En hortensia (Hydrangea macrophylla), el color de las inflorescencias cambia con su desarrollo y efecto diversos factores. esta investigación se determinó dos estados floral (Fresh, Antique), cuatro dosis Al2(SO4)3 pH (4.5, 6.0), en los floretes cultivares hortencia: rosa (TolR) azul (TolA). Se utilizó un clasificador creado redes neuronales artificiales (RNA) como variables entrada modelo RGB ...

Surface vegetation has a substantial impact on soil aggregate stability, which is an important indicator of quality. However, there still limited research the response stability indicators and organic carbon, total nitrogen, phosphorus content in aggregates for different patterns rocky desertification fragile ecological areas. Therefore, order to study effects restoration models related nutrien...

A portion of the Intergenic Spacer (IGS) of the ribosomal RNA operon of 74 isolates of 11 Ar? millaria species from Europe and North America was amplified using the polymerase chain reaction. Amplifications were made from scrapes of living mycelium without DNA extraction. Alu I digests ofthe amplified product were electrophoresed in agarose and stained with ethidium bromide. With few exceptions...

The pink hibiscus mealybug (PHM), Maconellicoccus hirsutus (Green) (Hemiptera: Pseudococcidae) and the associated hymenopterous parasitoid, Anagyrus kamali Moursi, 1948 (Hymenoptera: Encyrtidae), are reported for the first time in Brazil. Specimens of the PHM were collected on nine hosts plants, Annona muricata L. (Anonnaceae), Glycine max (L.) Merr. (Fabaceae), Centrolobium paraensis Tul. (Fab...

The Jaramillo Event was originally defined by Doell and Dalrymple in 1966 on the basis of K^Ar ages from sanidine in the normally, transitionally and reversely magnetized rhyolite domes named Cerro del Abrigo, Cerro Santa Rosa I and Cerro Santa Rosa II, respectively, that erupted following collapse of the archetypal Valles Caldera, New Mexico. We have collected new paleomagnetic data from the t...
