“…The results suggest that C. pubescens seed development occurs at the same time of physiological fruit development and when occurs maturing (intense red color- Figure 1), seed quality starts to deteriorate (Bewley, Bradford, Hilhorst & Nonogaky, 2013;Espindola & Smiderle, 2014). However, the results are diferent for C. annuum, C. frutencens and C. baccatum (Ayala-Villegas et al, 2014;Bezerra et al, 2014;Spindola and Smiderle, 2014).…”

“…For total emergence (TE), the number of emerged seedlings was counted every third day (Pacheco & Zuñiga, 2007;Espindola & Smiderle, 2014). Mean emergence rate (MER), was defined as the number of seedlings that emerged in the interval i, divided by the number of days in the interval i.…”

“…This species is cultivated in Andean ecosystems and is characterized by violet flowers and black seeds (Ibiza, Blanca, Canizares & Nuez, 2012;Espindola & Smiderle, 2014). Fruits of C. pubescens can be considered as nutraceuticals for their content of phenolic compounds, which promote optimal brain cell function by inhibiting oxidation of essential fatty acids (Oboh & Rocha, 2007).…”

Quality of rocoto pepper (Capsicum pubescensRuiz AbstractRocoto pepper (C. pubescens), is one of the domesticated species of the genus Capsicum in South America. Currently, its supply and demand are arising in national and global market. The aim of this study was to determine the optimal extraction timing of the seeds of C. pubescens according to physiological and physical seed qualities. Seed qualities measurement include seed weight, number of seeds per fruit, total emergence, emergence rate, mean emergence time, mean daily emergence, survival percentage, peak value and emergence value. Treatments were evaluated for comparison as follows: seed extraction ranged from 0 to 3 days after harvest (T1), and seed extraction ranged from 14 to 17 days after harvest (T2). T1 presented seeds with the best physiological qualities and a total emergence value of 84.2%, in contrast to 74.8% obtained in T2. A positive correlation was found between seed size, number of seeds per fruit and overall quality, respectively. Based on the results of this study, is recommended to use and conserve the seeds extracted immediately after harvest, as well as larger seeds from biggest fruits.Key words: Agri-food; Andean region; seed characteristics; seed emergence; seed size; seed viability; seed vigour; sexual propagation. ResumenEl ají rocoto (C. pubescens) es una de las especies domesticadas del género Capsicum en Suramérica. Actualmente, su oferta y demanda están en aumento tanto en el mercado nacional como global. El objetivo del estudio fue determinar el momento óptimo de extracción de las semillas de C. pubescens en función de su calidad física y fisiológica. Las mediciones de calidad incluyeron el peso de semillas, número de semillas por fruto, emergencia total, taza de emergencia, tiempo medio de emergencia, emergencia media diaria, porcentaje de sobrevivencia, valor pico y valor de emergencia. Los tratamientos fueron evaluados por comparación como sigue: (T1), extracción de semillas de 0 a 3 días después de cosecha y (T2), extracción después de 14 a 17 días, respectivamente. T1 presentó semillas con mayor calidad fisiológica y un valor de emergencia total de 84.2 %, en contraste con 74.8 % obtenido en T2. Se encontró una correlación positiva entre el tamaño y el número de semillas y la calidad de las mismas. Con base en los resultados de este estudio, se sugiere usar y conservar las semillas extraídas inmediatamente después de la cosecha, así como semillas de mayor tamaño provenientes de frutos más grandes.Palabras clave: Agroalimentaria; características de semilla; emergencia de semilla; propagación sexual; región Andina; tamaño de semilla; viabilidad de semilla; vigor de semilla.

“…Also, it can increase the seed's production, because the ideal harvest span diminishes the quantity of immature seeds. Studies on maturation and seed harvest have been shown in a variety of crops (Freitas et al, 2007;Medeiros et al, 2010;Nakada et al, 2011;Duarte et al, 2012;Figueiredo Neto et al, 2012;Lima & Smiderle, 2014). However, in species where maturation is irregular, such as coriander, research are still scarce.…”

A B S T R A C TThe season of harvest is one of the most important factors influencing seed quality. This study evaluated the effect of different harvesting times on the physiological quality of Coriandrum sativum L. seeds, cv. Palmeira. The experimental design was completely randomized, with six treatments (harvest times) and four replications. The experiment was conducted during the months of April to October 2010. The first moment to harvest seeds was carried out 15 days after full bloom, when approximately 50% of plants were in flowering phase. Other harvests (22, 29, 36, 43 and, 50 days after bloom) were carried out at 7 days intervals until the seeds reached 16.0% of moisture, which occurred in the 6 th harvest. Immediately after each harvest, the seeds were analysed for water content, germination and vigor (first count, seedling emergence and emergence rate index). The harvest season most suitable for C. sativum seeds cv. Palmeira occurred between 46 and 50 days after flowering, when the seeds have the highest physiological quality and moisture content between 20 and 16%.Diferentes épocas de colheita e qualidade fisiológica de sementes de coentro R E S U M O A época de colheita é um dos fatores mais importantes que influencia a qualidade das sementes. Este estudo avaliou o efeito de diferentes épocas de colheita na qualidade fisiológica de sementes de Coriandrum sativum L., cv. Palmeira. O delineamento experimental foi inteiramente casualizado, com seis tratamentos (épocas de colheita) e quatro repetições. O experimento foi conduzido durante os meses de abril a outubro de 2010, em que a primeira época de colheita das sementes foi realizada aos 15 dias após a floração quando aproximadamente 50% das plantas apresentavam flores. As demais colheitas (22, 29, 36, 43 e 50 dias após floração) foram realizadas em intervalos de 7 dias até as sementes atingirem aproximadamente 16% de umidade, o que ocorreu na 6ª colheita. Imediatamente após cada colheita as sementes foram avaliadas quanto ao teor de água, germinação e vigor (primeira contagem, emergência de plântulas e índice de velocidade de emergência). A época mais adequada para a colheita de sementes de C. sativum cv. Palmeira ocorreu entre 46 e 50 dias após a floração quando as sementes apresentaram a mais alta qualidade fisiológica e teor de umidade entre 20 e 16%.

“…Conversely, Abud et al (2013) observed increases in the germination percentage of malagueta hot pepper seeds from 40 to 71 DAA and of biquinho hot pepper seeds between 40 and 79 DAA, which resulted in 86% and 89% germination, respectively. Similarly, Lima and Smiderle (2014) noted that malagueta hot pepper seeds extracted from "red" fruits (between 66 and 70 DAA) resulted in 84% germination. This variation in the number of days until the increase in germination that has been reported in the literature showed that growing environments had strong effects on intraspecific and species-related seed maturity in the Capsicum genus, which provided an explanation for the findings of these studies on hot peppers.…”

The cultivation of chili peppers (Capsicum spp.) plays a key role in the fresh vegetable, condiment, and preserve markets. The determination of the harvest season suitable for seed production is crucial to obtain high-quality seeds and ensure production success. Therefore, this study aimed to determine the harvest season of 'dedo-de-moça BRS Mari' hot peppers that provides the maximum seed physiological potential. The flowers in anthesis were labeled daily and the fruits were harvested 25, 40, 55, 70, 85, and 100 days after anthesis (DAA) and classified as green, yellowish green, orange, red, extreme red, and intense red, respectively. The seed physiological potential was determined by using the water content, dry matter, germination, first germination count, germination rate index, and accelerated aging tests. The seed dry matter increased steadily until 55 DAA (3.95 mg per seed), then increased slightly to 70 DAA (4.05 mg per seed), and stabilized from 85 to 100 DAA. The harvested seeds began to germinate at 55 DAA with approximately 40% germination, which peaked at 70 DAA with 87% germination; this value was maintained until 100 DAA. The highest values of the germination rate index were found at 70, 85, and 100 DAA. An increase in seed vigor was observed, based on the accelerated aging test, which peaked at 85 DAA and subsequently decreased. The peppers were harvested between 70 and 85 DAA and red to extreme red were found to be the most recommended colors to obtain 'dedo-de-moça BRS Mari' hot pepper seeds with high physiological potential.
