Abstract

This research was conducted in 2019 year at Bayburt University, Aydintepe Vocational School experimental area (40°24’05.7”N 40°08’31.3”E) that it is in Turkey/Middle East and in the study Aydintepe local bean genotype was used. As a botanical and yield component features stem diameter, branch number, first pod height, pod length, pod width, pod number per plant, seed number per pod, 1000 seed weight, seed yield and as a stress features Proline concentration and Malondialdehyde (MDA) concentration parameters were examined in 0 (control), 1, 2, 3, 4, 5 and 6 Acanthoscelides obtectus Say. pest infected bean seeds. In addition to basic statistics, correlation coefficients between properties were calculated and variance analysis was also performed. According to the results obtained from the study, Acanthoscelides obtectus Say. beetle negatively affected the botanical and yield characteristics of the bean plants and it caused an increase in the concentration of stress substances such as Proline and MDA in the bean plants.
