Abstract
Selenicereus guatemalensis Eich “pitahaya” var. american beauty es una cactácea a cuyo fruto se le atribuye diversas bondades, por ello su cultivo se ha extendido en diversos países, convirtiéndose en uno de los frutos exóticos con más demanda económica. Para que el cultivo tenga buena producción y rentabilidad es importante los estudios de propagación sexual debido a que, permitirá mantener la variabilidad genética para el fitomejoramiento, por ello se propuso como objetivo de investigación determinar las características germinativas de Selenicereus guatemalensis “pitahaya” var. american beauty en condiciones de laboratorio. Los frutos fueron obtenidos en el mercado la Hermelinda, la fase experimental se realizó en el laboratorio de Biotecnología del Instituto de la Papa y Cultivos Andinos. Se implementó un diseño completamente al azar con 3 repeticiones y 100 unidades muestrales por placa y germinador. Con los datos obtenidos se evaluó el porcentaje de germinación, el porcentaje de emergencia, velocidad de germinación y vitalidad. Se concluye que las características germinativas son las siguientes; Germinación (85.7 %), velocidad de germinativa (6.87) semillas/ día, vitalidad de 15.08 % y porcentaje de emergencia (7.7 %).
Selenicereus guatemalensis Eich "pitahaya" var. american beauty is a cactus whose fruit has been attributed with various benefits, which is why its cultivation has spread to several countries, becoming one of the exotic fruits with the highest economic demand. In order for the crop to have a good production and profitability, it is important to carry out sexual propagation studies, since this will allow maintaining the genetic variability for plant breeding. For this reason, the research objective was to evaluate the germination characteristics of Selenicereus guatemalensis "pitahaya" var. american beauty under laboratory conditions. The fruits were obtained from the Hermelinda market, and the experimental phase was carried out in the Biotechnology laboratory of the Instituto de la Papa y Cultivos Andinos. A completely randomised design was implemented with 3 replications and 100 sample units per plate and germinator. The data obtained were used to evaluate germination percentage, emergence percentage, germination speed and vitality. It is concluded that the germination characteristics are the following; germination (85.7 %), germination speed (6.87) seeds/day, vitality of 15.08 % and emergence percentage (7.7 %).
