Caracterización morfológica in situ de chile silvestre Pico de paloma (Capsicum frutescens) en Tabasco, México
2017
espanolActualmente el chile es uno de los cultivos horticolas mas importantes del mundo. El objetivo del presente trabajo fue realizar la colecta y caracterizacion in situ de la diversidad morfologica de chile silvestre Pico de paloma (Capsicum frutescens L.) del estado de Tabasco, Mexico. Se realizaron 66 colectas en campo en el 2014; tomando datos in situ de 25 variables de planta, de flor y de fruto. Con las 12 variables de mayor valor descriptivo se realizo un analisis de Componentes Principales (CP) y de conglomerados. Los primeros tres CP explicaron el 52.47 % de la variacion total entre colectas; el mayor aporte sobre la variacion la tuvieron las variables largo y ancho de hoja, altura de la planta, ancho de la planta, diametro del tallo, largo del fruto y peso del fruto. Mediante el analisis de conglomerados se formaron cuatro grupos en el dendrograma de variables seleccionadas. EnglishChili pepper is currently one of the most important vegetable crops worldwide. The objective of this work was to carry out the in situ collection and characterization of the morphological diversity of the dove’s beak wild chili pepper (Capsicum frutescens L.) in the state of Tabasco, Mexico. We collected 66 samples in the field in 2014, and we recorded in situ data of 25 of plant, flower, and fruit variables. A principal component (PC) and cluster analysis were conducted on the 12 variables with the highest descriptive values. The first three PC explained 52.47 % of the total variation between collections; the variables that contributed most to the variation were: were leaf length and width, plant height, plant width, stem diameter, fruit length, and fruit weight. Through cluster analysis, four groups were formed in the dendrogram of the selected variables.
