Abstract:Effects of different fertility regimens on Pisolithus tinctorius (Pt) ectomycorrhizal development on container-grown loblolly pine seedlings were tested in the greenhouse. Vegetative Pt inoculum was mixed into both peat-vermiculite and pine bark growing media before transplanting newly germinated seedlings. A modified nutrient solution (MNS) with various concentrations of N and P was applied to each cell to saturation at 1- and 4-week intervals for 15 weeks; 7 weeks later the study was terminated. Results showed that the production of plantable size seedlings with the best Pt ectomycorrhizal development (>65 percent) in both growing media resulted when MNS containing 250 g/ml N and 60 g/ml P was applied every 4 weeks. This concentration of nutrient solution produced seedlings with needles containing 1.3 percent N and 0.12 percent P, whereas solutions with 400 and 80 g/ml of N and P produced seedlings with needles containing 1.5 percent N and 0.15 percent P and with unsatisfactory Pt development on the roots.
