| Abstract:
This study was carried out to determine the presence of Tomato spotted wilt virus (TSWV) in greenhouse-grown tomatoes and some weeds during growing seasons of 2005 and 2006 in Denizli Province of Turkey. 71 leaf samples and 7 fruit samples showing TSWV-like symptoms were tested using ELISA. The leaf samples showing positive results to ELISA test were also inoculated to indicator test plants. According to the results of ELISA tests, 43 out of 71 leaf samples, with the rate of 60,6% and 7 out of 7 fruit samples were found to be infected by TSWV. On the inoculated senstive herbaceous host plants including Nicotiana tabaccum cvs. Samsun, N. rustica L., N. glutinosa L. and Datura stramonium L. were observed necrotic local lesion, chlorotic and necrotic spots and rings on inoculated leaves and systemic mosaic, necrotic pattern, leaf deformation and stunding. The effect of some weed species that may act as reservoir of TSWV were also investigated in the region. 10 weed species belonging to 9 families were tested and 7 weed species were found to be infected by TSWV. | |
