In this study, the effect of different substrates of agricultural by-products on the mycelial growth rate and density of Trametes versicolor (Turkeytail mushroom) was analyzed. We found that pepper stem and rice bran with a mixing ratio of 9:1(v/v) produced the best mycelial growth of 101 mm in 10 days, while a mixing ratio of 8:2 resulted in mycelial growth of 83 mm in 10 days. The control group treated with a 9:1 mixing ratio of oak sawdust and rice bran (v/v) produced mycelial growth of 74 mm in 10 days. The following results are in the order of beanstalk, sesame stem, and perilla stem. After the harvest of the mushrooms, the mycelial growth rate and the density of T. versicolor in each substrate were as follows the group with waste substrate of Pleurotus eryngii and rice bran with a mixing ratio of 9:1(v/v) produced the best result of 76 mm in days, while a mixing ratio of 8:2 produced of 61 mm in 10 days. The control group with a 9:1 ratio of oak sawdust and rice bran produced mycelia of 74 mm in 10 days, while a mixing ratio of 8:2 resulted in mycelia of 59 mm in10 days.

참깨줄기의 반쪽부분(部分)만이 특징적으로 변색(變色)되며 결국은 식물체전체(植物體全體)가 고사(枯死)되는 병미(病微)이 장려품종(奬勵品種)인 광산(廣産)깨와 풍년(豊年)깨가 심겨진 포장(圃場)에서 관찰(觀察)되었다. 병미(病微)은 처음에 줄기의 한쪽 부분(部分)만이 수침상(水浸狀)의 줄무늬(條斑)형태(形態)로 변색(變色)되며, 병징후기(病徵後期)에는 변색부위상(變色部位上)에 황백색(黃白色)선홍색(鮮紅色)의 Fusarium 포자퇴(胞子堆)들이 많이 형성(形成)된다. Fusarium oxysporum에 감염(感染)된 참깨 유묘(幼苗)에서는 주로 시들음 증상(症狀)이 나타나지만, 성묘(成苗)에서는 토양접종(土壞接種)이나 상처접종(傷處接種)에 의해 줄기반쪽썩음증상(症狀)을 재현(再現)시킬 수 있었다. 본(本) 병해(病害)는 주로 생육후기(生育後期)인 7월하순(月下旬) 경에 많이 발생(發生)된다. 참깨줄기반쪽썩음증상(症狀)에서 분리(分離)한 Fusarium oxysporum의 균학적(菌學的) 특성(特性)을 이미 참께시들음병(病)에서 보고(報告)되어 있는 Fusarium 균(菌)들과 비교(比較)한 결과(結果) 본(本) 균(菌)은 F. oxysporum f. sp. sesame로 생각된다.

“ Namahn” (Sesamum indicum L.) was developed at the National Honam Agricultural Experiment Station (NHAES) in 2001. It was derived from the cross between “Suwon87 ” of white seed coat color and short stem, and “Nongki S-2” of phytophthora blight tolerance

A new sesame variety 'Namback'was developed at the National Crop Experiment Station through a cross between commercialiy utilized varieties of high yielding 'Danbackkae' and late seeding of second cropping daptable 'Chinjukkae' at 1989 and had been select
