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%。

The main results were as follows:①The genomic DNA extraction method from TCK/TCT teliospore was established, which include cell wall lysis of teliospore by alkali solution, destroying teliospore cell wall for releasing nucleic acid from cytoplasma membrain and elimination of the PCR inhibitors such as pigments or polyphenols component.

论文主要研究结果如下：①优化了碱裂解法破冬孢子外壁-CTAB破坏原生质体，释放核酸-微量DNA过滤柱去除色素、多酚等PCR抑制物质的TCK/TCT冬孢子提取方法，排除了冬孢子细胞壁难破DNA难以提取，三甲胺、色素等PCR抑制物质导致假阴性的难题，采用此方法提取的腥黑穗菌DNA完全适用于PCR扩增。

The observation showed that sterile plants and fertile plants in the pollen mother cell stage is not very different, when microspore mother cells of male sterile plants enter meiosis period, it could form normal tetrad cell , tetrad cell is normal in early development stage, In the uninucleate microspore stage , tapetal cells were vacuolization, the microspores were extruded to the middle by tapetal cells.

本研究利用石蜡切片法，结合光学显微镜技术对樱桃萝卜核质互作雄性不育系的不育株和对应保持系可育株的花药发育过程进行细胞形态学观察，观察结果表明：不育株与可育株在花粉母细胞时期差别不大，不育株的花药小孢子母细胞进入减数分裂期后，可以正常的形成四分体，四分体前期发育正常，而在单核小孢子期绒毡层细胞出现液泡化，绒毡层细胞向中间挤压小孢子。

Besides,interaction of preinvasion of Phytophthora in festans and variousplants was studied by using modified cellulose membrane technique.Potato tuberand leaf promoted both the zoospore germination and appressorium formation,or-ange fruit only promoted the zoospore germination and no effect on appressoriumformation.While onion bulb inhibited the both zoospore germination and appresso-rium formation.

此外，本文利用改进的纤维素膜技术研究了致病疫霉侵入前与15种不同植物之间的相互作用，明确马铃薯块茎和叶片对致病疫霉游动孢子萌发、附着胞形成和侵入丝形成均有促进作用，日本桔果实只对游动孢子萌发有促进作用，对附着胞形成无明显影响，葱和洋葱鳞茎则对游动孢子萌发和附着胞形成均有明显的抑制作用。

We examined the infection of Paecilomyces fumosoroseus via electron microscopy scan and pathogenicity of P. fumosoroseus conidia powder, conidia suspension liquid and conidia broth. Results show more conidia in acanthoid surface topography than in spinous surface topography.
