في هذه الدراسة تمت مقارنة شراسة ست عزلات من النيماتودا Shmidt
Heterodera schachtii تم الحصول عليها من حقول في محافظات (حمص، حماة،
إدلب، حلب، دير الزور و الرقة)، و ذلك على نباتات صنف الشوندر السكري Rizor
(وحيد الجنين) في تجربة أصص تحت ظروف البيت الزجاجي، حسبت الكثافة النهائية
للنيماتودا Pf, و تم حساب معدل التكاثر RF لكل عزلة نيماتودية.
In this study, the virulence of six isolates of nematode
Heterodera schachtii Shmidt which had isolated from fields in
Syrian Governorates (Homs, Hamah, Idlib, Aleppo, Der-Azzoor and
Arraqqa), was compared on sugar beet in a greenhouse pot
experiment. Final populations of the nematode were calculated, RF
(Reproduction factor) of the nematode were calculated for every
isolate.
