内生的

The influence factors are divided into endogenous and exogenous source according to the process control factors. The endogenous source includes: the level of materials safety, the level of adminicle use safety, the level of environmental hygiene management and the level of processing technology safety management.The exogenous source includes the level of national supervision, the level of consumer food safety consciousness and the level of agricultural product processing development. Every aspect includes various factors.

However, the area is less studied than other areas of endophyteresearch world wide. Therefore, a series of experiments were carried out in laboratory,glasshouse and field to compare the responses of endophyte infected plants andendophyte free plants of perennial ryegrass varieties to 10 fungal pathogensisolated from turf type ryegrass in Lanzhou. The pathogens used in the experimentswere Alternaria alternata、Bipolaris sorokiniana、Fusarium avenaceum、Curvularialunata、Ascochyta leptospora、Fusarium acuminatum、Fusarium chlamydosporum、Fusarium oxysporum、Fusarium solani and Gliocladium roseum. In addition, someprotective enzymes activity and alkaloids contents of E+ and E- plants were measuredand LpsA gene of the common strain - Lp19 and mutant strain -AR1 of Neotyphodiumlolii were sequenced to identify their ...

本研究在初步明确兰州市坪用黑麦草内生真菌及其病原真菌多样性的基础上，在实验室、温室和田间开展了系列研究，比较了带内生真菌和不带内生真菌的黑麦草在离体和整株条件下对细交链孢、离蠕孢、燕麦镰孢、新月弯孢、小孢壳二孢、锐顶镰孢、厚垣镰孢、尖镰孢、腐皮镰孢和粉红粘帚霉等10种病原真菌的抗病性，测定了E+和E-植株数种保护酶活性及其生物碱含量的变化。

The primary studies on insecticidical and fungicidical components of endophytic fungus in Celastrus angulatus have been carried out from September, 2000 to June, 2002.The results are as follows: Taking PDA and Czapek as separating culture medium, 39 strains of endophytic fungus were separated from the bark, phloem and xylem of the root and twig of Celastrus angulatus.

作者于2000年9月至2002年6月对杀虫植物苦皮藤中内生真菌的杀虫杀菌活性物质进行了初步的研究，取得了以下结果：采用常规的内生真菌分离方法，以马铃薯葡萄糖培养基、Czapek培养基为分离用培养基，从苦皮藤根和侧枝的表皮、韧皮部和木质部中分离得到39株内生真菌。

Temporally, rhizobium abundance in root and pericarp is obviously higher at pod-bearing stage than any other growth stage. Rhizobium abundance in various floral organs rapidly increases after pollination. During ovary-to-legume germinative process, rhizobium abundance in ovary wall and ovule increases logarithmically. Endogenous rhizobia are found in ovule only after fertilization, and rhizobium abundance in young seeds is higher than in fertilized ovule. This implies that endogenous rhizobia can be transported and colonized in early germinated seedlings.

在时间上，结荚期根、荚果皮内的根瘤菌数量明显高于其他时期；花内各器官在授粉后根瘤菌数量迅速增加；由子房向荚果发育的过程中，子房壁和胚珠内的根瘤菌数量随时间呈对数增长；胚珠在受精后即存在有内生根瘤菌，并且幼嫩种子内生根瘤菌数量远高于受精胚珠，证明内生根瘤菌能被转运并定殖在发育早期的种子中。

The results showed that 9 strains presented cytotoxic activities to at least one of the tested tumor cells, five strains exhibited strong antimicrobial activity against Staphylococcus aureus, one strain had inhibitory effect on Phytophthora parasitica.

结果显示，有9株内生真菌至少对一种指示瘤株具有细胞毒活性， 5株内生真菌对金黄色葡萄球菌有较强的抑菌活性， 1株内生真菌对辣椒疫霉有抑制作用。
