Abstract:

Endophytes are bacteria present in plants that form a symbiotic relationship with
their hosts and may promote plant growth and health (Ryan et al., 2008). We extracted
Pseudomonas endophytes from Miscanthus × giganteus; a series of strains were selected
for application to two oilseed rape (OSR) trials. Endophytes colonise plants (including
the root-surface) and allow the plant to utilise nutrients present in the rhizosphere. This
potentially provides a yield boost for colonised plants, allowing for efficient fertiliser
strategies and improved yield performance (Redondo-Nieto et al., 2013). This study has
provided evidence that the application of specialised live microbial biofertilisers can
enhance aspects of crop development when applied in the field. The results show that
there was a significant increase in crop stem and leaf of “Compass” a variety of Oilseed
rape. The results did not indicate that there was a significant increase within the overall
yield of the crop.
