Abstract

These experiments were conducted for three seasons (1994-1997), with the objective of determining the performance of 15 AMF strains on coffee seedling development in three of the main types of coffee-growing soils from Guamuhaya mountainous lands: lixiviated Red Ferralitic, lixiviated Red Fersialitic and Gleyed Brown soils. A randomized block design with 16 treatments and three replicates was used, besides evaluating stem height, stem diameter, leaf pair number, leaf area, plant top, root and total dry weights seven months after seeding; also, mycorrhizal colonization percentage was determined. Data were processed according to multivariate
procedure of main components and cluster analysis; the former
showed a single component formation, it accounting for about
85 % of the original variation recorded in every soil studied
whereas the latter collected strains according to their behavior
in different soils, it proving that their general performance is
not affected by years. Differences were recorded on AMF
strain effectiveness per type of soil, it generally increasing
leaf area efficiency indexes as their fertility levels decreased.
The highest values (72.20, 68.15 and 67.15 %) were achieved
by Glomus manihotis, Glomus intraradices and Acaulospora
scrobiculata on the lixiviated Red Ferralitic soil, which was among the least fertile soils studied; concerning lixiviated Red
Fersialitic soils, Glomus fasciculatum and two ecotypes from
Glomus mosseae strains had notable values ranging between
65.10 and 66.80 % whereas in the Gleyed Brown soil, the best
strains were Glomus intraradices, another ecotype of Glomys
mosseae (T5) and Glomus fasciculatum with effective records
of 52.20 to 54.86 %.
