Pitahaya (Hylocereus spp.) is an economically significant cactus fruit in Peru, renowned for its rich nutritional profile and antioxidant properties while exhibiting wide biological diversity. This study aimed to morphologically characterize seven pitahaya accessions using qualitative and quantitative descriptors related to the cladodes, flowers, and fruits. Univariate and multivariate (FAMD, PCA, MCA, and clustering) analyses were employed to identify and classify the accessions based on their morphological traits. The analyses revealed three distinct groups: one consisting solely of AC.07; another with AC.02, AC.04, and AC.06; and a third including AC.01, AC.03, and AC.05. The first group exhibited superior characteristics, particularly in fruit traits such as the stigma lobe count (23.3), number of bracts (26.5 mm), and length of apical bracts (15.75 mm). The second group recorded the...

La pitahaya amarilla (Hylocerus megalanthus) es un cultivo reciente que empieza a tener un gran potencial en el país por su alto valor nutricional y su demanda en el marcado nacional e internacional, para ello, es importante proporcionar una nutrición adecuada al cultivo. El objetivo de la presente investigación fue evaluar el efecto del potasio y giberelinas sobre el rendimiento y calidad de frutos de pitahaya amarilla (H. megalanthus). Los factores estudiados consistieron en 3 dosis de potasio y una dosis de giberelina más un testigo, combinados en un arreglo factorial (4x2), haciendo un total de 8 tratamientos, distribuidos en un DBCA con 5 repeticiones, en plantas homogéneas de 3 años de edad. Como resultado se obtuvo que el tratamiento K100+AG50 presento mejores resultados respecto al peso del fruto (369,46 g), peso de frutos por planta (10,80 kg/planta), rendimiento por hectÃ...

Agromorphological characterization of cacao accessions in Peru is currently an important tool in the conservation and genetic improvement of cacao germplasm. The objective of this study was to carry out the morphological and agronomic characterization of 113 cacao accessions from the Huarangopampa germplasm bank. Tree, leaf, flower, fruit and seed descriptors were used. The data collected were processed by descriptive statistics using multivariate techniques. Five groups were formed according to similar characteristics. The accessions of group 1 are vigorous trees with an pod index of 19.27 pods/kg of seeds; the groups that presented better differential characteristics were group 2 with erect tree architecture, intermediate vigorousness, purple seed color and pod index of 20.07 pods/kg of seeds and group 3, which had the highest number of accessions with the lowest pod index of 18.77 pod...
