| description | The maturation status of seeds is fundamental at the harvest time to get high rates
of germination and vigor. The aim of this study was to determine the effect of harvest
time on the quality of pepper seeds. The trial was conducted in two bell type cultivars:
Fyuco INTA and Lungo INTA. Fruits were harvested at 4, 5, 6, 7, 8 and 9 weeks after
anthesis. Starting from the eighth week the average seed weight stabilized, coincidently
with the change in the fruit colour to red. Germination percentage increased linearly
as it increased the age of the seed. The electrical conductivity of the leachate was also
stabilized in seeds got from fruit harvested from 8 weeks after anthesis, showing that
they had reached physiological maturity. The results demonstrate to harvest the fruits of
pepper cv Fyuco INTA and Lungo INTA with over 8 weeks of age after anthesis to reach
high quality seeds. |

El nivel de maduración de la semilla es fundamental al momento de cosecha para obtener elevadas tasas de germinación y buen vigor. El objetivo de este trabajo fue determinar el efecto del momento de cosecha sobre la calidad de semillas de pimiento. El ensayo se realizó en dos cultivares tipo cuatro cascos: Fyuco INTA y Lungo INTA. Se cosecharon frutos a las 4, 5, 6, 7, 8 y 9 semanas después de la antesis. A partir de la octava semana el peso promedio de las semillas se estabilizó, coincidiendo con el cambio de coloración del fruto a rojo. La germinación se incrementó linealmente conforme aumentó la edad de la semilla. La conductividad eléctrica del sobrenadante se estabilizó también, en las semillas obtenidas de los frutos cosechados a partir de las 8 semanas después de la antesis, indicando que estas habían alcanzado la madurez fisiológica. Los resultados demuestran la importancia de cosechar los frutos de pimiento de estas cultivares con más de 8 semanas de edad para lograr semillas de calidad. Fil: Ruiz, Mónica B..
