| Title : | INFECTION RATE OF POMEGRANATE CULTIVARS BY ZITHIOUS FRUIT ROT IN THE CONDITIONS OF THE WESTERN PART OF AZERBAIJAN |
| Abstract : | Currently, the study of pomegranate diseases is one of the priority areas of phytopathological research in Azerbaijan. So, as this is the most important factor in the sustainable development of pomegranate production in Azerbaijan. The article presents the results of a 2-year (2019-2020) study on the susceptibility of local cultivars of pomegranate to zithia fruit rot (Zythia versoniana Sacc.) in the conditions of the western part of Azerbaijan. For this purpose, to study the cultivar susceptibility of the pomegranate, surveys were carried out in the Goranboy region on 2 cultivars (ꞌGulosha pinkꞌ and ꞌKrmyzy kabuhꞌ). Zythia fruit rot (Zythia versoniana Sacc.) in its negative economic value is one of the most harmful pomegranate diseases. As a rule, the disease begins in June and continues throughout the growing season of the plant, until harvest (late October - early November). Pomegranate fruits affected by zitiosis rot intensively during storage. Thus, zythia fruit rot (Zythia versoniana Sacc.) on pomegranate is characterized by great harmfulness both in the field and during storage of fruits. Since, the rotting of pomegranate fruits is 50-100%. In the fight against diseases, one of the leading places is the introduction of resistant cultivars into production. The identification of cultivars relatively resistant to zitiose fruit rot is of great national economic importance. As already noted, to determine the degree of infection of pomegranate cultivars with zitiosis, observations were made on two cultivars. As a result of experimental field studies, it was found that both examined pomegranate cultivars were to some extent susceptible to zithia fruit rot (Zythia versoniana Sacc.). The spread of the disease in 2020 on the ꞌKrmyzy kabukhꞌ cultivar did not exceed 26.3%, and the development was 14.2%; respectively, on the cultivar ꞌPink Guloshaꞌ, the spread is 17.4%, the development is 12.3%. Thus, both cultivars are characterized by comparative resistance. |
