Abstracts |
A field experiment was carried out to compare the
effectiveness of inoculation with three arbuscular mycorrhizal
(AM) fungi, namely Glomus intraradices Schenck & Smith, Glomus
deserticola (Trappe, Bloss. & Menge) and Glomus mosseae (Nicol &
Gerd.) Gerd. & Trappe, and the addition of Aspergillus
niger-treated dry olive cake (DOC) in the presence of rock
phosphate, in increasing root nitrate reductase (NR) and acid
phosphatase activities, mycorrhizal colonization, plant growth
and nutrient uptake in Dorycnium pentaphyllum L. seedlings
afforested in a semiarid degraded soil. Three months after
planting, both the addition of fermented DOC and the mycorrhizal
inoculation treatments had increased root NR activity
significantly, particularly the inoculation with G. deserticola
(by 75 percent with respect to non-inoculated plants), but they
had no effect on root acid phosphatase. Mycorrhizal inoculation
treatments with G. deserticola or G. mosseae on their own were
even more effective than the addition of fermented DOC alone in
improving the growth and (NPK) foliar nutrients of D.
pentaphyllum plants. The combined treatment involving the
application of microbially-treated agrowastes and mycorrhizal
inoculation with AM fungi, particularly with G. mosseae, can be
proposed as a successful revegetation strategy for D.
pentaphyllum in P-deficient soils under semiarid Mediterranean
conditions
