“…Se colocaron en bolsas de papel, luego fueron secados a la sombra y molidos hasta alcanzar partículas de 1 mm de tamaño. Se seleccionaron los hongos Scleroderma verrucosum y Rhizopogon luteolus por ser hongos que se asocian con el pino (Atala et al, 2012;García et al, 2017b), producen esporas en gran cantidad dentro de sus cuerpos fructíferos o esporocarpos, y son de fácil recolección, almacenado y aplicación en viveros forestales comunales. Madejón et al (2021) recomienda la micorrización de plantas de pino con hongos de la zona, debido a que están adaptados a esas condiciones.…”

Se evaluó el efecto de Scleroderma verrucosum (Vaill) Pers y Rhizopogon luteolus Fr. & Nordh. sobre la calidad morfológica y biológica de plantas de Pinus radiata D. Don en vivero en Vilcashuamán, Ayacucho, Perú. Tratamientos: (1) Micorrización con Scleroderma verrucosum, (2) Micorrización con Rhizopogon luteolus, (3) Mezcla de ambos hongos y (4) Control, en un diseño completamente al azar con 10 repeticiones por tratamiento. Los hongos provinieron de bosques de Pinus radiata y Eucalyptus globulus de la localidad. La inoculación se realizó en el repique a los 30 días de siembra y la evaluación a los 7.5 meses después del repique. Los pinos micorrizados superaron con diferencias significativas al control en todas las variables. En el diámetro del cuello y materia seca de la parte aérea de los inoculados no presentaron diferencias significativas; sin embargo, en altura, materia seca de la raíz y materia seca total destacó el tratamiento Mezcla. En la calidad biológica se observó mayor número de micorrizas en los inoculados, con diferencias significativas frente al control sin micorrizar. Se evidenció mayor porcentaje de micorrizas monopodiales (91%) en relación a los dicotómicos (8.5%) y coraloides (0.6%). Se determinaron relaciones positivas significativas entre las variables morfológicas, pero éstas sobre P. radiata presentaron asociaciones no significativas con el número de micorrizas. El uso individual y en mezcla de hongos ectomicorrízicos silvestres incrementó la calidad morfológica y biológica de P. radiata, por ello se recomienda la aplicación de estos hongos para la producción de plántulas en viveros de Vilcashuamán y otras zonas altoandinas.

“…An important component in plant production is mycorrhizal inoculation through the application of spores of wild ectomycorrhizal fungi (HSECM) (Escobar-Alonso and Rodríguez-Trejo, 2019), which promotes plant-fungus symbiosis. This condition is desirable in species of the genus Pinus in nursery and field to favor plant survival and growth (García-Rodríguez et al, 2017).…”

Substrate and mycorrhization are important aspects when producing plants. The objective of the study was to determine the effect of three substrates inoculated with ectomycorrhizal fungal spores on the morphological characteristics of nursery-grown Pinus durangensis as well as the inherent costs of the substrate. A randomized block experimental design with a 3 x 3 factorial arrangement was used. The substrates evaluated were: 1) peat, vermiculite, and perlite (50:25:25) [PVP]; 2) peat, composted bark, and raw sawdust (50:25:25) [PBS]; and 3) peat and bark (50:50) [PB]. The mycorrhizal inoculants were: 1) Pisolithus tinctorius; 2) Laccaria laccata; and 3) control. The plant was produced in black polyethylene tubes (160 mL) and evaluated at 13 months. The substrate factor presented statistical differences (p ≤ 0.05) in the variables evaluated, with higher values in PVP, followed by PBS and PB, the latter being similar to each other. The mycorrhizal inoculation factor showed differences (p ≤ 0.05) in root and total biomass, Dickson’s quality index, and mycorrhizal colonization, obtaining higher values when P. tinctorius was inoculated, except in the last variable, where the application of L. laccata stood out. In the substrate-mycorrhizal inoculation interaction, the most favorable combination was PVP and P. tinctorius. The PVP substrate was 28.4 and 34.6 % more expensive than PB and PBS, respectively. The combined effect of PVP and P. tinctorius produced the best growth, although the substrate was more expensive.

While atmospheric CO2 concentration ([CO2]) continues to rise, the question of how tree carbon allocation is affected by this change remains. Studies show that carbon assimilation increases under elevated CO2 (eCO2). Yet, no detailed study determined the fate of the surplus carbon, i.e., its compartment and physiological process allocation, nor in multiple species together. In this project we grew 2-year old saplings of four key Mediterranean tree species (the conifers Cupressus sempervirens and Pinus halepensis, and the broadleaf Quercus calliprinos and Ceratonia siliqua) to [CO2] levels of 400 or 700 ppm for 6 months. We measured the allocation of carbon to below- and above-ground growth, respiration, root exudation, storage, and leaf litter. Additionally, we monitored intrinsic water-use efficiency, soil moisture, soil chemistry, and nutrient uptake. Net assimilation, water-use efficiency, and soil nitrogen uptake significantly increased at eCO2 across the four species. Broadleaf species showed soil water savings which were absent in conifers. All other effects were species-specific: Cupressus had higher leaf respiration; Pinus had lower starch in branches and transiently higher exudation rate; and Quercus had higher root respiration. eCO2 did not affect growth, nor litter production. Our results are pivotal to understanding the sensitivity of tree carbon allocation to the change in [CO2] when water is abundant. Species-specific responses should be regarded cautiously when predicting future changes in forest function at a higher CO2 world.
