Research on the promoting effect on the plant growth of Hedera helix ‘Woerner’ in a hydroponic system after the application of several microorganisms has been done. Dresden University of Applied Sciences, Germany, is making investigations about hydroponic facade greenery with Hedera since the year 2007 (Wolter et al., 2008) and is looking for further optimization of those new systems. Arbuscular mycorrhiza - INOQ Agri (Glomus etunicatum, G. intraradices, G. claroideum) - Plant Growth Promoting Rhizobacteria - Bacillus subtilis FZB24® fl. (Bacillus subtilis) and RhizoVital®42 fl. (Bacillus amyloliquefaciens) – and Plant Growth Promoting Bacteria – Enterobacter radicincitans – were tested. Hedera helix ‘Woerner’ did not exceed in any variation. The treatment with Bacillus subtilis and Bacillus amyloliquefaciens showed both the highest increase in absolute leaf area, also the highest content of dry matter (leaves and shoots). According to the specific root length (m/g), however both showed the smallest value. When the results were statistically analyzed, none relevant differences were explored. New experiments shall be designed with plant physiological stress factors (e.g., water deficit, none or too much fertigation, infections) to force obvious effects.
