Response ofLeucaena esculenta to Endomycorrhizae andRhizobium inoculation.

Dual inoculations onLeucaena esculenta plants of eitherGlomus versiforme andRhizobium loti NGR 8 orGlomus sp. andR. loti ENCB 31, gave higher growth and phosphorus accumulation compared with treatments with a single micro-symbiont. The above combinations could be used in a re-forestation programme withL. esculenta in the highlands of Oaxaca State, Mexico. The use of endomycorrhized plants is recommended to alleviate the planting shock-phase, particularly in arid zones, and also the risk of root colonization by possibly less-efficient indigenous fungi.
