  “次生吸器”译为未确定词的双语例句
     At 48h after inoculation with isolate Bai3, the primary hyphae growed from the apex of the appressorium over the surface of the host epidermal cells, and condium developed further into haustoria, at 72h after inoculation. primary hyphae developed into secondary hyphae and formed a hyphal colony with secondary haustoria. The colony began to produced condiophores and condia at 4 days after inoculation.
     在亲和性组合扬158/Bai3中,接种48h后,白粉菌附着胞沿寄主表皮方向长出初生菌丝,分生孢子进一步发展形成吸器,接种72h后,初生菌丝进一步扩展形成次生菌丝,从而形成具有次生吸器的菌落,接种96h后,次生菌丝进一步扩展,形成许多次生吸器

The seedlings from wheat seed coated with seed coating formulation (SCF) NO. 17 containing fungicide triadimenol and other chemicals were inoculated with a virulent race of Puccinia striiformis West. The effects of SCF No. 17 on development of the fungus were examined with electron microscope. The results showed that SCF No. 17 caused a series of changes in the fuagal cell and host cell. The lipid bodies and vacuoles increased in the cytoplasm of hyphae and primary haustoria.

本研究采用电镜技术研究了种衣剂17号对小麦条锈菌发育的影响。观察结果表明,该种衣剂引起病菌和寄主细胞内发生了一系列变化。病菌菌丝和吸器内脂肪粒和液泡明显增加;菌丝壁和吸器壁呈不规则加厚;菌丝分枝处无隔膜产生或隔膜畸形;有的吸器母细胞产生的畸形入侵栓,大都不能穿透寄主细胞壁,初生吸器外间质内沉积有染色较深的物质,次生吸器可产生多个不规则分枝,但不能扩张膨大;菌丝外渗的物质可能引起寄主细胞的坏死;大多数受侵寄主细胞可分泌形成较大的胼胝质,有时寄主细胞分泌的物质可将吸器体完全包围起来。上述结果表明,种衣剂17号不仅可直接作用于条锈菌,而且也可通过影响寄主而间接地影响病菌。

The histopathological features were observed and contents of amino acide in the wheat seedling were determined.The result showed that the rate of primary haustoria of Blumeria graminis f.sp.tritici,the quantity of secondary haustoria and the quantity of conidiophore basal cell of singlespore colony were significantly different between slowmildewing and highly susceptible cultivars,which can be used as the index for identification of the wheat slowmildewing resistance in the seedling stage.The percentage...

The histopathological features were observed and contents of amino acide in the wheat seedling were determined.The result showed that the rate of primary haustoria of Blumeria graminis f.sp.tritici,the quantity of secondary haustoria and the quantity of conidiophore basal cell of singlespore colony were significantly different between slowmildewing and highly susceptible cultivars,which can be used as the index for identification of the wheat slowmildewing resistance in the seedling stage.The percentage of primary papillae and the quantity of secondary appressoria of singlespore colony were not significantly different between slowmildewing and highly susceptible cultivars.All of cultivars tested didnt produce necrotic hypersensitive reaction of cell.The contents of proline and serine of the slowmildewing cultivars in the noinoculated leaves were higher than that of highly susceptible cultivar,the serine content of the slowmildewing cultivars in inoculated leaves were lower than that of highly susceptible cultivar respectively.

对小麦幼苗进行了组织病理学观察和氨基酸测定。结果表明:在初生吸器形成率、单孢菌落未成熟次生吸器数、单孢菌落梗基胞数上,慢粉品种与快病品种之间差异显著(P=0.05),这些指标可作为苗期鉴定慢粉品种的指标;在初生乳突形成率和单孢菌落次生附着胞数上,慢粉品种与快病品种间无显著差异;所有参试品种,都未产生过敏性细胞坏死。未接种叶的脯氨酸和丝氨酸含量,慢病品种高于快病品种;接种叶的丝氨酸含量,慢病品种低于快病品种

Staining effects of uranine and Coomassie brilliant blue R-250 on Blumeria graminis f.sp. tritici was observed. The results showed that uranine staining need only 20 min. of sample treatment, without inhibiting pathogen growth. Uranine was mainly accumulated in the septum and cytoplasm of living pathogen, maintaining brilliant green fluorescence for about 7 min. By use of fluorescence microscopy, the development of the pathogen on the wheat leaves surface could be detected and the dead and alive pathogen could...

Staining effects of uranine and Coomassie brilliant blue R-250 on Blumeria graminis f.sp. tritici was observed. The results showed that uranine staining need only 20 min. of sample treatment, without inhibiting pathogen growth. Uranine was mainly accumulated in the septum and cytoplasm of living pathogen, maintaining brilliant green fluorescence for about 7 min. By use of fluorescence microscopy, the development of the pathogen on the wheat leaves surface could be detected and the dead and alive pathogen could be distinguished. Coomassie brilliant blue R-250 took about 40 min. for treating sample, and the host cell was turned into light blue, and pathogen dark blue. This is a rapid staining method for observing infection structures of B. graminis f.sp. tritici on wheat epidermis or in infected cell, such as primary germtube, appressorial germtube, mature appressoria, pristine haustorium and secondary finger-like haustoria as well as conidia.

比较了荧光素钠和考马斯亮蓝应用于小麦白粉病菌染色的效果。荧光素钠法中样品处理只需20min.左右,具有直接、快速的特点;荧光指示剂对病菌分生孢子萌发及菌丝生长无抑制作用,主要沉集于活菌体的隔膜和细胞质部位,使病菌产生明显的亮绿荧光和清晰的细胞轮廓,亮绿荧光衰退期为7min.;借助荧光显微镜可以观察病菌在小麦叶表的发展过程,区别活菌体和失活菌体。考马斯亮蓝法包括传统的组织学染色步骤,经过改进后的样品处理过程需要40min.左右;染色后使寄主组织呈现淡蓝色,病菌菌体染成深蓝色;该方法可以观察病菌在小麦叶表和被侵染细胞内部发育形成的结构,包括孢子发育形成的初生芽管、附着胞芽管、成熟附着胞以及在寄主细胞内形成的初生吸器原体、成熟的指状体吸器和次生吸器
