Does gibberellin increase the acclimation of seedlings of Alnus acuminata to arsenic?
2020El arsénico es un metaloide que se distribuye naturalmente en la litosfera, sin embargo; factores antropogénicos como la minería aumentan la contaminación en los suelos. El objetivo de esta investigación fue evaluar el efecto de diferentes concentraciones de giberelinas (GA3) en el desarrollo temprano de Alnus acuminata y determinar si este ...

Two Frankia strains were isolated from root nodules of Alnus acuminata collected in the Tucumano-oranense forest, Argentina. Monosporal cultures were obtained by plating a spore suspension of each strain and isolating a single colony. The strains (named AacI and AacIII) showed branched mycelia with polymorphic sporangia and NIR-vesicles.

Herbivore communities on "Alnus acuminata" in relation to different reforestation methods
2013In den Tropen ist die rapide Entwaldung und die daraus resultierende Abnahme der Waldflächen ein hoch aktuelles Thema. Aktive Wiederaufforstung dieser zerstörten Habitate, hat sich als ökologisch und ökonomisch nachhaltige Option erwiesen, die dazu beitragen kann, den negativen Auswirkungen der Entwaldung, allen voran Bodendegradation und Verlust der ...

Holocene changes of Andean alder (Alnus acuminata) in highland Ecuador and Peru
Journal of Quaternary Science, 2004AbstractFossil pollen records from the high Andes of Ecuador and northern Peru show that Alnus increased in abundance at most sites following warming associated with the onset of the Holocene. The peak of Alnus pollen abundance occurred between ∼9000 and 5000 yr BP.

Two new species ofLactariusassociated withAlnus acuminatasubsp.argutain Mexico
Mycologia, 2014In pure stands of Alnus acuminata subsp. arguta trees from Sierra Norte de Puebla (central Mexico) two undescribed ectomycorrhizal species of Lactarius were discovered. Distinction of the two new species is based on morphological characters and supported with phylogenetic analyses of the nuclear ribosomal DNA ITS region and part of the gene that ...

Dry weight loss of litter of Alnus acuminata in the province of Tucumán, Argentina
1994Se estudió la dinámica de descomposición de hojas de Alnus acuminata H.B.K. spp acuminata en tres bosques de esta especie de distintas edades (5-10, 20-25 y 40-45 años) situados en el cerro de San Javier (Tucumán, Rep. Argentina), durante el período abril/'91 a abril/'93, siguiendo la metodología de las "litter bags". Se realizó una regresión entre los

Daños causados por fitopatógenos y entomofauna asociada en alnus acuminata h.b.k
1989Con estudios realizados sobre árboles de aliso, Alnus aeuminata H.B.K. se sugiere que la presencia de Saltahojas (HOM:Cicadellidae) en alta densidad, proporciona un marco propicio para la invasión de hongos fitopatógenos como Gloesporium, Alternaria y posiblemente roya, entre otroslo que conlleva al deterioro gradual de las plantas, debido al efecto ...
