چکیده

Introducción: El cultivo de fresa se ve seriamente afectado por diferentes enfermedades que resulta en disminución la producción y calidad fruta. Dentro las más importantes atacan al encuentra Mycosphaerella fragariae, agente causal peca hoja estados avanzados puede llevar a perdida total los cultivos. monitoreo esta enfermedad es una herramienta fundamental para su prevención control. Las herramientas agricultura precisión 4.0 como imágenes obtenidas drones facilitar toma decisiones parte productores optimizan labores el monitoreo.
 Objetivo: En este estudio identificó relación entre porcentaje área afectada (Mycosphaerella fragaraiae) índices NDVI NDRE.
 Metodología: desarrolló provincia Pamplona Norte Santander con alta presión inoculo fragariae. Se colectaron foliolos plantas grados afectación causada material vegetal transportó garantizando conservación hasta laboratorio, donde realizaron mediciones espectrorradiómetro portátil EPP2000 marca Stellar Net, cuales tomaron valores banda roja, infrarroja del borde rojo cada realizar cálculo varios incluyendo NDRE, estos promediaron grado afectación. A hojas le calculó exacta partir software Compu eye leaf and symptom calcularon coeficientes correlación buscando lineal mutua regresiones lineales simples.
 Resultados: logró identificar índice NDRE correlaciona un 82% fragariae 70 %.
 Conclusión: fragariae) directamente relacionada respuesta espectral términos

Chlorophyll fluorescence in two strawberry (Fragaria x ananassa Duch.) cultivars Fluorescencja chlorofilu u dwóch odmian truskawki (Fragaria x ananassa Duch.)

The study of chlorophyll fluorescence (CF) parameters i.e.: Fo, Fm, Fv/Fm, Y, qP, qN, F’o, F’m was conducted in two strawberry cultivars ‘Honeoye’ and ‘Teresa’. Measurements of their values were done twice: in an early autumn and late spring. Fluorescence of five dark-adapted mature leaves derived from each cultivar was measured in the laboratory at room temperature with the use of a portable p...

EFFICACY OF RESISTANCE SELECTION TO VERTICILLIUM WILT IN STRAWBERRY (Fragaria x ananassa Duch.) TISSUE CULTURE

The soil-borne pathogenic fungus Verticillium dahliae Kleb. causes economic losses in crops in temperate regions of the world and hence is the most studied species. Strawberry (Fragaria x ananassa Duch.) belongs to plant species susceptible to Verticillium dahliae, although the response to infection caused by this pathogen is varied and depends on the cultivar. Due to a lack of efficient method...
