The temperature for pathogen sporangium to germinate and to release moving spore is 5~35oC,the optimum temperature is 10~20oC.Under suitable temperature, the sporangium germinate and release moving spore within 2 hours, water film is the essential for sporangi...

霜霉病菌孢子囊萌发释放游动孢子的温度范围为5~35℃,最适为10~20℃,在适宜的温度范围内2小时孢子囊就可释放游动孢子;孢子囊必须在水膜中才能萌发;在供试的碳源中,孢子囊在乳糖液中萌发最好;在供试的氮源中,孢子囊在硝酸铵液中萌发最好;孢子囊萌发的pH值范围为4.5~9.0,最适为8.5。

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%。

In some fungi are also called spores, and is actually produced by the process of sexual sexual spores, such as water mold eggs spores (2N), Rhizopus zygospore (2N), Ascomycetes ascospores, smut basidiospores and so on.

在真菌中有些也称做孢子的,实际上是有性过程所产生的有性孢子,如水霉菌的卵孢子(2N)、根霉的接合孢子(2N)、子囊菌的子囊孢子、担子菌的担孢子等。

The release and survival of ascospores of a UK Sclerotinia sclerotiorum isolate were studied.

人们研究过一种源于英国菌核病的子囊孢子的生存和释放。

18 Days after perithecia appearance was the best time to isolate ascospores, although there were differences between crosses. The highest survival percentage of ascospores could reach up to 85. 5% during this period.

观察发现,虽然不同杂交组合间有一定差异,分离稻瘟病菌子囊孢子的适宜时期,一般在子囊壳开始出现后7~18天之间;在此期间分离出的子囊孢子成活率最高可达85.5%。

At first, optimization for the perfect stage production of M. grisea was investigated in vitro. The number of perithecia and ascospores, the percentage of viable ascospores were markedly increased when juice of mature tomato was used, pH was adjusted around 5. 5 and 0.1%CaCO〓 was added in oatmeal tomato agar medium.

本研究首先选用自然成熟的番茄榨汁和燕麦片作为培养基的主要组分,通过调节培养基pH值在5.5左右并添加0.1%CaCO〓途径优化了稻瘟病菌有性世代形成的条件,显著增加了稻瘟病菌子囊壳形成的数量和子囊孢子的成活率。

Ascospores were released in both saturated air (90–95% rh) and at 65–75% rh.

子囊孢子的释放要同时满足饱和空气(90-95%RH)以及相对湿度为65-75%的条件。
