تأثير فيروس موزاييك التبغ (TMV)‎ في بعض أصناف البندورة-الطماطم في سورية

Abstract EN

Mechanical inoculation of the tomato varieties Bayonne-Fl, BB236, Carmello-Fl, Casterock-II, Evaline, F239 and Bandola-Fl with a local isolate of tobacco mosaic virus (TMV) caused considerable stunting of inoculated plants (56% in cv.

Evaline and 78% in cv.

Carmello–Fl).

Reduction of the root system of inoculated varieties was also noted.

Virus-inoculated plants did not produce typical symptoms of viral infection.

The leaf color was pale-green to purple, and virus was detected by back-inoculation.

Inoculated plants restored their growth, and gained gradually their natural green color, when they were sprayed with “Waxal” foliar fertilizer, and such plants did not show typical symptoms of viral infection but the virus was present as it was detected by back inoculation to indicator plants.
