Abstract
El presente trabajo de investigación se realizó en el cultivo de Ananas comosus L. var. Roja Trujillana en la localidad de la Capilla de Poroto, geográficamente ubicado en las coordenadas: 17L 745505 9114591 UTM, y se desarrolló de mayo a diciembre del 2022, tuvo como objetivo principal describir las principales etapas fenológicas de Ananas comosus L. var. Roja Trujillana bajo condiciones de campo según la escala extendida del BBCH, determinando la duración de las fases fenológicas según los días de cultivo (DDC). El seguimiento de las fases fenológicas se realizó en una muestra de 22 plantas en distintas etapas fenológicas iniciales, en las cuales también se evaluó la altura de planta, número de hojas por planta; la longitud y diámetro de la inflorescencia e infrutescencia. Las fases evaluadas fueron siete y contaron con los siguientes periodos: Elongación del pseudotallo (1 año, 5 meses y 20 días), desarrollo de la hoja en desarrollo de la inflorescencia (27 días), emergencia de la inflorescencia (22 días), florecimiento (23 días), desarrollo de la infrutescencia (25 días), maduración de la infrutescencia (24 días) y finalmente la senescencia. Concluyendo que, para la zona de La Capilla en Poroto, Trujillo, la duración del ciclo fenológico del Ananas comosus L. var. Roja Trujillana es de 1 año, 9 meses y 19 días, que equivale a 658 días de cultivo (DDC).
ABSTRACT The present research work was carried out in the cultivation of Ananas comosus L. var. Roja Trujillana in the town of the bean of Poroto, geographically located at the coordinates: 17L 745505 9114591 UTM, and it took place from May to December 2022, its main objective was to describe the main phenological stages of Ananas comosus L. var. Roja Trujillana under field conditions, according to the extended scale of the BBCH, determining the duration of the phenological phases according to the days of cultivation (DDC). The monitoring of the phenological phases was carried out in a sample of 22 plants in different initial phenological stages, in which the plant height, number of leaves per plant were also evaluated; and the height and diameter of the inflorescence and infructescence. The evaluated phases were seven and had the following periods: elongation of the pseudostem (1 year, 5 months and 20 days), development of the leaf in development of the inflorescence (27 days), emergence of the inflorescence (22 days), flowering (23 days), development of the infructescence (25 days), ripening of the infructescence (24 days) and finally the senescence. Concluding that, for the area of The Chapel in Poroto, Trujillo, the duration of the phenological cycle of Ananas comosus L. var. Roja Trujillana is 1 year, 9 months and 19 days, which is equivalent to 658 days of cultivation (DDC).
