Seedlings were raised in a greenhouse in a yellow sand with a soil moisture gradient ranging from -4.5 kPa (above field capacity) to -0.14 kPa (near waterlogged). All fungi enhanced growth of seedlings above that of uninoculated seedlings, but in soils near saturation there was no response to inoculation. Reduced mycorrhizal formation in relation to increasing soil moisture occurred to various degrees for all fungi. This was particularly marked with P. tinctorius. In contrast, L. laccata maintained a relatively high number of mycorrhizal roots at all moisture levels applied, except at the wettest soil treatment. An isolate of D. maculata from a swamp environment did not produce a greater number of mycorrhizal roots at high soil moisture than an isolate of this species from a forest environment. |
