tailieunhanh - A native Glomus sp. from fields in Aydın province and effects of native and commercial mycorrhizal fungi inoculants on the growth of some vegetables

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. | Turk J Biol 34 (2010) 447-452 © TÜBİTAK doi: 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 Department of Plant Protection, Faculty of Agriculture, Adnan Menderes University, 09100 Aydın - TURKEY Received: Abstract: 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 plant growth, but there was no significant difference in pepper plant growth when compared with the BioOrganics treatments. Glomus sp. colonization rates on roots of plants were 71% in cucumber, 72% in tomato, and 61% in pepper, and BioOrganics colonization rates were 47% in cucumber, 39% in tomato, and 36% in peppers. Key words: Glomus sp., tomato, cucumber, pepper Aydın İli tarım alanlarından elde edilen Glomus sp. ile mikorizal bir preparatın bazı sebzelerin gelişimine etkisi Özet: Bu çalışmada Aydın İli ve ilçelerinden, 25 farklı bitki türünün yetiştirildiği alanlardan toplam 70 toprak örneği alınmıştır. Bu toprak örneklerinin 59’unda mikorizal fungus saptanmış ve bunların 58’i Glomus sp. ve biri de Gigaspora sp. olarak tanılanmıştır. Uyum yetenekleri, gelişme hızları ve kolonizasyon durumları gibi özellikleri dikkate alınarak seçilen yerel Glomus sp. ve BioOrganics (Glomus aggregatum, G. clarum, G. deserticola, G. intraradices, G. .
