| Abstract/Contents: | "The growth of Agrostis palustris was evaluated in sand columns in response to black-layer formed by the interaction of cyanobacteria in the genera Oscillatoria (isolates OS-1 and OS-2) and Nostoc (NS-1) with the sulfate-reducing bacterium Desulfovibrio desulfuricans. All plants of A. palustris transplanted into black-layered sand columns survived, and the black-layer cleared adjacent to roots as they grew down in the column. Black-layer remained in the columns below the advancing root tips. After 10 weeks of growth, numerous roots showed discontinuous reddish-brown discoloration on their surfaces. Shoot growth of A. palustris was reduced in response to all cyanobacteria and D. desulfuricans isolates alone or in combination. Root growth was unaffected by the microorganisms with the exception of stimulation by OS-1 and inhibition by D. desulfuricans. Interaction of the microbes and the formation of black-layer is discussed relative to the growth of A. palustris." |
