A Method for in Vitro Testing Strawberry Susceptibility to Verticillum Wilt
ثبت نشده
چکیده
A method was developed for evaluating strawberry susceptibility to Verticillium wilt in in vitro conditions. Micropropagated strawberry shoots of 15 strawberry cultigens, differing in susceptibility to the disease in field conditions, were treated in vitro with fungal homogenate of Verticillium dahliae, diluted with sterile water in a proportion of 1:10 in order to decrease the pathogen’s pressure. The susceptibility was estimated on a 6-point ranking scale based on infection symptoms occurring on the shoots. The results obtained in in vitro test were consistent with the susceptibility of strawberry genotypes to Verticillium wilt in the field.

EFFICACY OF RESISTANCE SELECTION TO VERTICILLIUM WILT IN STRAWBERRY (Fragaria x ananassa Duch.) TISSUE CULTURE
The soil-borne pathogenic fungus Verticillium dahliae Kleb. causes economic losses in crops in temperate regions of the world and hence is the most studied species. Strawberry (Fragaria x ananassa Duch.) belongs to plant species susceptible to Verticillium dahliae, although the response to infection caused by this pathogen is varied and depends on the cultivar. Due to a lack of efficient method...

Fusarium wilts of strawberry, caused by Fusarium oxysporum f. sp. fragariae, is a serious soil-borne disease. Fusarium wilt causes dramatic yield losses in commercial strawberry production and it is a very stubborn disease to control. Reliable chemical control of strawberry Fusarium wilt disease is not yet available. Moreover, other well-known F. oxysporum have different genetic information fro...

Background and Purpose: Candida species are the most opportunistic fungi affecting the nails and resulting in onychomycosis. In this study, we identified and evaluated in-vitro susceptibility of the recovered isolates against fluconazole (FLC), voriconazole (VRC), and clotrimazole (CLT) using the Clinical and Laboratory Standards Institute (CLSI) M27-A3 document. Materials and Method...
