“…Thus, the selection of chemical seed scarification treatments must consider the species, concentration, and immersion time. In that regard, Merino-Valdés et al (2018) observed the destruction of Capsicum pubescens Ruiz & Pav. seeds immersed for 30 min in 100, 75, and 65% H 2 SO 4 solutions.…”

Physiological potential of piquin pepper seeds in response to pregermination treatments

Wild piquin pepper fruits are consumed and traded because of their flavor, nutritional and pharmaceutical properties. The heterogeneous germination of its seeds has caused pregermination treatments to be unstandardized. Because of that, our goal was to evaluate pregermination treatments of piquin pepper seeds from a wild plant from the municipality of Victoria, Tamaulipas, Mexico, consisting of immersion for different periods (2, 24, 48 h) in solutions with variable concentrations of the growth regulators naphthalene acetic acid (NAA; 0.1, 1.0, 2.5 mM), salicylic acid (SA; 1.0, 5.0, 10 mM), gibberellic acid (GA3, 1.0, 5.0, 10 mM), indole-3-butyric acid (IBA; 1.0, 2.0, 3.0 mM), the commercial product Biozyme (Bioz) containing minerals and growth regulators (Bioz; 0.5, 1, 2%), and sulfuric acid (H2SO4; 2, 5, 10%) in a completely randomized design, using distilled water as the control. For each treatment, we measured the imbibition ratio, germination percentage, time to obtain 50% germination (T50), and coefficient of variation of germination time (CVt). Our results showed that the imbibition was similar in the control and the treatments, but it differed between treatments. The highest imbibition recorded in 48 h was 87%. The highest germination percentage (79.2%) was achieved with 2 h immersion in 2% Bioz, followed by 1 mM NAA (62%) and 5 mM SA (56%). T50 and CVt were 10-26 d and 0-39%, respectively. According to our results, we concluded that the pregermination treatments we assayed improved the physiological potential for the germination of piquin pepper seeds.

“…Poder contar con patrones de identificación, caracterización y evaluación de plantas cultivadas, es importante para conocer la variabilidad de caracteres dentro y entre plantas, y además, permite la selección de los caracteres cualitativos o cuantitativos más útiles para la correcta descripción [12]. La caracterización morfológica, debe registrar caracteres altamente heredables, fácilmente evaluados a simple vista y que se expresan sin la influencia de los ambientes [13,14]. De acuerdo con Raven et al [15], los órganos más importantes para la descripción morfológica son la flor y el fruto, así como las hojas, tallos, raíces y los tejidos celulares.…”

“…La caracterización se llevó a cabo con base en los descriptores para especies del género Capsicum [13], que consta de 62 descriptores, entre variables cuantitativas y cualitativas. Aunque se realizó la lectura de todos los descriptores, se optó por utilizar en los análisis, aquellos que tendían a ser más discriminantes.…”

Se utilizaron técnicas de mejoramiento genético convencional (premejoramiento) para selección de genotipos élite de mayor productividad y con mayor contenido de capsaicina y otros nutrientes, para recomendar a los productores sobre materiales de siembra de Capsicum chinense. En la caracterización morfológica y proximal de 45 introducciones, colectadas en Colombia, Brasil y México, se utilizaron 50 descriptores (seis para plántula, siete para hojas, ocho para flores, 17 para frutos, cuatro para semillas, ocho para rendimiento y características de calidad) entre los 62 propuestos para Capsicum. Para el ensayo en campo, se empleó un diseño en bloques completos al azar con tres repeticiones, con 10 plantas por parcelas, tomando cada introducción como un tratamiento diferente. Los datos cuantitativos fueron sometidos al test de normalidad (test Shaphiro-Wilk), análisis de variación y comparación de medias (test Tukey), utilizando el paquete estadístico Statistical Analysis System (SAS) 9.01, al nivel de 5% de significancia. Para analizar la correlación simple entre las variables se ha utilizado la correlación de Pearson. También se realizó un análisis de componentes principales (ACP), con la conformación de clústeres. Para datos cualitativos, se hizo un ACMF (análisis de correspondencia múltiple factorial). Los análisis mostraron una variabilidad genética entre las introducciones de Capsicum chinense; la determinan los caracteres relacionados con la morfología de la planta, como caracteres específicos de la flor, fruto y hojas. Dicha variabilidad puede ser de utilidad para iniciar un programa de mejoramiento genético. Además, el estudio contribuye para caracterización y premejoramiento de C. chinense, como una estrategia de uso y conservación de este recurso amazónico.

Objective: The objective of this research study was to obtain the varietal description of two varieties of manzano chili pepper in Las Montañas region, in central Veracruz, Mexico. Design/methodology/approach: The varietal characterization module was established under greenhouse conditions. The markers recorded were in accordance with the International Plant Genetic Resources Institute for Capsicum and the Graphic Handbook for Variety Description of manzano chili pepper. The plants were characterized from seedling in greenhouse to adult plant. The agronomic management of the crop was carried out in accordance with the manual for the production of manzano chili pepper in Las Montañas, state of Veracruz. Results: All qualitative markers were constant for the two varieties, MEXUVNE1-15-C2 and MEXUVCU1-16-C2, from seedling to fruit setting. In contrast, there were dissimilarities in plant height, and stem, leaf, flower, fruit and seed dimensions. Study limitations/implications: The pandemic caused by COVID-19 was the main limitation, resulting in some markers not being recorded in a timely manner as indicated in the Graphic Handbook. Findings/conclusions: Both varieties are very similar; however, the greatest distinction was in the quantitative markers, such as: plant height, fruit length, fruit diameter and number of seeds.
