Host Penetration And Infection By The Anastomosis Groups Ofrhizoctonia Solanikühn Isolated From Potatoes, Erkol Demi̇rci̇, M. Timur Döken
Turkish Journal of Agriculture and Forestry
The modes of penetration and infection of the isolates belonging various anastomosis groups (AG-2 type 1, AG-2 type 2, AG-3, AG-4 and Ag-5) of Rhizoctonia solani Kühn isolated from potatoes were investigated on the underground stems of the host. During the process of penetration, infection cushions were observed in all isolates in addition to the formation of labote appressoria by AG-3, AG-5 and direct hypel penetration of AG-4. Numerous fine infection pegs formed from infection cushions grew between or into epidermal cells following the penetration of cuticula. A similar mode of penetration was also occured by the infection peg produced …

Turkish Journal of Agriculture and Forestry
This study is concerned with the production of haploids of linseed. Anthers of eight genotypes were cultured both on solid and in liquid medium. It was found that callus induction rate was low in both media and also the cultivars significantly affected callus induction rate both on solid and in liquid medium. The cultivar Blue-Chip gave, on average, the maximum (3.67%) callus induction rate on solid medium and the cultivar Antares gave, on average, the maximum (3.35%) callus induction rate in liquid medium. The cultivar Norman produced callus on solid medium but did not produce any callus in liquid medium. …
