“…in our findings, inoculation of the two strains improved the chlorophyll content of hazelnut seedlings as compared with uninoculated seedlings. The increase in levels of chlorophyll content in fungus treated seedlings has been reported due to the direct consequence of symbiotic association which led to a higher uptake of water and nutrients resulting in higher biosynthesis (Dutt et al 2013). The same as Ahangar et al (2012), in our research findings in spite of the root colonization, the growth, physiological parameters and nutrient uptake in hazelnut seedlings inoculated with T. harzianum were lower than those with G. intraradices, but the inoculated seedlings showed an increase in growth and physiological characteristics compared to the control.…”

(2017): Biomass allocation, leaf gas exchange and nutrient uptake of hazelnut seedlings in response to Trichoderma harzianum and Glomus intraradices inoculation. J. for. sci., 63: 219-226.Mycorrhizal fungi form mutualistic symbioses with the roots of 80% of plants which increase growth and nutrient uptake for the host plants. This research was conducted to determine the effect of individual Glomus intraradices schenck & smith and Trichoderma harzianum rifai species on the root colonization, biomass allocation, physiological characteristics and nutrient uptake of hazelnut (Corylus avellana linnaeus) seedlings in the nursery. The results showed that both G. intraradices and T. harzianum improved biomass, physiological characteristics and nutrient uptake of hazelnut seedlings as well as simultaneous root colonization. However, the growth rate for G. intraradices treatment was significantly higher than that for T. harzianum treatment. The highest leaf dry mass (2.66 g), root dry mass (3.39 g), root volume (11.31 cm 3 ), total plant dry weight (11.20 g) were detected in seedlings inoculated with G. intraradices. inoculation with G. intraradices and T. harzianum increased net photosynthesis (64 and 26%), stomatal conductance (66.1 and 31.4%) and water use efficiency (50 and 22%). Both G. intraradices and T. harzianum showed increased nutrient accumulation. The G. intraradices treatment resulted in the most efficient nutrient absorption with increases of 58.4% (n), 85.2% (P) and 83.2% (K) in plants. it can be deduced that although G. intraradices in comparison with T. harzianum more favourably affected the growth and leaf gas exchange as well as nutrient uptake of hazelnut seedlings, it can be suggested that the inoculation of hazelnut roots with both arbuscular mycorrhizal fungi is a proper measure to produce the healthy and strong seedlings of this species in the nursery.

“…RDA01, NICS01, and DFC01 on sesame seedling growth The fungi isolated from the rhizosphere soil promote plant growth, and could be used as biocontrol agents, but amino acid changes during the fungal interaction have rarely been studied. Several reports have suggested that plant growth is enhanced by the application of soil fungi (Ruanpanun et al 2010;Tchameni et al 2011;Dutt et al 2013). In the present study, three soil fungal isolates, Penicillium spp.…”

This study investigated the plant growth promotion and stress mitigation effects of Penicillium species RDA01, NICS01, and DFC01 on sesame (Sesamum indicum L.) plants. The fungal isolates NICS01 and DFC01 significantly enhanced shoot length, root length, and fresh and dry seedling weight, due to the secretion of various concentrations of amino acids (Asp, Thr, Ser, Asn, Glu, Gly, Ala, Val, Met, Ile, Leu, Tyr, Phe, Lys, His, Try, and Arg). Penicillium sp. NICS01 increased the amount of chlorophylls, proteins, amino acids, and lignans in the sesame plants more so than in controls. Sesame plant growth was stunted by high soil salinity, and application of the three fungal isolates increased plant survival. The RDA01 and NICS01 strains significantly increased shoot length and fresh and dry seedling weights under salt stress conditions. In addition, an in vitro study of the Penicillium spp. revealed their antagonistic activity toward the pathogenic fungi Fusarium spp. Fusarium spp. reduce shoot length; co-inoculation with the NICS01 or DFC01 isolates significantly increased shoot length in infected plants. Our results suggest that exogenous application of the Penicillium sp. NICS01 can act as a biofertilizer and a biocontrol agent to improve plant growth and enhance plant survival against salt stress and Fusarium infection.

“…En este caso, las interacciones entre la inoculación micorrízica y la adición de fertilizante fosfatado mostraron efectos distintos. Por ejemplo, el tratamiento P. sintillans más 20 ppm de P, incrementó las variables de crecimiento más que los tratamientos de manera individual, resultados similares ha sido reportados por (Dutt et al, 2013). En este sentido, la adición de P. scintillans podría hacer más eficiente el uso de fertilizante y representar un avance en la reducción de las dosis actuales de fertilizante utilizadas para el cultivo de aguacate.…”

ResumenLos hongos micorrízicos arbusculares (HMA) son una alternativa biológica para aumentar la absorción del fósforo y reducir el uso excesivo de fertilizantes fosfatados. El objetivo de este trabajo fue evaluar el efecto de diferentes concentraciones de fertilización fosforada en plantas de aguacate con y sin micorriza. Para el experimento se utilizó un diseño factorial con dos factores: inoculante micorrízico (con tres niveles: Rizofermic-UV, Pacispora scintillans y sin inocular) y fertilización con fósforo (con cinco niveles: sin fertilizante, 20, 40, 80 y 160 ppm; utilizando H2PO4 como fuente de fertilizante), cada tratamiento con cuatro repeticiones. A 401 días después de la inoculación se evaluó altura, diámetro, numero de hojas, área foliar, tasa de crecimiento, peso fresco y seco y porcentaje de colonización micorrízica. Las variables se analizaron con una prueba de Fisher, considerando significativo un valor de p< 0.05. El tratamiento con 160 ppm causó la muerte de las plantas a los 150 días, mientras que plántulas inoculadas más 20 ppm mostraron un incremento en variables de crecimiento significativo (p< 0.05) con respecto al testigo. Tanto plantas inoculadas con Rizofermic-UV como con P. scintillans AbstractThe arbuscular mycorrhizal fungi (HMA) are a biological alternative to increase the absorption of phosphorus and reduce the excessive use of phosphate fertilizers. The objective of this work was to evaluate the effect of different concentrations of phosphorus fertilization on avocado plants with and without mycorrhiza. A factorial design was used with two factors: mycorrhizal inoculant (with three levels: Rizofermic-UV, Pacispora scintillans and uninoculated) and fertilization with phosphorus (with five levels: without fertilizer, 20, 40, 80 and 160 ppm; using H2PO4 as fertilizer source), each treatment with four replicates. 401 days after inoculation, height, diameter, number of leaves, leaf area, growth rate, fresh and dry weight and percentage of mycorrhizal colonization were evaluated. Variables were analyzed using a Fisher's test, with a significance level of p< 0.05. being considered significant. The treatment with 160 ppm caused the death of the plants at 150 days, while inoculated seedlings plus 20 ppm showed an increase in significant growth variables (p< 0.05) with respect to the control.
