Determination of the Bioherbicidal Potential of the Endophytic Bacterial Isolates Against Common Purslane (Portulaca oleracea L.) and Field Bindweed (Convolvulus arvensis L.)

Öz

The use of environmentally friendly biological control strategies to manage weeds that cause yield and quality losses in plant production is highly compatible with sustainable agricultural practices. Recent studies have demonstrated that certain endophytic or epiphytic bacteria can suppress weed germination and growth. This study aimed to isolate endophytic bacteria that could be evaluated as putative Biological Control Agents (BCAs) for weed control and to determine their bioherbicidal activity. In this context, nine dominant BCA bacterial isolates with district morphological characteristics were obtained from the seeds of common purslane (Portulaca oleracea L.) and field bindweed (Convolvulus arvensis, L.) which are important weed species exhibiting stunted growth or poor vigour in the field. Seven isolates were identified as Gram positive and two as Gram negative. Four isolates, that gave negative results in tobacco hypersensitivity reaction, potato soft rot, and growth tests at 37 °C, were identified as Pseudarthrobacter oxydans P1, Paenibacillus polymyxa P5, Curtobacterium flaccumfaciens pv. flaccumfaciens C1, and Bacillus megaterium C3 using MALDI TOF MS method. The C. flaccumfaciens pv. flaccumfaciens C1 isolate, originating from C. arvensis, induced typical disease symptoms in pathogenicity tests on bean plants. This study demonstrates for the first time that C. arvensis is an alternative host for C. flaccumfaciens pv. flaccumfaciens. In pot experiments, P. oxydans P1 and P. polymyxa P5 inhibited the germination of P. oleracea seeds by 76% and 85%, respectively, while C. flaccumfaciens pv. flaccumfaciens C1 and B. megaterium C3 reduced the germination of C. arvensis seeds by 51.7% and 58.6%, respectively, compared to the control. Furthermore, no adverse effects were observed on the germination of maize, cotton, or carrot seeds. These findings indicate that the selected bacterial isolates may be potential bioherbicide candidates in biological weed control by inhibiting the germination of weed seeds.
