Talk Description

Endophytes, bacteria and fungi that live within plants, have recently been found to supply hosts with nutrients and pathogen-resistance, which increases yield in plants living under poor conditions. As such, Intrinsyx Bio has developed an easy-application treatment of beneficial endophytes ("Apollo beads"), designed specifically for commercially grown poplar trees. The apollo beads were applied to hybrid poplars growing in the Willamette valley to see what effect they had on growth in a field setting. If successful, endophyte treatments could decrease fertilizer needs and environmental impact of commercially grown poplar while increasing yield and drought resistance. Our trial yielded no change in average biomass within the first year, but this may have been due to uncontrolled variables.
