与perithecia相关的网络例句 [注：此内容来源于网络，仅供参考]

Furtherly, crosses were made among fertile isolates from rice plants in Jiangsu. Only 6 of 25 crosses produced perithecia and asci, but no ascospore produced. This suggest that the frequency of sexual stage occurrence of Magnaporthe grisea was very low in the rice field in Jiangsu.

用江苏省稻瘟病菌的可育菌株进行互交，25个组合中只有6个组合能产生子囊壳和子囊，但均不产生子囊孢子，提示江苏省稻瘟病菌在田间产生健康有性后代的几率不大。

The hymenium may be directly exposed to the air, as in the gills of the mushroom or may open into a flask-shaped cavity, as in the perithecia of certain ascomycetes.

子实层可能直接暴露于空气，像蘑菇的菌褶，也可能似瓶状开口，如某些子囊菌的子囊壳。

The nitrate non-utilizing mutantas an another added genetic marker was used to select the out-crossed perithecium from self-crossed perithecia. Seven crosses were tested in all, including cross between S×S, MR ×S, MR×MR,HR ×S, as well as HR ×MR. The results showed that no recombinant phenotype was found among all progeny of seven crosses. Progeny segregation of crosses between the parents with different sensitive levels (i.e. MR×S, HR×S,HR×MR) clearly fit a 1:1 ratio of two parental phenotypes, and no segregation was found in the crosses of S×S and MR × MR.

从25个敏感菌株和31个抗性菌株中随机挑选了2个S、3个MR和1个HR，并以硝酸盐营养缺陷型突变体作为另一个遗传标记，按照S×S、MR×MR、MR×S、HR×S、HR×MR等共设计了7个杂交组合，对各杂交后代对多菌灵的敏感性测试发现，在所有杂交后代中均未出现除双亲表现型以外的重组型个体，MR×S、HR×S及HR×MR的杂交后代出现了1∶1的分离比例。

Most field isolates are self-fertile, producing many fruiting bodies called perithecia on the surface of the substrate or in culture.

大多数田间菌株是自交能孕的，在基质或培养物的表面上产生许多子实体称子囊壳。

And R8, stromata produced by the plant R3 and R8 in field;+= viable ascospores produced;= perithecia barren;—= no

上产生的子座；+=生成可育的子囊孢子；=生成子囊壳但败育；—=没有反应；空白=未做。
