Boron Toxicity and Pgpr Phytoremediation Effects on Physiological and Biochemical Parameters of Medical Sage (Salvia Officinalis L.)
(Polish Society Magnesium Research, 2022) Yolci, Muhammed Said; Tuncturk, Ruveyde; Eryigit, Tamer; Tuncturk, Murat
In this study, the effects of boron doses (0=control, 5, 10, 20 mM) and some beneficial rhizobacteria (Azospirillum lipoferum, Bacillus megaterium, Frateuria aurentia) on the physiological and biochemical parameters of medicinal sage (Salvia officinalis L.) were investigated. The study was carried out in factorial order in a completely randomized experimental design with four replications in a controlled climate chamber. In the study, chlorophyll a, chlorophyll b, total chlorophyll, total carotenoid, total anthocyanin, nitrogen balance index, MDA, relative water in leaf tissues, ion leakage, membrane durability, total phenolic substance, total flavonoid substance, and total antioxidant activity parameters were investigated. Depending on the applied boron doses, increases were observed in total phenolic, total flavonoid, total carotenoid, ion leakage, and MDA values. In contrast, decreases in the nitrogen balance index and membrane durability were observed. It has been determined that PGPR applications effectively reduce the damage of boron by increasing the total anthocyanin, total flavonoid, chlorophyll b, total chlorophyll amounts, and
The Effect of Biofertilizer Applications and Inorganic Fertilization on Some Agronomic, Quality and Biochemical Properties of Safflower (carthamus Tinctorius L.)
(2022) Yolci, Muhammed Said; Tunçtürk, Rüveyde
Bu çalışma, Van ekolojik koşullarında biyogübre uygulamaları ve inorganik gübrelemenin aspir (Carthamus tinctorius L.) bitkisinin bazı agronomik, kalite ve biyokimyasal özellikleri üzerine etkilerini belirlemek amacıyla 2020 ve 2021 yılları yazlık yetiştirme döneminde sulu koşullarda yürütülmüştür. Araştırma Yüzüncü Yıl Üniversitesi Ziraat Fakültesi deneme alanlarında 'Tesadüf Bloklarında Bölünmüş Parseller Deneme Deseni'ne göre 3 tekrarlamalı olarak düzenlenmiştir. Denemede, beş farklı biyogübre (kontrol (B0), Frateuria aurantia (B1), Bacillus megaterium (B2), Azospirillum lipoferum (B3), Chlorella saccharophilia (B4) ve Lactobacillus casei + Rhodopseudomonas palustris + Saccharomyces cerevisiae + Lactococcus lactis mikroorganizmalarından oluşan karışım gübre (B5)) ile farklı NP (azot + fosfor) gübre dozları (NP0 = kontrol, NP50 = 7.5 kg/da AS + 4 kg/da TSP, NP100 = 15 kg/da AS + 8 kg/da TSP) dozları uygulanmıştır. Araştırmada, bitki boyu, ilk dal yüksekliği, bitki başına dal sayısı, bitki başına tabla sayısı, tabla çapı, tabla başına tohum sayısı, bin tohum ağırlığı, tohum verimi, taç yaprak verimi, ham yağ oranı, ham yağ verimi, toplam boyar madde oranı, toplam fenolik madde miktarı, toplam flavonoid madde miktarı ve toplam antioksidan aktivite parametreleri incelenmiştir. Araştırmada, birleştirilmiş yıllar ortalamasına göre en yüksek tohum verimi 260.22 kg/da ile NP100 gübre dozu ve B1 bakteri uygulamalarının yapıldığı parsellerden, en düşük tohum verimi ise 112.40 kg/da ile NP0 × B0 interaksiyonundan tespit edilmiştir.
Effect of Different Boron Concentrations and Rhizobacteria Applications on Physiological and Biochemical Properties of Purple Basil (Ocimumbasilicum) Plant
(Polish Society Magnesium Research, 2022) Yolci, Muhammed Said; Tuncturk, Ruveyde; Tuncturk, Murat; Eryigit, Tamer
It is known that applications of boron, which is known to play an essential role in nutrient transport by plant membranes, can affect the accumulation and use of other plant nutrients as a regulator or an inhibitor. Thus, in this study, the effects of boron doses (0-control, 5, 10, 20 mM) and some beneficial rhizobacteria (Azospirillum lipoferum, Bacillus megaterium, and Frateuria aurentia) on seedling growth, physiological, and biochemical parameters of purple basil (Ocimum basilicum) were investigated. The study was carried out in as a factorial experi-ment in a completely randomized design with four replications in a controlled climate chamber. In the study, plant root, seedling length, root and seedling fresh-dry weight, total chlorophyll, carotenoid, anthocyanin, flavonol, nitrogen balance index, MDA, relative water in leaf tissues, ion leakage, and membrane stability parameters were investigated. It was observed that all growth parameters were negatively affected by increasing boron doses. In contrast, while ion leakage, total flavonol, carotenoid, anthocyanin, and MDA contents increased, membrane stabil- ity, total chlorophyll content, and nitrogen balance index contents decreased. Rhizobacteria applications were found to be effective in reducing toxic boron damage in root length and seed-ling fresh weight, increasing total chlorophyll, and anthocyanin contents, and decreasing boron toxicity by reducing lipid peroxidation compared to control.
Investigation the Effect of Drought Stress on Tolerant and Resistant Rice (Oryza Sativa L.) Varieties in Terms of Morphologic and Genetic Characters
(Springer, 2023) Arvas, Yunus Emre; Yolci, Muhammed Said; Marakli, Sevgi
Drought associated with global warming is a major limiting factor for crop production. This abiotic stress affects the quality and yield of rice (Oryza sativa L.) which is a model organism and also one of the major consumed products all over the world. In this study, we aimed to analyse morphologic (root length, shoot length, root wet weight, shoot wet weight, root dry weight and shoot dry weight) of rice varieties (Dhan 65, Dhan 71, Kiziltan and Karacadag local rice) grown under drought stress during 21 days. For genetic properties, Hopi and Osr30 retrotransposon movements were investigated by using IRAP marker technique. Depending on the decreasing in the amount of water, we observed that all growth parameters showed variable results in four varieties. Moreover, IRAP-PCR indicated different polymorphism ratios among samples. These rates were 0-75% for Hopi and 0-50% for Osr30. As far as we know, this is the first detailed report on dhan 65, dhan 71, kiziltan and Karacadag local rice varieties grown under drought stress.
