The influence of phytopathogenic fungi on the quality parameters of green bean seeds in period 2018-2022

Abstract

Green beans are among the most essential legumes because of their nutritional value. However, the production of green beans in Serbia suffers major decline due to significantly reduced yields, as well as the sown areas. Diseases caused by phytopathogenic fungi not only reduce yield and have the negative impact on total germination and seed quality of green beans, but also some phytopathogenic fungi can produce mycotoxins, adversely affecting human health. In this paper, the quality parameters of two green bean varieties (GB1 and GB2) were monitored for quality traits over a period of five years on the territory of Smederevska Palanka. The energy germination and total germination were the highest in the first observed year and amounted to 63% and 88% for GB1, respectively. For GB2 the energy germination and total germination (2018) were 71% and 75%, respectively. A significant decline in total germination was determined in 2020. and amounted to 75% for GB1 and 67% for GB2( p0.05). The impact of phytopathogenic fungi on green beans was reflected in the reduction of total germination, and therefore in seed quality and yield. The priority of future research is the application of biotreatments that will contribute to seed protection and improve total germination, and thus the yield in the field.
