Hongos micorrízicos de plantaciones de (melina) y su potencial como biofertilizantes en plántulas a nivel de vivero. Año 2015

This research was conducted at the field level 2 Roxb tree plantations G. arbórea. 1 and 3 years old, located in the hinterland of the UTEQ. Studies in the laboratory and nursery were conducted at the Laboratory of Environmental Microbiology and Plant UTEQ, located in the Campus Make Ing Manuel Alvares, located at Km 1.5 of the Quevedo route - Quito; in order to evaluate HMA tree plantations G. arbórea to be identified, quantified and meet production costs to be used as biofertilizer potential level nursery seedlings. For the fieldwork and laboratory research instrument used descriptive statistics, using tree plantations G. arbórea 1 and 3 years old. At the field level to the total population considered for the sample and 1 kg of substrate in each of the plantations established to be identified and quantified in the laboratory area. The results showed a percentage of mycorrhizal colonization of roots planted melina 1 year of age (1.9%) followed by 3 years of age (1.7%) respectively. For plantations of 1 and 3 years of age was obtained, pH in water (H2O) and potassium chloride (KCl), with a range of modern and slightly acidic acid (6.23 and 6.45); (5.22 and 5.25), respectively. They were identified and quantified per 100 grams of moist (gsh -1) G. arbórea from plantations, genera Glomus HMA and Gigaspora, but more spores occurred in 1 year, with 45 espors, followed by 3 years of age, with respectively 33 and 29 spores. Production costs include estimated at HMA in melina seedlings nursery level, they had a benefit / cost ratio of 1.19 and a yield of 18.54%.
