EFFECTS OF PISOLITHUS TINCTORIUS AND LACCARIA FRATERNA ON THE GROWTH AND MYCORRfflZAL DEVELOPMENT OF PINUSPATULA SEEDLINGS*)
Vegetative 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
in the production of ectomycorrhizas and increase in growth of P. patula seedlings when compared to
uninoculated seedlings. Laccariafraterna inoculated seedlings showed more number of mycorrhizas than 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.
