogen doses (ND) on the various warm-season turfgrasses at the Agricultural Training and Research Centre of the Bursa Uludag University Faculty of Agriculture for two years in a row. The experimental design was the randomized blocks in a split-split plot design with three replications. The main plot was irrigation levels (I1=25%, I2=50%, I3=75%, and I4=100% of pan evaporation), subplots were turfgrass species [hybrid Bermudagrass (Cynodon transvaalensis x Cynodon dactylon) cv. Tifdwarf, seashore paspalum (Paspalum vaginatum Sw.) cv. Seaspray, zoysiagrass (Zoysia japonica Steud.) cv. Zenit], and sub subplots were ND's (monthly 0.0, 1.25, 2.5, and 5.0 g N m-2). Visual turfgrass color and quality, clipping yield, leaf relative water content (RWC), loss of turgidity (LT), chlorophyll content (CC), and electrolyte leakage were measured. According to the results, significant differences were determined among irrigation levels, turfgrass species, and ND's for color, quality, clipping yield and physiological parameters. Turfgrass visual color, quality and clipping yield were shown to decrease significantly with decreases in irrigation water and N fertilizer. The study findings demonstrated that under a non-limiting water supply, irrigation could be decreased by adjusting N fertilizer rates with I3N3 treatments can maintain acceptable turfgrass visual color and quality under Mediterranean climatic conditions. In addition, at 25% (I1) deficit irrigation level, leaf RWC, CC decreased significantly, while an increase was determined in LT. This research indicated that under 75% (I3) deficit irrigation and N3 ND, acceptable quality can be maintained with 'seaspray' seashore paspalum under Mediterranean climate performed.Publication Bioaccessibilities of K, P, Fe and B minerals in oleaster flour as a novel food ingredients(Federation Amer Soc Exp Biol, 2013-04-01) Şahan, Yasemin; Cansev, Asuman; Çelik, Güler; Göçmen, Duygu; ŞAHAN, YASEMİN; CANSEV, ASUMAN; GÖÇMEN, DUYGU; Uludağ Üniversitesi; 0000-0002-3353-846X; ABE-6748-2020; KDP-3344-2024; AAH-4255-2019Publication Characterization of phytochemical and functional properties of endemic edible Allium tuncelianum and comparison with commonly cultivated garlic, onion and leek crops(Springer, 2023-01-13) İPEK, MERYEM; ŞAHAN, YASEMİN; CANSEV, ASUMAN; Cansev, Asuman; İPEK, AHMET; Ipek, Ahmet; Altınseker Acun, Deniz Zahide; Bursa Uludağ Üniversitesi/Ziraat Fakültesi.; AAH-3233-2021; ABE-6748-2020; AAH-4255-2019; AAK-4655-2021Edible Allium tuncelianum ([Kollman] Ozhatay, Matthew and Siraneci), endemic to Turkey, has received increased attention in recent years because of its appealing characteristics, such as garlic (A. sativum L.)-like odor and single-clove solid bulb structure with few peels, which could be advantageous in the food processing industry. The aims of this study were to determine chemical composition, phytochemicals (alliin, allicin, phenolics), antioxidant capacity, and bioaccessibility of total phenolic content and antioxidant capacity in A. tuncelianum and to compare with the values in commonly cultivated Allium species: garlic, onion (A. cepa L.), and leek (A. porrum L.) to reveal its nutritional and health beneficial properties. The chemical composition of A. tuncelianum was comparable with that of garlic, and its dietary fiber content was three times higher than that of garlic. Alliin and allicin organosulfur compounds, which give garlic its distinct flavor and odor, were detected in all analyzed A. tuncelianum genotypes although their values lower than the amounts detected in garlic genotypes. However, alliin and allicin were not detected in any onion and leek genotypes. A. tuncelianum genotypes had higher total phenolic contents with over 78 percent bioaccessibility rates than garlic, onion, and leek. The antioxidant capacity of A. tuncelianum was comparable to those of cultivated Allium species. Our results suggested that A. tuncelianum can be considered a promising new health-enhancing crop for human nutrition.(GRAPHICS)
