Arbuscular Mycorrhizal Fungi in Sustainable Agriculture
(Elsevier, 2024) Demir, S.; Rezaee Danesh, Y.; Demirer Durak, E.; Najafi, S.; Boyno, G.
The 20th century has been accompanied by the increasing growth in agricultural production, the use of chemical inputs, especially nitrogen and phosphorus fertilizers, as well as the development of new methods in genetics and plant breeding. In natural ecological conditions, the rhizosphere soils have different types of living organisms, including mycorrhizal fungi, bacteria, and actinomycetes, that play a significant role in plant growth and development, plant nutrition as well as tolerance against biotic and abiotic stresses. Among them, arbuscular mycorrhizal fungi (AMF) have a significant symbiotic relationship with different types of plants in most natural habitats. These fungi play a direct role in improving the growth and development of plants in agricultural ecosystems by absorbing phosphorus and other mineral nutrients from the soil. Also, the role of these fungi in reducing the effects of various biotic and abiotic stresses, bioremediation of contaminated soils, protecting plants against pathogens, increasing biodiversity in host plants, and improving soil fertility and structure has also been validated. AMF have a symbiotic relationship with the majority of plants, such as cereals, vegetables, and fruit trees, and thus play a significant role in sustainable agricultural systems. Proper management of these fungi can be very important in improving sustainable agricultural practices. In this chapter, the role and benefits of mycorrhizal fungi in sustainable agricultural development systems are emphasized and discussed. © 2024 Elsevier Inc. All rights reserved.
Effect of Some Trichoderma Species on Germination Rate of Nettle (Urtica Dioica L.)
(Centenary University, 2019) Güneş, H.; Demirer Durak, E.; Yeşilova, A.; Demir, S.
Plants belonging to the Urticaceae family, including 48 genera and 1050 species in the world, are used extensively in many areas from past to present for different purposes. The aim of this study was to determine the parameters that promote germination of U. dioica plant in order to contribute to the studies aimed at increasing the use of nettle in large areas for agricultural and pharmacological purposes. Trichoderma harzianum, T. virens, T. asperellum fungi, Hoagland nutrient solution and Potato Dextrose Agar (PDA), Water Agar and blotter germination medium were used to determine the effects on germination of nettle seeds. The study was conducted in vitro with 4 replications. As a result of the experiment, it was determined that all Trichoderma species promoted germination of nettle plant with nutrient solution in blotter medium and increased by 62.5% compared to control. In this context, it has shown that will be beneficial transferring this effect seen in vitro conditions to in vivo conditions. © 2019, Centenary University. All rights reserved.
Intercourse of Arbuscular Mycorrhizal Fungus and Putrescine Treatments on Agro Morphological and Biochemical Properties of Strawberry Festival Cv
(Springer, 2025) Kuru Berk, S.; Gündoğdu, M.; Demirer Durak, E.
Putrescine (Put) and arbuscular mycorrhizal fungus (AMF) play an effective role in plant growth and development. However, although studies on the use of putrescine in field conditions are limited, there are no studies on its use with AMF. In this research, the effects of putrescine and AMF applications on yield, plant and fruit development, fruit biochemicals, flowering, and harvest were investigated in strawberry Festival cultivar. Two doses of putrescine (100 and 150 ppm), two types of AMF, (Funneliformis mosseae/FM and Gigaspora margarita/GM), and their interactions were used. The results show that putrescine affected AMF colonization and mycorrhizal dependence. Especially in F. mosseae species, it was observed that colonization increased with putrescine interactions. Also, highest yield was determined as 346.12 g in G. margarita and 150-ppm Put interaction application. The interaction application of F. mosseae and 150-ppm putrescine had the highest amount of vitamin C with an increase of 78% compared to the control. Again, it was observed that this application had the highest amount of catechin and rutin (5.385 and 1.055 mg 100 g−1, respectively). However, only putrescine applications came to the fore in terms of the development of the crown length of the plant and the sugar content. It was determined that G. margarita applications extended the harvest period in this study. These results showed that the yield, vegetative growth, and fruit biochemical content of strawberry could be increased with the interaction application of F. mosseae and 150-ppm putrescine. All in all, a different perspective has been brought to the use of putrescine and mycorrhiza in agricultural production and its positive effects have been revealed. © The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature 2023.
