| dc.description.abstract | La fase experimental del presente trabajo se realizó en la localidad de Virú, región La Libertad, en el cultivo de palto (Persea americana Mill.) variedad Hass, afectado por la “arañita roja” Oligonychus beeri, plaga que provoca daños en las hojas y afecta en el proceso de fotosíntesis. El objetivo fue determinar la relación entre el nivel de daño en la planta ocasionado por este ácaro y el contenido de clorofila (µg/g p.f.) y rendimiento (t/ha). Se empleó un diseño completamente al azar (DCA) en árboles clasificados en cuatro tratamientos, según el grado de daño predominante en las hojas de cada planta: T0 (Testigo), T1 (Nivel Bajo), T2 (Nivel Medio) y T3 (Nivel Alto). Los resultados obtenidos mediante el programa estadístico R-Studio evidenciaron diferencias significativas entre tratamientos (p0.05). Los resultados sugieren que el daño foliar ocasionado por O. beeri no repercutió de manera significativa en el rendimiento del cultivo de palto durante la campaña evaluada. | |
| dc.description.abstract | The experimental phase of this study was conducted in Virú, La Libertad region, on Hass avocado orchards. This area is affected by a significant pest called the “red spider mite” Oligonychus beeri, a pest that causes damage to leaves and affects the photosynthesis process. The objective was to determine the relationship between the level of damage caused by this mite and chlorophyll content (µg/g f.w.) and yield (t/ha). A completely randomized design (CRD) was used with trees classified into four treatments according to the predominant level of leaf damage in each plant: T0 (Control), T1 (Low Level), T2 (Medium Level), and T3 (High Level). The results obtained using the R-Studio statistical software showed significant differences among treatments (p<0.05) for chlorophyll a, chlorophyll b, total chlorophyll, a/b ratio, and carotenoids. Treatment T0 showed the highest contents of photosynthetic pigments, whereas T3 recorded the lowest values. Likewise, during harvest, the variables number of fruits and total fruit weight (kg) per plant were evaluated. Statystical analyses using ANOVA and Tukey's test indicated the treatments with higher damage levels of damage caused by the O. beeri (T2 and T3) presented a greater number of fruits compared to T0 and T1. However, no significant differences were found among treatments for yield (t/ha) (p > 0.05). The results suggest that foliar damage caused by O. beeri did not significantly affect avocado yield during the evaluated season. | |
