Abstract
This study was conducted to evaluate the efficacy of β-aminobutyric and Bion in protecting tomato plant from tomato mosaic virus infection when soaking tomato seeds in these compounds. This study was included experiments conducted in the glass house and in the plastic house at Department of plant protection, College of Agriculture- University of Baghdad. The glass house experiments included the biological and serological detection of the virus by using ELISA and preparation of pure isolate from the virus by using the single local lesion technique. While the plastic house experiments included the evaluation of performance of β-aminobutyric and Bion in reducing virus multiplication by biological and serological assay and the estimation of peroxidase activity and also percentage of virus infection was recorded. BABA 1% was showed the highest percentage of inhibition in number of local lesions formation on N. glutinosa which was reached 69.56%, and the size reduction of local lesion was 36.3% while there was no significant differences in 1% Bion treatment. Results of ELISA absorbance value were showed superiority of 1% BABA on 1% Bion and control which were 0.047, 0.113, 0.118 respectively, these results confirmed the results of the biological evaluation of the virus. BABA 1% was showed significant difference in the change of peroxidase absorption which was 99.85 while Bion 1% was not showed a significant difference. BABA 1% was caused a significant reduction percentage of ToMV infection which was 22.21% while Bion 1% was not significantly reduced virus infection percentage.
