Fungal Inoculation Of Western White Pine Trees

July 15, 2019

Fungal inoculations in western white pine may improve tree defense against disease

As part of our ongoing research on western white pine and their fungal symbionts, we spent last winter preparing candidate fungi to inoculate >500 western white pine (WWP) seedling

Working in collaboration with the Dorena Genetic Resource Center (DGRC) in Eugene, Oregon, we continue to investigate the role of fungi in mitigating disease in western white pine trees.

Suillus species are known symbionts of white pines and have been shown to increase both biomass and nitrogen content of trees (Jenkins et al., 2018).

Dozens of Suillus mushroom caps were collected and taken to the lab where they were placed on foil at room temperature and left overnight

Using multiple different methods, we also tested over 70 foliar fungal endophytes found in needles of healthy white pines, for the inhibition of pathogen growth in the lab

Suillus spores diluted in water were pipetted directly onto roots of western white pine seedlings.

We will then compare survival and defensive chemistry of those seedlings inoculated with fungal treatments to seedlings that received no fungal inoculations to determine how fungi influence disease outcome in western white pine.
