The biological characteristics of the pathogen of the tomato stem rot was studied. The results showed that the mycelia could grow better on PDA, PSA, 2%water agar, Richard,tomato juice,oatmeal and tomato oatmeal culture media, but worse on the 2%water agar culture medium. The temperature for mycelial growth ranged from 2 ℃ to 32 ℃, and 20 ℃ was the optimum. The mycelia could grow from pH3 to pH10, but pH5-7 was better.

对番茄茎基腐病病原菌生物学特性研究结果表明：病菌菌丝在供试PDA、PSA、2%水琼脂、Richard、番茄煎汁、燕麦片和番茄燕麦等7种培养基中均能良好生长，而在2%水琼脂培养基上生长较为缓慢；菌丝在2~32 ℃范围内均能生长，最适20 ℃，致死温度为50 ℃，10 min；菌丝生长的pH范围为3~10，最适为5~7；光照对菌丝生长影响较小。

Through investigation and study of the leaf blight disease of Lycium in 5 different areas in Mongolia, the pathogen was identified in-house as Alternaria tenuis Nees, biological characteristics of the pathogens, the bioassay of toxins from A. tenuis Nees, the pathogenic mechanism of toxin and the toxicity determination of the fungicide were studied.

通过对内蒙古5个不同地区枸杞叶枯病的调查研究，确定其致病菌为细链格孢菌，并对该菌的生物学特性、病原菌毒素活性检测、毒素的致病机理及几种药剂的室内毒力进行了研究。

The analysis methods for the determination of micro or trace elements in high moisture jellyfish were developed. The fatty acid compositions in difderent parts of fresh jellyfish were determined by GC/MS method. Thirty-five fatty acids were identified, and most of them were found in R. esculentum jellyfish for the first time. Especially, two unusual very long chain polyunsaturated fatty acids that were never detected in the other jellyfish also were determined. Amino acids were abundant in R. esculentum jellyfish, especially containing sulfur amino acids, and could be supplied for human diet. The polysaccharide in umbrella part of jellyfish was composed of glucose, galactose and uronic acid, and its molecular weight was 40,000, but the polysaccharide of the oral arms part consisted of glucose, mannose and glycuronic acid, and its molecular weight was 43,000. Above-mentioned data were never reported. The ethanolic extract of oral arms part of jellyfish were extracted by different polar solvents (petroleum ether, acetic ether, n-butanol), and antibacterial activity was tested to these extracts by four species of terricolous pathogenic bacilli and three species of botanic pathogenic fungi. The result demonstrated that the petroleum ether extract had certain bactericidal activity for two species of pathogenic bacilli, and n-butanol extract had certain inhibited activity on apple rot pathogenic fungus.

建立了 高含水量的海蜇产品中微量、痕量元素成分测定的分析方法；采用 GC/MS 方法测定了新鲜海蜇不同部位的脂肪酸组成，共鉴定出 35 种脂肪酸，其中大多数脂肪酸是首次在海蜇中被检测到，尤其是两种不常见的 C24：5 超长链多不饱和脂肪酸的分析和鉴定在其它水母种属中也从未见报道；海蜇三个部位中氨基酸成分齐全，含量丰富，含硫氨基酸含量较高，可与其它食物蛋白质的氨基酸互补；其中海蜇皮多糖是由葡萄糖、半乳糖和糖醛酸组成，分子量为 40，000，海蜇头多糖是由葡萄糖、甘露糖和糖醛酸组成，分子量为 43，000，以上工作均未见报道；利用石油醚、乙酸乙酯、正丁醇三种不同极性溶剂分别萃取海蜇头乙醇浸提物，用纸碟法和生长速率法分别对四株陆源病原菌和三株植物病原真菌进行了抑菌实验，结果表明海蜇头石油醚提取物和正丁醇提取物具有一定的抑菌活性。
