Abstract | ||
This study was conducted to evaluate the efficiency of β-Amino Butyric Acid (BABA) in inducing systemic resistance in zucchini plants (Amjad variety) against Zucchini Yellow Mosaic Virus (ZYMV). BABA was used at 6000 PPM concentration to Spray the zucchini Plants. The efficiency of BABA was evaluated on the bases of inhibition percent of virus multiplication as estimated by ELISA value and peroxidase activity. Results revealed that ELISA value of spray β-Aminobuytric acid and directly planted then inoculated with ZYMV and re-sprayed again with the same acid was 0.785 at 405nm and the percent of virus multiplication inhibition was 63.18%.The total absorbance change of peroxidase increased by 56.53 and 46.93 after 7 and 21 day respectively. This treatment was significantly different from control treatment where the inoculation of virus and sprayed distilled water, ELISA value was 2.132 and peroxidase absorbance 42.06 and 45.73 after 7, 21 day respectively and the percent of virus multiplication inhibition was 0%. The β- Aminobuytric acid has highly efficient effect in reducing losses of number and weight of zucchini fruits of treated plants. | ||
