南瓜病毒病的典型症状为皱缩有疱斑、甚至扭曲，病叶畸形，植株矮化；花叶叶片上出现淡绿色和深绿色相间的斑驳，有的斑驳明显黄化；蕨叶丛枝型：病叶不但严重花叶、畸形，而且叶肉组织极度退化，纤细呈蕨叫叶状，病株黄绿色，节间明显缩短，整个植株严重矮化丛枝状。

Arbuscular mycorrhizal symbiosis is the mutualistic association between AM fungi and most terrestrial plants: the plant roots offer carbohydrates to the fungi; in return, the fungi assist the plants with uptake of mineral nutrients, particularly phosphate, from soil, and their subsequent transfer to the root cortical cells.

南京农业大学资源与环境科学学院，南京 210095摘要丛枝菌根(arbuscular mycorrhizal， AM)共生是丛枝菌根真菌与大多数陆地植物的根系之间形成的一种互利共生关系。植物给菌根真菌提供碳水化合物；作为回报，菌根真菌能够增强植物对矿质营养元素的吸收。

METHODS: Thirty male SD rats were randomly divided into control group, stress group and NG-nitro-L-arginine methyl ester group. The rat model of water immersion-restraint stress was established. The expression of nNOS in colonic submucous plexus and myenteric plexus in the rats was examined by immuno-histochemical staining and analyzed by computer image analysis system.

SD大鼠30只随机分为对照组，应激组和L-NAME组，采用水浸-束缚应激动物模型，用免疫组织化学ABC法检测nNOS在大鼠结肠黏膜下神经丛和肌间神经丛的表达，应用计算机图像分析系统对其表达进行定量分析。

Under natural conditions and with human activity, the dominance of Oxytropis coerulea become weaker than ever among associations, which reflects a tendency of inverse succession, while those which are less disturbed by human activity show xerosere character because of poor habitat.

在自然条件和人为干扰双重作用下，蓝花棘豆Oxytropis coerulea在群丛中的优势度明显弱化，群丛反映出逆演替趋势，受人为干扰较少的群丛则由于生境条件较差显现旱生演替特征。

The plant species diversity of 9 associations in the Oxytropis coerulea community of mount Wutai was studied by using richness index, Simpson index, Shannon-Weiner index and evenness index, respectively. The results indicated that: The quantity of populations and species in the community have obvious unevenness character, which leads to variation of λ. index and H' index among different associations. R1 and H' increase firstly, and then decline slowly with the increase of elevation, which reach peak value at 2100 while E1 index waves steadily with elevation change.

应用丰富度指数(R1)、Simpson指数、Shannon-Weiner指数和均匀度指数(E1)研究了9个群丛的植物种多样性，结果表明：种群数量及其种群内个体数量具有明显不均匀性，进而导致λ指数和H'指数在不同群丛间的变化，R1、H'指数随海拔高度增加表现为先上升而后缓慢下降，在海拔2100m处达峰值，E1指数则随海拔变化呈现不稳定波动。

Phragmites australis, by TWINSPAN, and the community characteristics of each association were described. The result of the ordination for 41 samples by DCA revealed the relationships between the pattern of these communities and certain environmental factors, especially the moisture in soil.

样方的DCA排序结果较好地反映了植物群丛类型与环境因子，尤其是土壤含水量之间的关系。28种DCA排序结果较好地反映了群丛的生境特征，优势种的分布格局在很大程度上决定着植物群落的分布格局。

Nine of all the 62 patients had been found complications,including hematoma in 3 cases,lymphadenectomy in 2 cases,cervical plexus injury in 2 cases,phrenic nerve injury in 1 case,brachial plexus injury in 1 case and pneumothorax in 1 case.

其中术后伤口血肿形成3例，淋巴漏2例，颈丛神经皮支损伤2例，膈神经损伤1例，臂丛神经损伤1例，气胸1例，所有患者出现并发症后均得到及时的处理。
