| Abstract: | Aralia elata(Miq.) Seem,an arbor of high economic value,has been cultivated extensively in recent years in China.Some diseases has occurred on the tree in the field and become more serious with the increase of planting areas.The yield and economic value decreased due to the prevailing of the diseases,and the disease has emerged to be a restricting factor to A.elata cultivation.According to the investigation of the diseases occurring on cultivated A.elata in Liaoning within a whole season,4 fungi were identified and were determined to be the pathogen of the disease by Koch's Rule.The disease symptoms and occurrence conditions were described as well.The data presented in this paper would help prevent the disease epidemics of A.elata and provided a basis for further research. |
