Abstract
The effect of different inoculation amounts of Pisolithus tinctorius (Pt) spores and fertilizers on the growth of Pinus densiflora seedlings grown in fumigated or nonfumigated soils were tested in the: polyethylene pots. To infest the pot soil with Pt spores, the mixture of the spores with sterilized nursery soil was used after seeding. Eighteen months after inoculation, mycorrhizal formation was 42-70% in fumigated plus Korean-Pt inoculated pots, 60-70% in fumigated plus U.S.-Pt inoculated pots, and less than 1% in non-fumigated, Korean-Pt inoculated pots. Growth enhancement effect of Pt spore inoculation was shown on only fumigated soil and the inoculation increased the seedlings height (8-38%), stem diameter (9-40%) and dry weight (6-73%). Especially 0.4g per pot application rate increased the height (30-31%), stem diameter (23-28%) and dry weight (56-69%), while the 0.2g U.S. Pt spore per pot rate increased 26-38, 17-20 and 58-60%, for height, stem diameter, and dry weight respectively. At 1X fertilizer application rate (urea 2g, fused superphoshate 4g, and potassium chloride 1g per pot), the 0.4g per pot rate resulted in more dry weight by 18% than that at 1/2X rate. The result indicated that there is a need for further research on inoculating nonfumigated soil with Pt and that appropriate application rates of fertilizers and Pt spores are 1X and 0.2-0.4g per pot on fumigated soil, respectively.
