“…The hyphae of the fungus have a smaller diameter and greater extension (Bolan, 1991) and can be in places in the soil that absorbent hairs cannot reach (Johansen et al, 1993), facilitating the uptake of slowly diffusing nutrients such as phosphorus (Sieverding, 1991;Jakobsen et al, 1992). Arbuscular mycorrhizal fungus not only improve the nutrition of T. alata, but they can also help the plant tolerate water stress (Brundrett, 2009), and better resist attack by soil-borne pathogens (Sierra-Escobar et al, 2017). All these advantages make T. alata improve its invasive capacity.…”

Background and Aims: Thunbergia alata is one of the ten most problematic invasive plant species in Colombia. Its rapid colonization and adaptation to Andean forests have affected the composition and structure of indigenous plant communities. In this research, analysis of functional traits was carried out, generating new information that could explain the rapid colonization, adaptation and invasive potential of T. alata in this type of Andean environment. Methods: To obtain this information, a series of observations were made on the morphology and anatomy of roots, stems, leaves, flowers, fruits and seeds. Likewise, a characterization of its floral visitors and symbiotic relationships with soil microorganisms was carried out. Key results: We determined that both morphological traits and interaction phenomena favour the adaptability of T. alata in Andean forests and could contribute to a greater extent to its active colonization in this type of environment. An active association of T. alata was found with different species of native and introduced floral visitors, with a total of 2266 floral visits made during our study by seven species of insects belonging to the orders Coleoptera and Hymenoptera. Mycorrhizal fungal spores associated with T. alata populations were found at all sampling sites. The number of spores per 100 g of soil varied between 300 and 424. All the roots of T. alata, without exception, had high colonization by arbuscular mycorrhizal fungi. Conclusions: We believe that the information obtained in this research will contribute to the generation of comprehensive and effective strategies for the control of this species in Andean forests.

An experimental greenhouse campaign was conducted to evaluate the effect of arbuscular mycorrhizal fungi (AMF) on the production of essential oils in rosemary (Rosmarinus officinalis L.). For effect, a completely randomized experimental design was implemented, with three treatments composed of soil plus multisporic inoculum (Glomus spp, Acaulospora spp, Entrophosfora spp, Scutellospora spp.), soil plus monosporic inoculum (Entrophosfora colombiana), and the control treatment without inoculation, all of these with ten replicates per treatment. The soil used for all experimental units was sterilized and adjusted to 0.02 mg L-1 of P (phosphorus), the optimum concentration for the mycorrhizal condition. The response variables were: foliar P content, aerial dry mass, mycorrhizal colonization, and essential oil yield. The results of aerial dry mass indicate significant increases in the inoculated treatments compared to the control treatment. Leaf P showed no differences between treatments. The average mycorrhizal colonization of the inoculated treatments was 73%. As for the essential oils produced by the rosemary plants, the results were the inverse of those of the mass, where a higher yield was found in the control treatment. According to the data, the use of HFMA in the production of rosemary favors the development of the plant; on the other hand, the yield of essential oils could be compensated by the higher biomass produced, which would allow producers to increase the amount of oil extracted. Keywords: essential oils, arbuscular mycorrhizal fungi, Rosmarinus officinalis.
