EFFECTS OF PISOLITHUS TINCTORIUS AND LACCARIA FRATERNA ON THE GROWTH AND MYCORRfflZAL DEVELOPMENT OF PINUSPATULA SEEDLINGS*)
AbstractVegetative inoculum of Pisolithus tinctorius and Laccariafraterna were inoculated to Pinuspatula seedlings grown in both steam sterilized and unsterilized shola soil. After 4 months of seedling growth, 10 seedlings from each treatment were harvested and various growth parameters were studied. Inoculation of these two fungi resulted inÂ theÂ productionÂ ofÂ ectomycorrhizasÂ andÂ increaseÂ inÂ growthÂ ofÂ P.Â patulaÂ seedlings whenÂ comparedÂ to uninoculatedÂ seedlings.Â LaccariafraternaÂ inoculatedÂ seedlingsÂ showedÂ moreÂ numberÂ of mycorrhizasÂ thanÂ P. tinctorius inoculated seedlings at the end of one year. Both these fungi poorly colonized the root system in both soil treatments. There was no significant difference between these two fungi in improving the seedling growth in the nursery.Key words: Pisolithus tinctorius/Laccaria fraterna/Pinus patula/Inoculum/Seedlings/Growth.
