| الوصف: | Cover crops production and soil cover in semi-arid ecoregions are considered the most challenging issues for improving soil quality into tropical ecosystems. The AMF diversity, and plant transpiratory rate in 5-year cultivation of green manure plant species in the Brazilian semi-arid, Areia, Paraiba, Brazil was investigated between August 2017 and April 2018. Soil samples containing colonized roots and AMF spores were collected using soil cores. Plant transpiratory rate was determined using an infrared gas analyzer under ten green manure plant species: B. decumbens Stapf. cv. Basilisk, C. ensiformis (L.) DC, C. juncea L, C. ochroleuca G. Don, C. spectabilis Roth, L. purpureus (L) Sweet, M. pruriens (L) DC, and N. wightii (Wight & Arn.) J.A. Lackey. The most abundant AMF species in our experiment were Claroideoglomus claroideum, Claroideoglomus etunicatum, Funneliformis mosseae, Glomus coremioides, and Rhizoglomus intraradices. The highest values of AMF diversity, dominance, and richness were found on the plots where N. wightii were cultivated. For the transpiratory rate, the highest leaf temperature and internal CO2 concentration were found on plots where C. ensiformis was cultivated, while the highest values of water use efficiency and instantaneous water use efficiency were found on plots where C. juncea was cultivated. Our findings suggest that: 1) green manure practice changed AMF abundance, richness, diversity, and dominance in tropical conditions; and 2) the plant transpiratory rate (e.g., water use efficiency, stomatal conductance, internal CO2 concentration, and photosynthetic rate) was promoted by plant species from Fabaceae family. The results highlight the importance to consider plant species from Fabaceae family as hosts for AMF species, based on a sustainable way to improve soil biodiversity, ecological processes, plant physiology, and soil productivity. |
