Abstract

Substantial yield losses of Styrian oil pumpkin caused by the fungus Didymella bryoniae and bacterial pathogens were recently reported. Here we applied bacterial endophytes with a broad antagonistic activity to pumpkin plants by seed priming. Effects of the bacterial inoculants with and without chemical seed treatments on plant growth and health were evaluated during three different field trials in two consecutive years (2010 and 2011). Biological seed treatments strongly supported the germination of pumpkin seeds. In 2010, the germination of the biologically treated seeds was comparable to the rate following a chemical treatment; whilst in 2011 effects of biological seed treatments were more obvious, including an increased emergence rate up to 109 % by Serratia plymuthica S13. Furthermore, tolerance against desiccation stress was observed for Serratia as well as for Lysobacter gummosus L101 …
