ABSTRACT

Fig viruses have been found as naturally mixing infection in many countries in the world and Egypt. The present study aimed to evaluate the potential effect of nanochitosan and biomagic for treatment of the pathological effects related to virus infection in fig plants. The fig (Ficus carica L.) cv. sultani) plants were grafted by infectious blind eye from Fig latent virus (FLV) infected plants. Infected and healthy plants were foliar sprayed with nanochitosan (ChNPs), biomagic (BM) or combination (ChNPs and BM). Microtome and ultrathin sections were carried out on healthy and infected treated fig leaves. The shoot length, leaf area, fresh and dry weight were determined. Biochemical markers as indicators for systemic acquired resistance; total proteins, salicylic acid, phenol, proline, oxidative enzyme activities (polyphenol oxidase and superoxide dismutase) and virological assessments were assayed. Reduction in the disease severity of treated foliar ChNPs and BM fig plants was recorded. Systemic acquired resistance was detected related to Chlorophyll a and b and carotenoid, Phenol, Proline, salicylic acid and oxidative enzymes contents. The microtome and ultrathin section analysis revealed that improved phytosanitary of cell and tissues of FLV infected fig plants treated with ChNPs and BM, as well as improved shoot length, leaf area and dry weight. Biochemical markers as indicators for systemic acquired resistance were significantly increased including total proteins, salicylic acid, phenol, proline, Peroxidase, polyphenol oxidase and superoxide dismutase activities Nanochitosan and biomagic were treated and improved tissues, cell membranes, chloroplasts, mitochondria, and nucleus damage caused by FLV infection in fig plants. Treatment of fig plants with nanochitosan and biomagic led to a significant increase in plant health, growth characteristics, immunity against virus infection, as well as repair of the effects caused by the FLV infection. It has been suggested that, the induction of systemic acquired resistance was successfully achieved and protected fig plants against FLV infection.
