    The effects of irrigation with reclaimed wastewater on heavy metal accumulation and plant development in lettuce
    (Parlar Scientific Publications (P S P), 2020-01-01) Akbudak, Nuray; Biçen, Nafiz; AKBUDAK, NURAY; Biçen, Nafiz; Bursa Uludağ Üniversitesi/Ziraat Fakültesi/Bahçe Bitkileri Bölümü; AAH-5045-2021; EMR-8319-2022
    Due to the increasing growth of the city, agricultural land has begun to take place in and around the living areas. This situation also increases the need for irrigation water available in agriculture. This study assessed the impacts of lettuce irrigation with treated effluents, as compared to domestic water (DW) irrigation, on plant physiological structure and crop productivity. The treated effluents reused for irrigation were produced in two Municipal Wastewater Treatment Plants utilizing two discrete tertiary treatments (physical purification and biological treatment). The experiment was conducted for five months on the agriculture form by using lettuce leaf type and head type lettuce. In all plant groups (the productivity, weight, length, diameter, root fresh and dry weight, root diameter), quality characteristics (deformable and number of marketable leaves per plant, total chlorophyll) and heavy metal contents (Ni, Pb, Cd, and Co) were determined. Application of treated wastewater (TWW) increased marketable yield, the number of leaves per plant, plant height, and diameter. The highest yield of lettuce plants was obtained with the treated wastewater in head type lettuce. TWW irrigation also increased the growth parameters such as the number of leaves, fresh root weight, dry weight, and total chlorophyll. Results show a high influence of TWW in nitrate content of lettuce. Results on Ni, Pb concentrations show higher values for "Festival" (leaf type) and "Bombola" (head type) plants irrigated with TWW than DW. Cd and Co values in the plants subjected to DW and TWW were similar. The values of total leaf chlorophyll content in all plants irrigated with TWW were higher than for those irrigated with DW. Results show that heavy metal accumulation, an important criterion for the use of treated waste water in agriculture, may differ in lettuce varieties. By choosing heavy metal tolerant varieties, treated wastewater can be used for long-term in sustainable agriculture.

    Farklı domates çeşitlerinde zararlılara karşı savunma yapıları olan trikom yoğunluğunun ve acylsugar konsantrasyonunun belirlenmesi
    (Bursa Uludağ Üniversitesi, 2024-02-09) Gök, Narin; Özkan, Simge; Çobanoğlu, Sultan; KUMRAL, NABİ ALPER; AKBUDAK, NURAY; GENÇER, NİMET SEMA; Bursa Uludağ Üniversitesi/Ziraat Fakültesi/Bahçe Bitkileri Bölümü; 0000-0001-9442-483X; 0000-0003-2669-5667; 0000-0001-8053-5002
    Ülkemizde domates yetiştiriciliği ekonomik getiri ve beslenme yönünden önem arz etmektedir. Domates yetiştiriciliğindeki önemli sorunlardan biri zararlılar (böcek ve akar) nedeniyle yüksek ürün kayıplarıdır. Günümüzde bazı domates hastalıkları ve nematot zararlılarına karşı dayanıklı domates çeşitleri ruhsatlanmasına karşın; diğer zararlılara karşı dayanıklı tescilli çeşitler henüz kaydedilmemiştir. Domateslerde, böceklerin ve akarların zararına hatta biyolojik mücadele etmenlerinin aktivitesine karşı olumsuz olan unsurlardan biri de domatesin vejatatif organlarında bulunan keseli ve kesesiz trikomlardır. Kesesiz trikomlar bu canlıların vücudunu tahrip ederek olumsuz etki yaratırken; keseli trikomların içinde bulunan acylsugar’ın bunlar üzerinde zehir veya kaçırıcı etkisi bulunmaktadır. Bundan dolayı, bu çalışmada 49 domates çeşidinde bulunan trikom yapıları ve keseli trikomlardan salgılanan acylsugar konsantrasyonları araştırılmıştır. İncelenen domates çeşitlerindeki trikomların tiplerine göre yoğunluklarının saptanması zararlılara dayanıklı çeşitlerin belirlenmesi için temel bilgi sağlarken; aynı zamanda doğal düşmanların etkinliğini sınırlaması açısından da bilgi verilmiştir. Çalışmada yaprak, sap ve dallarda tip IV ve tip VI keseli; tip III ve tip V kesesiz trikomların yoğunlukları tespit edilmiştir. Her bir vejatatif organ ayrı ayrı değerlendirildiğinde farklı trikom tiplerinin yoğunluklarının çeşitlere bağlı önemli düzeyde değişiklik gösterdiği saptanmıştır. Ward’ın minumum varyans analizi metotuna göre her tipteki trikom yoğunlukları düşük, orta ve yüksek olarak kümelenmiştir. İncelenen çeşitler arasından bazılarının hem keseli hem de kesesiz trikom açısından düşük yoğunluğa sahip olduğu belirlenmiştir. Benzer istatistiki farklılıklar, keseli trikomlarda bulunan acylsugar içerikleri açısından da ortaya konmuştur.

    The effect of irrigation of pickling cucumber with urban wastewater on product quality and heavy metal accumulation
    (Springer, 2022-08-22) Akbudak, Nuray; Üstün, Gökhan Ekrem; AKBUDAK, NURAY; ÜSTÜN, GÖKHAN EKREM; Bursa Uludağ Üniversitesi/Ziraat Fakültesi/Bahçe Bitkileri Bölümü; Bursa Uludağ Üniversitesi/Mühendislik Fakültesi/Çevre Mühendisliği Bölümü; 0000-0002-7126-6792; AAG-8439-2021; EKS-0323-2022
    Pickled cucumber is one of the vegetables that needs water frequently during its cultivation and is processed and evaluated, and it is consumed high all over the world. In arid and semi-arid regions, wastewater is commonly used for vegetables and forage crop irrigation. In this study, a comparative field study was carried out using untreated wastewater (U), treated wastewater (T), and tap water for control (C) irrigation for the growing of cucumber pickled plants. Plant phenological and some growth parameters, fruit quality parameters, fruit, and leaf color, photosynthetic pigments, phenolic compound, vitamin C and heavy metal (HM) contents (Cr, Ni, Cd, Pb, Cu) in different parts of the plant were defined. In addition, crop productivity was measured by the means of fruit weight and diameter, and length. The results show that plant length and yield of pickling cucumbers increased by 40.90% in U, and 4.39% in T. The plants in U applications were started to harvest 5 days ago when compared with the others. On a positive note, U led to an increase in vitamin C levels and phenolic compounds. Collectively, the data suggest that U can help add value to pickling cucumber by increasing its antioxidant activity as compared to other irrigation water sources. The accumulation in the leaves was Ni > Cr > Cu > Pb > Cd, respectively. Based on the results, this study concludes that it is possible to use wastewater for cucumber irrigation. Since the edible parts of pickling cucumber are consumed after processing, they do not pose a risk to public health. This study may provide a basis for application of using untreated wastewater in high quality cucumber production.
