딸기 검은 무늬病菌, Alernaria alternate (Fr.) Keissler의 몇가지 培養的 性質, 營養生理 및 葉劑防除 效果에 대하여 實驗한 結果를 要約하면 다음과 같다. 1. 供試菌의 菌叢빛깔은 菌株, 培地, 溫度, vitamin 및 炭素源에 따라 差가 있었다. 2. 公試菌의 K-3菌株는 一般的으로 溫度, 培地, 炭素源 및 vitamin에 관계없이 K-2와 J-1菌株에 비하여 菌絲生長 速度가 빠르고 分生胞子가 많이 形成되었다. 3. 公試菌의 菌絲生長은 菌株 모두 天然培地에서는 良好하여 PDA에서 가장 效果的이었고 다음은 V-8 Agar, CMA의 順이었고 合成培地에서는 K-3菌株는 生長하였으나 K-2, J-1菌株는 극히 不良하였다. 分生胞子 形成은 菌株 모두 V-8 Agar에서 가장 많이 形成되었으며 그 외 公試培地에서는 저조하였다. 4. 公試菌의 菌絲生長과 分生胞子形成 溫度범위는 10~35℃이며 最適溫度는 28℃ 부근이었다. 5. 公試菌의 J-1, K-2菌株는 菌絲生長에 thiamine 결핍 菌株이었으나 K-3菌株는 pyridoxine 첨가에 의하여 生長이 촉진되는 경향이었다. 分生胞子形成은 菌株 모두 pyridoxine 添加에 의하여 촉진 되었고 inositol, biotin도 效果的 이었으나 thiamine은 오히려 胞子形成을 억제하였다. 6. 菌絲生長은 thiamine 濃度間에 뚜렷한 차이가 없었고 分生胞子形成은 K-3菌株에서는 pyridoxine 120r/l, J-1, K-2菌株에서는 100r/l에서 最高形成量을 나타내었다. 7 公試菌의 J-1, K-2菌株는 供試한 7種의 炭素源 모두 thiamine 또는 thiamine과 pyridoxine이 存在하지 않는한 菌絲生長과 分生胞子形成에 效果가 없었다. thiamine 添加될 경우 菌株 모두 菌絲生長에 있어서는 多糖類인 dextrin과 starch에서 가장 效果的이었고 分生胞子形成에 있어서도 多糖類인 starch, dextrin, 複糖類인 maltose, sucrose가 가장 效果的이었다. 8. 公試葉劑中 菌株에 관계없이 zineb, zimaneb가 本 病의 防除에 가장 效果的이었고 다음은 crovral, polpan, daconil, captan順이었다. The experiments were carried out to investigate the cultural characteristics, nutritional physiology and chemical control of Alternaria alternata, the causal fungus of strawberry black leaf spot. The results obtained were summarized as follows. 1. The color of colony surface of the fungus varied with the isolates, culture media, temperatures, vitamins, and carbon sources. 2. Of the 3 isolates tested, in general, isolate K-3 grew better and produced more conidia than did the other two isolates. 3. Of the 5 media tested, P.D.A. gave the most radial growth, followed by V-8 Agar and C.M.A., Richard`s Agar and Czapek`s Agar were the least, whereas isolate K-3 grew well on 2 synthetic media. Most conidia formed on V-8 Agar. 4. Optimum temperature for the mycelial growth and conidial formation of the fungus was near 28℃. 5. Of the 3 isolates tested, isolate J-1 and K-2 were thiamine-deficient organism, but isolate K-3 didn`t require thiamine-hydrochloride. Pyridoxine hydrochloride was the most effective on conidial formation of all 3 isolates, followed by inositol and biotin. 6. No statistically significant differences were convinced among the concentration of thiamine-hydrochloride for the mycelial growth and the oprimum concentration of pyridoxine-hydrochloride for the conidial formation was about 120r/l in isolate K-3, and 100r/l in isolates K-2 and J-1. 7. Seven kinds of carbon sources tested were not utilized by isolate J-1 and K-2, so far as thiamine-hydrochloride was not added. When thiamine-Lydrochloride was added, dextrin and soluble starch were the most favorable for the mycelial growth. In the conidial formation, soluble starch, dextrin, maltose and sucrose were the most effective. 8. Under the condition of artificial infection, zineb and zimaneb were the most effective in controling the strawberry black leaf spot and followed by roval, polpan, daconil and captan.

朴永道,裵泰雄 東亞大學校 1989 東亞論叢 Vol.26 No.1

A series of experiments were conducted to investigate the distribution ratio of the biotypes of brown planthopper(BPH), Nilaparvata lugens Stal, migrated into the rice field of Korean peninsula from southern Chinese continent during the rice crop growing season, the feeding amount, and the emergence rate of BPH biotypes fed on 60 to 70-day-old rice cultivars with different resistance genes. The percent biotype distribution of the female BPH collected in southern coastal regions of Korean peninsula showed that in 1986, 1987, and 1988 the BPH biotype-1 was predominant species accounting for 61.2%, 59.7%, and 52.4%, respectively. Whereas biotype-2 was 21.9%, 29.7%, and 26.2%, and biotype-3 was 17.0%, 12.6%, and 21.4%, respectively. Since Indonesian rice cultavars, IR 36, Cisadane, and Krueng Aceh, to the BPH female adults collected in southern coastal regions of Korean peninsula were shown partially susceptible reaction, the primary source seems to be migrated from the tropics to Korea by way of southern China and the subtropics. The feeding amount of biotype-2 on Cheongcheongbyeo with resistant Bph 1 gene and biotype-3 on Milyang 63 with resistant bph 2 gene was as high as Milyang 23 with no resistant gene. But Gayabyeo with resistant Bph 1 and bph 2 gene was highly resistnat to biotype-1,2,and3. The emergence ratio of the three BPH biotypes on Milyang 23 was higher than on the other rice cultivars, and that of biotype-2 on Cheongcheongbyeeo and biotype-3 on Milyang 63 was as high as on Milyang 23.
