e1“mycelial inoculum of P. tinctorius completely colonized roots of loblolly pine seedlings during an 8 mo growth period, formed ectomycorrhizae on approximately 92 percent of short roots, and stimulated twice as much dry matter production as in seedlings ectomycorrhizal with naturally occurring fungi”

Other claims from this paper (6)
- Observation Mycelial inoculum of P. tinctorius completely colonized the roots of loblolly pine seedlings during an 8-month growth period in all soil temperature regimes.
- Observation Mycelial inoculum of P. tinctorius formed ectomycorrhizae on approximately 92 percent of short roots of loblolly pine seedlings.
- Observation When basidiospores of P. tinctorius were added around 2-month-old seedlings already ectomycorrhizal with naturally occurring fungi, approximately half the ectomycorrhizae after 8 months were formed by P. tinctorius.
- Observation Basidiocarps of P. tinctorius were produced around certain microplots.
- Observation The following year, P. tinctorius from overwintered inoculum formed ectomycorrhizae on loblolly pine seedlings when soil was mixed at ratios as great as 1:10 with recently fumigated soil.
- Recommendation Vegetative mycelial and basidiospore inocula of P. tinctorius can be used to artificially infest fumigated soil to produce pine seedlings with ectomycorrhizae.
