Physiological quality of seeds from traditional and new recommended groups of Arabic coffee cultivars to highland regions

Abstract

The quality of a seed lot is an essential factor in the planning and implementation of any agricultural production program. Quality seeds provide strong and uniform plant growth. This study aims to analyze the physiological quality of seeds from different groups of Arabica coffee cultivars recommended for planting in the Brazilian highland regions. The seeds were picked from an Arabica coffee seed production field, accredited by the Brazilian Ministry of Agriculture, Livestock, and Supply, located in the municipality of Marechal Floriano, state of Espírito Santo (ES), Brazil. The experimental design was completely randomized, with four replications of 50 seeds each. The treatments were composed by traditional cultivars and new Arabica coffee recommendations from Catuaí Japi), and Sarchimor (Acauã, Arara) groups. The seeds were manually harvested in sieves, at the point of physiological maturation, processed, and dried until reaching a humidity of 35% ± 1%. Immediately following this, the seeds were taken to the Seed Analysis Laboratory,

Atributos físicos y fisiológicos de las semillas de café (Coffea arabica L)

“…Por otra parte, la calidad fisiológica es la capacidad que tiene la semilla para germinar, emerger y desarrollar plantas vigorosas y uniformes, cualidades esenciales para la toma de decisiones porque proporcionan información necesaria a productores de semillas y plántulas de café sobre la particularidad de la germinación y el vigor de cada cultivar (Reis et al, 2010). Asimismo, la calidad fisiológica puede estar directamente relacionada con los materiales genéticos estudiados (Alixandre et al, 2021). Además, esta característica puede ser usada para medir la tolerancia de la planta a ciertos estreses abióticos, como la falta de agua (Nijabat et al, 2023) y salinidad (Rosas et al, 2019).…”
