הוספת תג | סיכום: | This research is to develop the "morphological characterization of plant pathogenic fungi in the cultivation of strawberry (Fragaria vesca) in the field of Salache Barbapamba Salcedo Canton province of Cotopaxi 2015" with the latitude coordinates: 1 ° 3 '0 "S, longitude 78 ° 35 '0 "W and altitude: 2480 meters above sea level, the goal is to characterize the plant pathogenic fungus morphologically greatest impact on production of strawberry (Fragaria vesca), by identifying signs and symptoms in the field, to characterize macro and microstructures describe the life cycle and develop a tutorial. The research was based on direct observation, to identify the signs and symptoms of the fungus, macro-images are captured, for the morphological characterization Trinocular microscope CX31 with adaptation to infinity chamber 1 was used as microstructural images are captured: (mycelium, conidiophores, conidia) using 20x and 40x lenses. By visiting and bibliographies consulted the phytopathogenic fungus greatest impact on strawberry (Fragaria vesca), which is Botrytis (Botrytis cinerea), identifies the signs and symptoms include irregular brown spots, fruits covered by a gray mycelium. In the laboratory macrostructures as cottony-white aerial mycelium and finally brown it was observed. The microstructures are identified: 19.83 septate mycelium elongated .mu.m, 24 .mu.m conidiophores with conidia at their ends and conidia with 5.7 .mu.m spherical shape. The fungus was grown in a temperature of 23.5 ° C and its life cycle is completed after 6 days of making the crop. With all this information a teaching guide was developed. It is recommended that this research be used and serve as a basis for determining the factors that influence agricultural production (control of the pathogen in different stages, microclimate, humidity, nutrition) to ensure precision agriculture. |
