Özet
Seed-borne fungal diseases are major biotic constraints to seeds. This study was conducted to determine identification and incidence of seed-borne fungal disease agents on seeds of different bottle gourd [Lageneria siceraria (Mol.) Standl.] genotypes which were collected from different parts of Turkey bottle gourd seeds. Using agar plate and blotter method as recommended by ISTA, the seed-borne mycoflora of 21 different samples of bottle gourd seeds collected from infested plants growing in the different parts of Turkey was investigated. Agar plate method yielded greater number of fungi followed by blotter method. The occurrence and average per cent incidence of fungi in seed samples tested revealed that Macrophomina phaseolina, Fusarium oxysporum, Epicoccum purpurascens and Sordaria fimicola were the most frequently isolated seed-borne fungal agents from 70.0, 10.0, 9.5 and 4.6% seed lot samples of bottle gourd, respectively. The sources of primary inoculum in seeds are still not well documented but indications suggest that keeping bottle gourd fruits in fields for maturations play an important role in disease transmission from soils. Seed treatment may prove useful as a part of an integrated disease management approach based on improved resistance and good agronomy.
