Heilongjiang Forest Botanical Garden, Harbin 150040, Heilongjiang, China Abstract: Using growth rate and hanging drop methods, biological activity of four acetone extracts from Sophora flavescens Ait., Galinsoga parviflora Cav., Typhonium giganteum Engl., and Datura stramonium L.

黑龙江省森林植物园，黑龙江哈尔滨 150040 摘要：采用生长速率法和悬滴法测定了苦参、牛膝菊、独角莲、蔓陀萝4种植物的丙酮提取物对水稻恶苗病菌、稻瘟病菌、玉米小斑病菌、玉米弯孢菌叶斑病菌、番茄叶霉病菌和辣椒根腐病菌的生物活性。

Methods: The marine bacteria were isolated with the infinite dilution and plate streak technique and screened for antimitosis active strains by Pyricularia Oryzae model. The active strain 32-11-2-2 was subjected to morphological, physiological and biochemical study, and was classified by the analysis of the 16S rDNA sequence. Results A total of 421 strains of marine bacteria were isolated from marine water and sediment samples; 54 of them had antimitotic activity.
