菌根

Alternaria-induced necrosis and chlorosis of all leaves were studied in mycorrhizal and non-mycorrhizal plants over time course and at different soil P levels.

长期在菌根和非菌根植物和在不同的土壤P水平上，对所有的由早疫病菌诱导的坏疽和萎黄的叶片进行了研究。

Ectomycorrhizal fungi are most commonly isolated from sporocarp tissue, but can also be isolated from surface sterilized ecotomycorrhizae, sclerotia, rhizomorphs, and in some cases, from sexual spores.

外生菌根菌通常由孢子果组织来分离，但是也可由经表面消毒的菌根、菌核、菌索、及有性孢子来分离。

Some taxon-selective primers that were intended to be specific to fungi and basidiomycetes respectively have been designed and tested to characterize fungal symbionts by amplification of specific sequences in the nuclear ribosomal unit.

大量DNA分析新技术在丛枝菌根真菌的分子遗传、分类鉴定、种间及种内亲缘关系、菌株持久性等方面得到应用，与传统菌根研究方法相比，表现出巨大的优越性。

The fruiting bodies of ectomycorrhizal fungi were abundant and diverse in intact forest dominated by Fagaceae. Only a few species of macrofungal bodies were found in the pine dominated forest and secondary broad-leaved forest and none were seen in grassland during the study.

外生菌根菌子实体在以壳斗科植物为优势种的原生性次生林中较多且种类丰富，在松林和次生阔叶林有少数种类，但次生草坡群落未见有外生菌根菌子实体。

More than 80% terrestrial plants form mutualistic mycorrhizal symbionts with arbuscular mycorrhizal fungi, which change the competitive interaction between plants and mediate their coexistence.

地球上80％以上的陆生植物都可与丛枝菌根真菌(arbuscular mycorrhizal fungi，AMF)形成菌根共生体，菌根可以改变植物之间的竞争关系、调节植物共存。

Great attention has been paid to the mycorrhizal studies over the world because of the wide use of mycorrhizas .

随着人们对菌根认识的逐渐深人，菌根应用越来越广泛，菌根研究也日益引起世界各国的普遍关注。

The apoplasmic charater of ectomycorrhizal roots of Larix seedlings infected with Paxillus involutus was examined using the cathnic colloidal gold. The result showed the density and distribution of anionic binding sites were different in sheath and Hartig net. The negative charger in the outer part of the sheath was slightly low. It increased graduately from outer to inter sheath. The negative charger density rised higher in the inter part of the sheath and then decreased graduatedly from the sheath to Hartig net. This may be related to nutrient uptake and atransport in ectomycorrhizal roots.

利用阳离子胶体金探针研究日本落叶松和卷缘桩菇形成的外生菌根质外体的特性，结果表明，外生菌根质外体负电荷分布是不均一的，在菌套外侧负电荷比较低，向内侧逐渐增高，在靠近单宁层菌套菌丝细胞壁负电荷密度最高，再向内侧过度到哈蒂氏网又呈现出明显逐渐下降的现象，而且在哈蒂氏网负电荷主要分布在植物的细胞壁，真菌菌丝细胞壁负电荷很少。

The mycorrhizal formation,inoculation effectiveness,extraradical fungal biomass and P uptake contribution of six arbuscular mycorrhizal isolates screened from South China,Center China and North China on typical cinnamon soil,brown soil and red soil collected in above three regions were investigated using three-compartment glass-bead culture system associated with maize.

以分离于华北、华中和华南3个生态区及法国引进的丛枝菌根真菌为试验菌株，采用三室根箱培养的方法，研究了它们在华北、华中和华南3种典型土壤—褐土、棕壤和红壤上的菌根形成、接种效应、磷吸收贡献和根外菌物量情况。

Through observing of the ectomycorrhizal exterior forms and tissue sections, we found there were mantle of fungi tissue which enclosed the root, emanating hyphae of the rhizoplane, and the Hartig net which was formed by the hyphae between the epidermal and cortical cells.

035、044、GT005、LH008。通过6种外生菌根及其组织切片的观察，发现菌根根表具有外延菌丝和菌丝套，在细根皮层细胞间形成哈蒂氏网，证明这6种外生菌根真菌与白桦幼苗建立了共生关系。

The recent studies showed that most orchid mycorrhizae belong to Basidiomycota and Deuteromycotina fungi, and some belong to Ascomycota. There are two modes for the formation of orchid mycorrhizae, one is the infection of orchid seeds and the other is the infection of orchid radicles.

目前研究已知，感染兰科植物根部并能与之共生的真菌绝大多数属于担子菌门和半知菌门，也有部分属于子囊菌门；兰科菌根的形成可分为两种情况：一是对兰科植物种子的侵染；二是对成长新根的侵染。

Finally, according to market conditions and market products this article paper analyzes the trends in the development of camera technology, and designs a color night vision camera.

最后根据市场情况和市面上产品的情况分析了摄像机技术的发展趋势，并设计了一款彩色夜视摄像机。

Only person height weeds and the fierce looks stone idles were there.

只有半人深的荒草和龇牙咧嘴的神像。
