El estudio tuvo por objetivo evaluar el efecto de cinco consorcios micorrícicos arbusculares en el crecimiento de quina (Cinchona sp.) en vivero en Amazonas. Se instaló en un Diseño Completamente al Azar (DCA) con seis tratamientos, cinco consorcios micorrízicos y un testigo, tres repeticiones y nueve unidades experimentales. Los consorcios fueron colectados de la rizósfera de plantas de quina en cuatro provincias y cinco distritos: Rodríguez de Mendoza (San Nicolás), Chachapoyas (Leymebamba), Bongará (Yambrasbamba), Luya (San Jerónimo y Conila) de la región Amazonas, éstos fueron multiplicados con Zea mays como hospedero durante 80 días, luego se inoculó a las plántulas de quina con 50 g de sustrato de HMA. Los resultados muestran que existe efecto positivo de los consorcios micorrízicos arbusculares en plantones de quina, sobresaliendo los tratamientos T4 (CM-SJ), y T2 (...

El estudio tuvo por objetivo evaluar el efecto de micorrizas arbusculares y abonos orgánicos en el comportamiento vegetativo de Cinchona officinalis en ambientes controlados. La investigación se instaló bajo un diseño completo al azar con arreglo trifactorial (4A: micorrizas x 3B: abonos x 2C: ambientes), contando con 72 unidades experimentales. Las plantas de quina fueron inoculadas en vivero e invernadero con 40 g de micorrizas procedentes de bosques naturales (San Jerónimo, Conila y Leymebamba) y abonadas con 40 g de gallinaza y humus de lombriz. Se encontró que la mortalidad de la quina se dio en el vivero y abonadas con gallinaza, con un 6.3 % en promedio, por su parte, no se reportó mortalidad a nivel de invernadero; respecto a la velocidad de crecimiento, los consorcios micorrízicos SJ y LEY tuvieron mayor efecto, juntamente con la aplicación de humus de lombriz a nivel...

Cinchona officinalis, commonly called cascarilla or quina, has medicinal value; and is on Peru’s national coat of arms representing its plant wealth (flora), however, it is threatened by anthropogenic activities. This study aimed to determine the effect of the commercial product Myco Grow® on the growth of C. officinalis in nursery. A randomized design was used with two treatments, one with Myco Grow® application (WM) and the other without incorporating this commercial product (NM). Each treatment had three replicates consisting of 30 plants each. Monthly evaluations were performed, during which the number of dead plants, plant height, and plant diameter were recorded. Additionally, at the end of the study, the anhydrous weight of leaves, stems, and roots; leaf area; mycorrhizal frequency; mycorrhizal colonization index; and the length of extra-radicular mycelia were determined. The ...
