Respuesta a la inoculación de hongos micorrízicos arbusculares en diferentes líneas de trigo (Triticum durum L.) de primavera.

With the aim to evaluate the response to arbuscular mycorrhizal fungi inoculation in different lines of spring wheat this research was developed under controlled conditions. Seeds from five spring wheat (Triticum durum L.) lines (AW-774, AC Carberry, HY-162, Major and AAC Scotia), with 98 % germination, were used and disinfected before sowing. The INCAM-4 strain: Glomus cubense (in solid and liquid formulation), the Canadian commercial inoculant MYKE®PRO (Rhizoglomus irregulare) and a control without inoculation were used. Treatments were distributed with an arrangement of divided plots under a completely randomized design, the main plot being the inoculation of AMF and the five lines of spring wheat as sub-plot. The evaluations were carried out at 120 days after sowing and variables related to mycorrhizal functioning (frequency and intensity of colonization), with the growth and development of the plants and the crop yield were determined. The results showed a positive effect of Glomus cubense inoculation in both formulations (solid and liquid). A differential response in AMF inoculation was observed among spring wheat lines. The Major and AW-774 lines showed significant increases in the variables studied compared to the rest. [ABSTRACT FROM AUTHOR]
