Karyotype analysis of Capsicum pubescens (Solanaceae). Chromosomes are described, compared and illustrated, using a modified orcein staining technique. C. pubescens has a diploid number of 2n = 24 chromosomes, 11 pairs are metacentric and one pair is submetacentric.

Análisis cariotípico de Capsicum pubescens R&P (Solanaceae). Los cromosomas han sido descritos, comparados y dibujados, usando una técnica de coloración modificada, C. pubescens tiene un número cromosómico diploide 2n = 24, de los cuales 11 pares son metacéntricos y 1 par submetacéntrico.

The genetic diversity of three populations designated as ecotypes of golden berry (Physalis peruaviana) is studied using protein quantification and polymorphism of seed storage proteins (SSPs) by denaturating polyacrylamide gel electrophoresis (SDS-PAGE). As well, biochemical characteristics of seed proteins were identified. The populations were from San Pablo province (Agroandino ecotype), Celendín province (Celendino ecotype) and Cajabamba province (Cajabamba ecotype), all from Cajamarca Department. There was not difference among the three populations based on protein quantification. Globulins (82.4%) were the majority fraction followed for albumins (13.9%), glutelins (3.7%) and prolamins (0.7%). Only albumins showed polymorphism, showing 21 proteins between ~6.5 to ~45 kDa and three different electrophoretic profiles, which were share among the three populations. Legumins and vicilin...

Tara (Caesalpinia spinosa) is an Andean legume which has an economic importance for their active substances and derivate products. However, there are not morphometric studies which allow characterizing populations to have genetic material for breeding or conservation programs. In the present study morphometric variables are analyzed to identify agro-morphological characteristics which permit differentiate populations. Ten variables of pod and seed from Yauyos and Ayacucho were analyzed; the comparison of means was evaluated using the Mann-Whitney. To determine the relationship between variables a Spearman correlation analysis between populations and taking in account the whole population was performed. According to these results, linear regression models were implemented. Finally, principal component analysis (PCA) was used to visualize patterns in the data. Of the ten variables studied,...

Chenopodium ambrosioides “paico” es una planta medicinal aromática usada desde tiempos prehispánicos y en la actualidad forma parte de la dieta de pobladores de diferentes regiones del Perú debido al conocimiento acerca de sus propiedades medicinales, y sobretodo antiparasitarias. Sin embargo, no existen reportes acerca de la información del material genético de poblaciones de “paico” que desarrollan en nuestro país. En ese sentido, en el presente estudio, realizamos el análisis citogenético utilizando la técnica del squash con muestras provenientes de tres diferentes regiones del Perú: Ayacucho, Cajamarca y La Libertad, logrando determinar que el número cromosómico fue de 2n=32 para las tres regiones muestreadas.
