This study evaluated seedling traits (shoot/root length, fresh and dry weights of shoots/roots, number of leaves, shoot diameter), phosphorus (P) content, mycorrhizal colonization (MC), and relative mycorrhizal dependency (RMD) of 21 common bean genotypes inoculated by 4 different arbuscular mycorrhizal fungi (AMF) Glomus intraradices (Gi), Glomus mosseae (Gm), Gigaspora margarita (Gim), and commercial AMF (cAMF) in a growth chamber under controlled growing conditions. | Turkish Journal of Agriculture and Forestry Turk J Agric For (2017) 41: 1-9 © TÜBİTAK doi: Research Article Variations in response of determinate common bean (Phaseolus vulgaris L.) genotypes to arbuscular mycorrhizal fungi (AMF) inoculation 1, 2 3 4 2 Çeknas ERDİNÇ *, Emre DEMİRER DURAK , Aytekin EKİNCİALP , Suat ŞENSOY , Semra DEMİR 1 Department of Agricultural Biotechnology, Faculty of Agriculture, Yüzüncü Yıl University, Van, Turkey 2 Department of Plant Protection, Faculty of Agriculture, Yüzüncü Yıl University, Van, Turkey 3 Başkale Vocational School, Yüzüncü Yıl University, Van, Turkey 4 Department of Horticulture, Faculty of Agriculture, Yüzüncü Yıl University, Van, Turkey Received: Accepted/Published Online: Final Version: Abstract: This study evaluated seedling traits (shoot/root length, fresh and dry weights of shoots/roots, number of leaves, shoot diameter), phosphorus (P) content, mycorrhizal colonization (MC), and relative mycorrhizal dependency (RMD) of 21 common bean genotypes inoculated by 4 different arbuscular mycorrhizal fungi (AMF) [Glomus intraradices (Gi), Glomus mosseae (Gm), Gigaspora margarita (Gim), and commercial AMF (cAMF)] in a growth chamber under controlled growing conditions. With the exception of shoot diameter, inoculated plants had better seedling traits than noninoculated plants. P content of shoot was also higher in inoculated plants than in noninoculated plants. Of the 20 genotypes and Nadide cv. examined, 5 responded positively and 3 responded negatively to inoculation with all AMF types. Great variations in RMD and MC were observed, with the highest RMD and MC in the T120 () and T71 () genotypes and the lowest in the V77 () and V78 () genotypes. Positive correlations were found between RMD and seedling traits, with the exception of shoot length as well as root length, P content, and colonization.
