Colonización radical por endófitos fúngicos en Trithrinax campestris (Arecaceae) de ecosistemas semiáridos del centro de Argentina

in arid and semiarid ecosystems, roots frequently form symbiosis with fungi that provides access to nutrients and water. knowledge regarding the study of fungal symbionts colonizing native palms roots is still scarce. we described, quantified and compared fungal colonization in roots of trithrinax campestris from two environmental situations: population with weak-burning-signs and population with strong-burning-signs. t. campestris was colonized by arbuscular-mycorrhizal-fungi (amf) and dark-septate-endophytes (dse). amf colonization was an intermediate type between arum and paris. the amf and dse colonization and root hair production differed between populations. our results suggest that in t. campestris the relation between fungal-symbionts and root-hair-production might be related to tolerance to burning and aridity.
