本文系统探讨了土壤中微菌核或孢子受寄主根系分泌物的刺激，开始萌发、产生的菌丝在寄主根表面定殖、穿过表皮、在皮层中发生及在寄主体内扩展和症状形成等黄萎病菌侵染棉花的过程，阐述了寄主植物形成多级防御反应阻击病原菌的入侵。

All of fractionated root exudates inhibited the growth of tobacco seedlings.

此外，酸溶性和碱溶性的根系分泌物对株高有增加的趋势，原因有待进一步的研究。

In details, the strongest inhabitation to the shoot growth was observed when neutral soluble fractionates were supplied. The shoot biomass with neutral soluble fractionates added was decreased by 10.52% over the blank control, resulting in obvious increase of root: shoot ratio. It suggests that the root exudates would be self-poisonous. Besides, both acid and alkaline soluble fractionates exhibited the trend to increase the stem height and it is necessary to exploit the reasons.

在培养液中，分别加入分组的烤烟根系分泌物，均显著降低根系对NO_3~-、H_2PO_4~-、K~+离子的吸收和根系活力，推测根系分泌物中产生抑制作用的物质可作用在相当宽的pH范围；其中，碱溶性组分对H_2PO_4~-、酸溶性组分对K~+、中性组分对NO_3的吸收和根系活力的抑制作用较强，推测在烤烟根系分泌物中，可能存在多种抑制烤烟生K和养分吸收的化学物质；另外，抑制作用随着根系分泌物浓度的增加而增强。

Bt toxin from Bt crops is introduced into soil primarily in root exudates and by incorporation of crop residues after harvest of the crop, with probably some input from pollen during tasseling, which probably have an effect on soil specific organisms, biodiversity and the functions of soil ecosystem.

而加有转Bt基因玉米农大61秸秆的土壤和加有常规玉米农大3138秸秆的土壤相比，土壤脱氢酶活性和土壤呼吸作用强度在秸秆分解期间都没有显著差异；秸秆分解了30d、45d、60d 时，显著提高了土壤蔗糖酶活性；分解了45d和90d时，显著提高了土壤酸性磷酸酶活性；30d时显著增加了土壤脲酶活性，而在45d时则显著降低了土壤脲酶活性；分解45d、60d、90d时显著降低了土壤蛋白酶活性。

The results showed that the sheep had fibrinous pneumonia and lymphocyte interstitial pneumonia, which were typical pathologic changes of this disease. Remarkable changes were observed in the lung: fibrinous exudates, infiltration of inflammatory cells, pleura thickening, interstitial edema, hemorrhage and formation of thrombiand lymph clot. The heart, liver and kidney had different degeneration degree. Reactive hyperplasia presented in bronchales lymphonodi.

结果发现该病例具有胸膜肺炎的典型病理变化，呈现纤维素性肺炎和淋巴细胞性间质肺炎，纤维素性物质的渗出和炎性细胞的浸润很明显，肺胸膜增厚，同时在肺间质还可见水肿、出血、血栓和淋巴栓的形成；另外心、肝、肾也均有不同程度的变性，淋巴结呈反应性增生。

Results: Pulmonary candidiasis model were confirmed in 13 rabbits. The early CT appearance of pulmonary candidiasis was found from the second day to the tenth day after inoculation. We found consolidation in 10 cases, including 6 sublobe consolidation (intra-alveolar exudates) and 4 lobe or section consolidation (pulmonary infarct or hemorrhage).

结果：成功建立13例兔肺念珠菌病模型，首次CT阳性表现出现于接种后2~10 d，包括实变影10例：其中小叶性分布6例，病理表现为肺泡炎性渗出；叶段性分布4例，病理表现为肺组织坏死或出血性渗出。

Culture medium, water volume, root exudates of different crops, temperature, illumination affecting germination conditions of oospores of Phytophthora sojae studied in this reasch and compared the difference of germination of oospores of different race of Phytophthora sojae, filtrated the higher germination rate of strain and suitbable conditions combination of germination of oospores; The pure-line(Race 1) in virulence was obtained through isolation and culture and virulence identify of the second generation. The pure-line was analyzed by molecule method of ISSR. The results were summarized as follows:There was quite difference of germination rate of oospores on different culture medium.

本文测定了不同培养基、水量、农作物根渗出液、温度、光照对大豆疫霉菌卵孢子萌发影响，比较了大豆疫霉菌株间卵孢子萌发的差异，筛选出萌发率较高的菌株和适于卵孢子萌发的条什组合；通过继代单卵孢株分离培养和毒性鉴定，建立了大豆疫霉菌单卵孢株毒性纯系，并分析了单卵孢株毒性纯系后代群体ISSR分子指纹，结果如下： 1。
