EVALUATION OF ENDOPHYTIC BACTERIAL ISOLATES ON GERMINATION AND HAUSTORIUM INITIATION OF STRIGA HERMONTHICA (DEL.) BENTH.
Journal Title: International Journal of Farming and Allied Sciences - Year 2015, Vol 4, Issue 3
Abstract
Fourteen endophytic bacteria isolated from sugarcane were evaluated in the laboratory for their ability to induce Striga hermonthica germination and/or haustorium initiation in response to different stimulants. The results indicated that bacterial isolates IS30 and IS18 significantly induced germination of Striga relative to the control. They enhanced germination by 14 and 19%, respectively in response to the lower concentration of growth regulator (GR24) (0.01 ppm). Isolate IS20, applied after conditioning, induced germination albeit not significant and inhibited germination significantly during conditioning. Haustorial initiation in response to 2, 6- dimethoxybenzoquinone (DMBQ) showed differential response to bacterial isolates. Isolate IS30 significantly induced haustoria in response to DMBQ at the lower concentration as compared to the medium control, it induced haustoria by 31%. However, the combination of IS20 plus IS29 caused significant reduction in haustoria, it reduced haustorium initiation by 29 to 53%. According to the morphological and biochemical characteristics, bacterial isolates ISO20, ISO29 and ISO30 were suspected to belong to Gluconacetobacter spp. The results suggested that endophytic bacteria are promising candidates for further studies to combat S. hemonthica in the low-input farming.
