细根

This study is focused on the vertical distribution, production and turnover of the fine roots in a broad-leaved and Korean pine climax forest of the Changbai Mountain Reserve.

采用连续土钻分层取样法，对长白山自然保护区中原始阔叶红松林细根的垂直分布、生长和周转进行了研究。

Along with the Korean pine and broad-leaved climax forest succession (a 20 yr Populus davidiana and Betula platyphylla secondary forest, an 80 yr Populus davidiana and Betula platyphylla secondary forest and the Korean pine and broad-leaved climax forest), the peak production of fine root is in early summer and autumn.

在原始阔叶红松林的演替过程中（白桦山杨幼林—白桦山杨成熟林—阔叶红松林），细根生长的季节变化特征是生长顶峰出现在初夏和秋季。

Curve peaks of live fine root biomass occur in Jan. and July, while that for dead fine root occur in March and July.

用试验期间不同时间数据拟合得到木麻黄细根分解回归方程：x/x0=1.06e(上标-0.0014t)。

Trees, erect or scandent shrubs, lianas, evergreen or deciduous; stems sometimes producing rootlets Euonymus spp.

乔木，直立或攀缘灌木，藤本植物，常绿或落叶的；茎有时生产细根（Euonymus spp。

Second axis reflected variation in seed mass and fine root morphology. Plants at the positive endof this spectrum were plants with large seeds and low specific root length.

第二轴反映了种子重量和细根形态的变异，在谱的正的这一端的物种具有大的种子低的比根长。

Rhizome procumbent, slender and long, yellow-brown to whitish, internodes longer, with scattered branched rootlets and nodes

Big bluestem persists from year to year, spreading by seed and rhizome, creating an underground web of coarse roots near the surface as well as fine root fibers that may reach eight feet deep where the soil allows.

大白羊坚持每年由种子、根茎蔓延，创造一个地下网站根粗面附近细根纤维以及可能达到八英尺(2米)深的土壤允许。

Herbs annual with fibrous rootlets or perennial with short rhizomes.

一年生草本具纤维状的细根或多年生植物的具短根状茎。

Rhizomes long, prostrate, nodes with rootlets and scalelike leaves.

根状茎长，匍匐，节具细根和鳞片状叶。

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。
