Resumen:
We examined the effects of agronomic management (low, moderate, and high
inputs) and soil properties on arbuscular mycorrhizal fungi (AMF)
community structure collected from the rhizosphere of Capsicum annuum
cultivated in six agroecosystems in Mexico. Chemical and physical soil
parameters differed among agroecosystems. Native communities of
AMF-morphospecies differed between agroecosystems depending on intensity
of agronomic practice. In total 33 AMF-morphospecies were identified
(11genera, and seven families). Soil P availability and pH negatively
affected the distribution and abundance of the AMF species. High input
management resulted in significant modifications in the composition and
structure of the AMF communities. Agroecosystems with high or moderate
input management showed 35% less AMF-morphospecies when compared to low
input management systems. The most diverse AMF community was observed
from agroecosystems with either moderate or low input management.
Funneliformis geosporurn, Claroideoglomus claroideum and C. luteum were
the predominant species observed in this study. High similarity (> 75%)
in the structure of AMF communities among agroecosystems was found,
which suggest that the observed differences between AMF communities from
agroecosystems with high input management compared to that from low and
moderate input management, may be due to changes in species composition.
