[Arbuscular mycorrhizae in Paris polyphylla var. yunnanensis].
OBJECTIVE
To study the infection situation of arbuscular mycorrhizal fungi, as well as the mycorrhizal structures of Paris polyphylla var. yunnanensis, and the main types and quantities of AMF spores in rhizosphere soil.


METHODS
The arbuscular mycorrhizal of P. polyphylla var. yunnanensis were detected by Phillips and Hayman staining. At the same time, some AMF spores were accessed by Gendemann's Wet-screening method and identified by their morphological characteristics.


RESULTS
Arbuscular mycorrhizal fungi could infect the roots of P. polyphylla var. yunnanensis and formed arbuscular mycorrhizal. Infection rate was from 35.3% to 98.6%, indicating that infection strength was strong. From 10 soil samples collected in Yunnan, 11 Acaulospor species, 7 Glomus species, 3 Gigaspora species and 3 Scutellospora species were isolated and identified, including Acaulospora appendicola, A. brieticulata, A. excavata, A. foveata, A. lacunosa, A. laevis, A. koskei, A. myriocarpa, A. polonica, A. rehmii, A. scrobiculata, Glomus albidum, G. ambisporum, G. deserticola, G. fragarioides, G. luteum, G. microaggregatum, G. multiforum, Gigaspora albida, G. margarita, G. ramisporophora, Scutellospora calospora, S. pellucida and S. gilmorei. Among them, Acaulospora brieticulata was advantage species.


CONCLUSIONS
AMF may be a potent biological resource which can stimulate the growth of P. polyphylla var. yunnanensis.
