The application of endophytic bacteria to improve stability and vitality of poplar plants to increase biomass generation in fast growth plantations (Endophyten II)

Endophytic bacteria may act as plant growth promoters by synthesising phytohormones or enzymes, fixing athmospheric nitrogen or controlling plant diseases.

Background and Objective

The aim of this is to test the beneficial effects of endophytic bacteria with respect to the influence on the growth of poplars for sustainable biomass production.In addition bioprparates of these bacteria as an easy practical application will be developed and tested.


Endophytic bacteria will be isolated from poplars and afterwards tested with different systems on poplar plants.
