Abstract: The arbuscular mycorrhizal status of 65 plant species growing in the dryhot valley of Jinsha River (Binchuan and Yongsheng Counties) was surveyed by means of acid stain after the roots were lysised in alkaline solution.It was found that plants growing in different areas of the dryhot valley of Jinsha River shown a different arbuscular mycorrhizal fungal infection and infection intensity.Most of common plant species growing in the dryhot valley of Jinsha River usually formed arbuscular mycorrhizae.The arbuscular mycorrhizal status of a definite plant species in different parts of the river may be relative to its mycorrhizal dependency.
