Interaction between Glomus geosporum, Azotobacter chroococcum, and Bacillus coagulans and their ınfluence on Growth and nutrition of Melia azedarach L.

Arbuskular mycorrhizal mantarları, Glomus geosporum, azot fikse eden bakteri, Azotobacter chroococcum, ve mycorrhiza yardımcı bakteri Bacillus coagulans, arasındaki etkileşimi ve Melia azedarach L fidelerinin büyüme ve beslenmesi üzerine etkileri seralarda yapılan çalışma ile araştırılmıştır. M. azedarach fidelerine G. geosporum, A. chroococcum, ve B. coagulans mikroorgannizmalarının üçlü inokülasyonları bitki biomasını, N, P, Zn ve Cu alımını, biyohacim indeksini, kalite indeksini maksimum düzeyde artırmıştır. Ayrıca control bitki ile mukayese edildiği zaman bu bitkilerin kök zonlarında mikorhizal kök kolonizasyonu ve spor sayısında artış gözlenmiştir. Mikroorganizmalar ile inoküle edilen bitkiler ile control bitkiler arasında yapılan mukayese sonucu bakteri inoküle edilmiş bitkilerin fosfataz, dehidrojenaz gibi enzim aktviteleri de oldukça yüksek bulunmuştur. M. azedarach bitkisinin seralarda sağlıklı ve en güzel şekilde yetiştirilmesinde G. geosporum + A. chroococcum + B. coagulans organizmaların üçlü kombinasyonlarının en uygun mikrobial karışım olduğu sonucuna varılmıştır.

Glomus geosporum, Azotobacter chroococcum ve Bacillus coagulans arasındaki etkileşim ve bu etkileşimin Melia azedarach L. büyüme ve beslenmesine etkisi

A green house nursery study was conducted to assess the interaction between arbuscular mycorrhizal fungus, a nitrogen fixing bacterium, Glomus geosporum, Azotobacter chroococcum, and a mycorrhiza helper bacterium (MHB), Bacillus coagulans, in soil and their consequent effect on growth and nutrition of Melia azedarach L. seedlings. Triple inoculation of G. geosporum, A. chroococcum, and B. coagulans resulted in maximum plant biomass, N, P, Zn, and Cu uptake, and biovolume and quality index of M. azedarach seedlings. It also increased the mycorrhizal root colonization and spore numbers in the root zone soil of the inoculated plants over uninoculated control plants. The enzyme activity, namely acid phosphatase and dehydrogenase, in the root zone soil was found high in the 3-combination treatments and low in the uninoculated control. Triple inoculation with G. geosporum + A. chroococcum + B. coagulans proved to be the best microbial consortium for inoculating M. azedarach at nursery level in order to get healthy and vigorously growing seedlings.
