Arbuscular mycorrhizal fungi (AMF) colonize land plants in almost every ecosystem, even in extreme conditions, such as saline soils. In the present work, we report the mycorrhizal capacity of rhizosphere soils collected in the dry desert region of the Minqin Oasis, located in the northwest of China (Gansu province), which is characterized by several halophytes. Lycium spp. and Peganum nigellastrum were used as trap plants in a greenhouse experiment to identify autochthonous AMF associated with the halophytes’ rhizospheres. Morphological observations showed the typical AMF structures inside roots. Twenty-six molecularly distinct AMF taxa were recovered from soil and root DNA. The taxonomical diversity mirrors the several AMF adapted to extreme environmental conditions, such as the saline soil of central China. Knowledge of the AMF associated with halophytes may contribute to select specific fungal isolates to set up agriculture strategies for protecting non-halophyte crop plants in saline soils.

Mycorrhizal Inoculation

This study was conducted to assess the influence of gibberellic acid (GA3) and arbuscular mycorrhizal fungi (AMF) on the flowering and quality of Zantedeschia albomaculata (Hook.) Baill ‘Albomaculata’ plants. Before planting, the rhizomes were soaked in water or an aqueous solution of GA3 at a concentration of 150 mg dm−3 for 30 min. A mixture of AMF was applied to the rhizomes a week after planting. The AMF treatment increased the yield of inflorescences of the ‘Albomaculata’ cultivar by 100%. AMF and GA3 had a favourable effect on the quality of inflorescences, expressed by the length of peduncles, whereas AMF individually positively affected the length of the spathes. AMF and GA3 had no effect on the level of macroelements in calla lily leaves, with the exception of calcium (Ca). The leaves of mycorrhized plants had a high content of sodium (Na) and micronutrients, except for iron (Fe). The results of the study showed that GA3 could be replaced by mycorrhizal inoculation when applied to Zantedeschia plants.

Lettuce plants were grown in the foil tunnel in pots filled with peat substrate. The experimental factors were: concentration of phosphorus in the substrate (70 or 140 mg dm-3), inoculation of substrate with arbuscular mycorrhizal fungi (+AMF or –AMF) and concentration of selenium in the substrate (0, 6 or 12 mg dm-3). Mycorrhizal frequency in roots was affected by concentration of P, inoculation with AMF and interaction between these factors. Higher mycorrhizal frequency was found in plants inoculated with AMF and grown under conditions of lower P concentration. AMF did not affect an accumulation of Se in leaves. However, higher concentration of P and Se in the substrate affected Se concentration in leaves. The average yield of lettuce decreased with increasing level of Se in the substrate. The presence of Se in the substrate led to decrease of K, Mg, Fe, Cu and Mn content of plants. AMF did not have an effect on the content of sugars in leaves.

Summary: Arbuscular fungi (Glomeromycota) in the rhizosphere of Atriplex lampa at two saline environments of Córdoba (Argentina): depth influence on root colonization and the presence of morphospecies. Atriplex lampa is a valuable fodder shrub available for browsing by livestock even during drought periods in the Chaco Phytogeographical Province. Halophytes may benefit from the association with arbuscular mycorrhizal fungi (AMF) through improved tolerance to drought and salt. Ecological studies of AMF are generally restricted to the main rooting zone. However, AMF vertical distribution and seasonal dynamics in natural saline soils of Argentina have been poorly studied. The aim of this work was to explore AMF root colonization, root concentration and to identify AMF morphoespecies in A. lampa rhizosphere in two saline environments (Salinas de Ambargasta and Salinas Grandes) of central Argentina, in five soil depth levels, during the wet and dry seasons. Despite we did not find arbuscules, AMF were found colonizing A. lampa roots in all depth levels. Salinas Grandes showed the highest root colonization value, and showed the highest root concentration, during wet season. The 20 AMF morphospecies identified in this work belonged to the genera: Acaulospora, Ambispora, Claroideoglomus, Diversispora, Funneliformis, Glomus, Septoglomus and Scutellospora. This is the second record in Argentina of AMF structures in A. lampa roots. Future studies that evaluate mycorrhizal dependency of the plant are necessary to confirm the function of the symbiosis.Key words: Arbuscular mycorrhizal fungi; saline soils; Atriplex lampa; depth soil; seasonality.Resumen: Atriplex lampa es un arbusto halófito de la provincia fitogeográfica Chaqueña que constituye un recurso forrajero a lo largo de todo el año. Las plantas halófitas se pueden beneficiar al asociarse con los hongos micorrícico arbusculares (HMA), ya que le proveen resistencia contra la salinidad y la sequía. En general, los estudios acerca de los HMA están restringidos a los primeros centímetros del suelo y existe poca información sobre su presencia a mayores profundidades. El objetivo de este trabajo fue estudiar la colonización, la concentración radical e identificar las morfoespecies de HMA en la rizosfera de A. lampa en dos ambientes salinos del norte de la provincia de Córdoba, durante dos estaciones del año, y en cinco profundidades del suelo. Aunque no se encontraron arbúsculos, A. lampa presentó colonización radical por HMA en todas las profundidades. El mayor valor de colonización micorrícica y de concentración radical se observó en las Salinas Grandes. Se identificaron 20 morfoespecies de HMA pertenecientes a los géneros: Acaulospora, Ambispora, Claroideoglomus, Diversispora, Funneliformis, Glomus, Septoglomus y Scutellospora.Este es el segundo registro en Argentina de la presencia de HMA en raíces de A. lampa. Es necesario realizar estudios que evalúen la respuesta de A. lampa frente a la inoculación con HMA para confirmar la funcionalidad de la simbiosis.Palabras clave: Hongos micorrícico arbusculares; suelos salinos; Atriplex lampa; profundidad del suelo, estacionalidad.
