Abstract

Abstract: To increase the rooting rate and improve the quality of adventitious root system, mycorrhization of nematode-cultured plantlets of nematode-resistant Pinus densiflora was studies. Three inoculation methods were compared. The results showed that there was no significant effect on rooting rate after inoculating ectomycorrhizal fungi with different methods at the root elongation stage, but the survival rate was affected significantly. To some extent, inoculation of mycorrhizal fungi could improve the survival of tissue-cultured plantlets. Significant difference has been obsererved at the degree of mycorrhization and morphological characteristics after inoculating with Rhizopogen luteous(Rl), Pisolithus tinctorius(Pt2)and Boletus edulis(Be). Pt2 was the most compatible ectomycorrhizal partner for P. densiflora. The survival rate of plantlets inoculated with Pt2 was higher than those inoculated with Rl and Be.
