Abstract

In 2012, a pink mold rot was observed on apple (Malus pumila var. dulcissima Koidz.) at the Wholesale Market for Agricultural Products, Jinju, Korea. The first symptom of pink mold rot on apple fruit is a water-soaked appearance of the affected tissue and surface fruit formed pink mold rot, then became brown and produced a mass of powdery pink conidia spores. Colony was fast growing colonies, pinksh, zonate in diurnal rhythm, powdery from conidia. Optimum temperature for mycelial growth was $25^{\circ}C$. Conidia were hyaline, smooth, two-celled, thick-walled conidia with truncate bases, ellipsoidal to pyriform, and characteristically held together zig-zag chains and $12-26{\times}8-12{\mu}m$ in size. Conidiophore was erect, colorless, unbranched, and $4-5{\mu}m$ wide. On the basis of mycological characteristics, pathogenicity test, and molecular identification with the ITS region, the causal fungus was identified as Trichothecium roseum (Pers.) Link ex Gray.

2012년 경상남도 진주시 농산물도매시장에서 구입한 사과에서 분홍빛열매썩음병이 발생하였다. 병징은 사과 과실 표면이 갈색으로 변하면서 약간 함몰되어지고 수침상으로 물러지고 썩으면서 그 위에 분홍빛 곰팡이가 형성되었다. 감자한천배지 위에서 균총의 색깔은 처음 흰색이고 배양기간이 경과됨에 따라 분홍빛의 분생포자가 많이 형성되었다. 균사생육 적온은 $25^{\circ}C$이었다. 분생포자의 모양은 서양배형이며 좌우 지그자그로 부착하며 성숙한 분생포자는 2개의 세포로 되어있다. 크기는 $12-26{\times}8-12{\mu}m$이었다. 분생자경은 균사표면에 직립으로 형성하고, 폭이 $4-5{\mu}m$이고 무색이었다. 위와 같은 결과를 통해 사과에서 발생한 병징과 병원균의 균학적 특징을 기초로 하여 이 병을 Trichothecium roseum (Pers.) Link ex Gray에 의한 사과 분홍빛열매썩음병으로 명명하고자 제안한다.
