The Way

Four wetland species, Canna flaccida (canna), Iris versicolor (iris), Spartinia alterniflora (smooth cord grass), and Juncus effusus (rush), were planted into five different trade gallon container types. The container types used were no hole pots, four holes at the bottom of the pot, four holes half way up the side wall of the pot, four holes three-quarters of the way up the side wall of the pot, and pot-in-pot which consisted of trade gallon growing pots with four holes at the bottom of the pot placed inside a full gallon socket pot with no holes. Canna visual shoot and root rating were highest for the pot-in-pot treatment. Rush pot-in-pot plants had the highest growth indices, visual shoot, and root ratings compared to the remaining four pot types. Shoot count for iris was highest for the pot-in-pot containers. Container hole position did influence growth of smooth cord grass.

Indole 3 Acetic Acid

Production of indole-3-acetic acid (IAA), a key physiological feature of culturable, O2-tolerant bacteria associated with the freshwater macrophyte Juncus effusus L., was examined over a period of 2 years. Up to 74% of rhizobacteria identified and tested produced IAA. The number of indoleacetic acid producers decreased in winter. IAA was produced even when L-tryptophan, a precursor of IAA, was not added to the medium. Most of the IAA-producing strains were dominated by strains that were not identifiable to species level on the basis of API testing. Based on 16S rRNA gene sequencing and fatty acid analysis, it was found that IAA-producing rhizosphere bacteria associated with the freshwater wetland plant Juncus effusus L. are representatives of several families, including the Enterobacteriaceae, Pseudomonadaceae, Aeromonadaceae, Burkholderiaceae, and Bacillaceae. This study identifies numerous potentially important bacterial physiological groups of freshwater wetlands. Additionally, the study provides a baseline for monitoring and assessing the mutualistic relationships of wetland plants with rhizosphere bacteria in freshwater wetlands.Key words: wetlands, rhizosphere bacteria, IAA, 16S rRNA sequencing.
