Pre-depulping and depulping treatments and the emergence of queen palm seeds (Syagrus romanzoffiana [Cham.] Glassman)
The propagation of the palm Syagrus romanzoffiano is done sexually with seeds, making the process of obtaining new plants slow and difficult, especially on large scales. In addition, seed germination is slow, uneven and susceptible to degradation and loss of vigor because of embryo deterioration, ev...

| description | The propagation of the palm Syagrus romanzoffiano is done sexually with seeds, making the process of obtaining new plants slow and difficult, especially on large scales. In addition, seed germination is slow, uneven and susceptible to degradation and loss of vigor because of embryo deterioration, even under laboratory conditions. As a result of the lack of information on efficient depulping methods for queen palm fruits, the present study aimed to establish a depulping methodology that is less aggressive to embryos, maintaining emergence quality. This experiment was carried out in Goiânia, Brazil, using fruits from eight stock plants submitted to three pre-depulping treatments (control, fermentation and drying) and two depulping methods (industrial depulping and concrete-mixer with the addition of gravel). After the different pre-sowing processes, the fresh and dry pyrenes mass, remaining fibers adhered to the pyrene and seedling emergence were evaluated. The pulper removed an average of 45% more pyrene pulp than the concrete mixer. However, these methodologies did not result in differences in the emergence of plants, which was affected only by the pre-depulping treatment, with superiority in the use of fresh fruits. Thus, the pulper was more efficient for the removal of pulp and pulp fibers than the concrete mixer. The depulping method did not significantly affect the pyrenes mass. Higher seedlings emergence values were observed for the fresh fruits that were pulped and sown immediately. Fermentation and partial pulp dehydration exert a negative influence on seedling emergence. |

La propagación de la palma Syagrus romanzoffiano se realiza sexualmente a través de semillas, lo que hace que el proceso de obtención de nuevas plantas sea lento y difícil, especialmente a gran escala. Además, la germinación de la semilla es lenta, desigual y susceptible a la degradación y pérdida de vigor debido al deterioro del embrión, incluso en condiciones de laboratorio. Debido a la falta de información sobre métodos eficientes de despulpado de frutos de palma reina, con el presente estudio se buscó establecer una metodología de despulpado menos agresiva para el embrión, manteniendo la calidad de la emergencia de las plántulas. El experimento se llevó a cabo en Goiânia, Brasil, utilizando frutas de ocho plantas de stock sometidas a tres tratamientos de pre-despulpado (control, fermentación y secado) y dos métodos de despulpado (despulpado industrial y mezcladora de cemento más grava). Después de los diferentes procesos previos a la siembra, se evaluaron la masa de pirenos frescos y secos, la pulpa restante adherida al pireno y la emergencia de plántulas. Se observó que el despulpado industrial eliminó un promedio de 45% más de fibra del pireno que la mezcladora de cemento. Sin embargo, estas metodologías no presentaron diferencias en la emergencia de plantas, que se vio afectada solo por el tratamiento pre-despulpado, con superioridad en el uso de frutas frescas. Por lo tanto, se concluye que el despulpado industrial es más eficiente para la eliminación de pulpa y fibras en comparación con el mezclador de cemento. El método de despulpado no afectó significativamente la masa de pirenos. Se observaron valores de emergencia de plántulas más altos para las frutas frescas despulpadas y sembradas inmediatamente. La fermentación y la deshidratación parcial de la pulpa ejercen una influencia negativa en la emergencia de las plántulas.
