核盘菌病

The results suggested that the hypovir-ulence - associated genetic elements existed in the cells of isolate Ep- 1PN unequally, andsome cells were shortage of the hypovirulence- associated genetic elements.1572 sexual progenies of isolate Ep- 1PN were obtained through single- ascospore -isolation from seven apothecia.

本文对核盘菌Ep-1PN菌株的弱毒特性及其相关特性的遗传特点进行了分析，并评估了Ep-1PN菌株及其弱毒因子防治菌核病的生防潜能，现将结果报道如下

Infection by S. sclerotiorum causes serious damage to oilseed rape, soybean, sunflower and the mustard family vegetables. Because S.

草酸是核盘菌致病过程的决定因子，核盘菌在油菜、大豆、向日葵与十字花科蔬菜等植物上引起严重的菌核病。

In order to study on the fast,simple and efficacious method of forecast the sclerotinia stem rot.

为了探索预测油菜菌核病发生情况的快速、简单、有效的方法；此研究采用检测被核盘菌子囊孢子感染的油菜花瓣数量来预测预报菌核病可能发生严重度程度，实验采用添加了两种不同pH指示剂的改良型Steadman's培养基在室温下培养在油菜花期(3月下旬～4月中旬)每天采自2块试验田的新鲜花瓣，如果花瓣被病原菌子囊孢子感染，接种培养后培养基颜色发生改变，统计被感染的花瓣数；结果表明：除1天在一块田没有检测到被子囊孢子感染的花瓣外，油菜整个花期都有被感染的花瓣出现，但初花期被感染的花瓣较少，而盛花期和终花期被感染的花瓣较多，第一块田被感染的花瓣数在两种培养基上出现的百分率分别为32.0%和40.2%，第二块田分别为27.3%和35.7%。

An improvement on mass production of apothecia of Sclerotinia sclerotiorum, a causal agent of sclerotinia stem rot of oilseed rape, was achieved by screening suitalbe strains and evaluating factors affecting carpogenic germination for this fungus.

核盘菌引起包括油菜在内的多种经济作物的菌核病。为筛选抗菌核病的作物品种及探讨防治该病的其它途径，获得足够的子囊孢子是极其重要的技术环节。

Coniothyrium minitans, an important sclerotial mycoparasite of Sclerotinia sclerotiorum with worldwide distribution, has great potential for biological control of plant diseases caused by S. sclerotiorum and other Sclerotinia spp.

盾壳霉是引起作物菌核病的核盘菌的重要寄生真菌，在世界范围内广泛存在，是菌核病的一种重要生防菌。

A primary crop where myceliogenic germination plays a major role in the disease cycle is in Sclerotinia wilt of sunflower.

在向日葵核盘菌萎焉病的疾病周期中菌丝体遗传扮演着重要的角色。

Most other Sclerotinia or white mold diseases, such as on dry beans, soybean, canola and sunflower head rot are initiated by and infection of above ground plants parts by ascospores.

大多数其他的核盘菌或白霉菌，干豆、大豆、向日葵等作物的热腐病都是由于子蘘孢子浸染植株的地上部分所致。

This essay chooses the study aim from biology teachers in middle school in Shi Jiazhuang which tells us that most of the middle school biology teachers in Shi Jiazhuang have the"burnout", lower successfulness, individualize.

本文选取石家庄市初中生物教师作为研究对象，运用问卷调查的方法对石家庄市初中生物教师职业倦怠的现状进行调查，调查结果发现，石家庄市初中生物教师这一群体普遍存在职业倦怠，情感枯竭程度偏高，成就感偏低，去个性化程度最为严重。
