Mycorrhizal response of halophytes to plant growth in non-saline soil conditions

摘要

A glycophyte species and three different halophytes species were examined for colonization and growth response to arbuscular mycorrhizal (AM) fungi under non-saline soil conditions. Roots of Trifolium alexanderium as a glycophyte and AM responsive plant highly colonized (more than 85%) and plant growth increased significantly by inoculation with AM fungi. A low level of AM colonization (less than 5%) was found in the roots of Haloxylon persicum, Seidlitzia rosmarinus and Salsola sp as halophytes. Despite low level colonization, AM fungi inoculation increased plant growth of two halophytes species (Haloxylon persicum and Seidlitzia rosmarinus). The present study demonstrates that although roots of halophytes have intrinsically low symbiosis with AM fungi, but, even at low level of AM colonization, they show positive growth response to AM fungi inoculation in non-saline soil conditions.
