Under the condition [0mmol/L,raise in vermiculite] of phosphorus stress, variation in root morphology and biomass among different soybean genotypes at seedling stage were studied, the result shows: At two-leaf age, higher P-efficiency genotypes(K1 and K2) don't develop their potential advantages; at four-leaf age, some characteristics of K1 and K2, such as lateral root number, lateral root length, root absorbent area and dry weight of shoot are all less reduced than those of intermediate P-efficiency genotypes(Z1 and Z2) and of lower P-efficiency genotypes(M1 and M2), and dry weight of root and R/S of higher P-efficiency genotypes are more increased than those of the others.

在磷胁迫[0mmol/L，砂培]条件下，对不同基因型大豆苗期在根系形态、生物量等方面的差异进行了研究，结果表明：磷高效基因型在两叶期并未发挥出其基因型潜力的优势；四叶期，磷高效基因型的侧根数、侧根长、根系吸收面积、茎叶干重等性状的受抑制程度均显著低于磷中、低效基因型，而地下干重、根冠比却受到了较中、低效基因型更强的诱导作用。

At the same time, gene interaction was observed in some of characters, transgressive segregation gene interaction was observed in polygenes controlling length of axial root and thickness of root base （ 1cm）, complementary gene interaction was significantly detected in nodule number of lateral root and dry weight of lateral root and nodule number of lateral root, but not detected or significant in the others.

控制主根长性状的多基因间存在互作，互作方式为重叠作用；控制主根粗（3cm）性状的基因间也存在一定的重叠作用，但是作用不明显；控制其他性状的基因都存在互作，表现为互补作用，但互补作用的强弱有差异。

In nutrient solutions,deoxygenation caused a series of changes in root ana-tomy of some species,such as increased root diameter,root porosity and more developed aerenchyma,inducing a ROL barrier in root basal part and the consequent change of ROL profile.

溶液培养条件下，缺氧胁迫能使植物根的直径增粗，根孔隙度提高，通气组织更加发达，诱导根基部泌氧屏障的生成，使泌氧速率和泌氧方式发生变化。

The results showed that compared with soil culture, the root cap was not obvious with less amyloplast and polysaccharose substance under water culture. The root epidermis under water culture was thinner than that of soil culture, with little root hair or not, in which cortex parenchyma tissue developed with big cell, solution proliferative aerenchyma in intercellular space, and thin cell wall. However, the root cap under soil culture was big, with strong PAS reaction and no aerenchyma tissue.

结果表明：水培后根冠不明显，淀粉体较少，多糖类物质较少而土培根根冠体积较大，淀粉体较多，多糖类物质多，土培根PAS反应强烈；水培根表皮厚度比土培根小，水培根根毛少或退化消失；水培根皮层薄壁组织发达，细胞大型，壁薄，细胞间隙中含有溶生性通气组织，土培根皮层未见通气组织。

In the broad-leaved Korean pine climax forest, the fine root climax production of the community occurs in July and October, but the dominant arboreal species, understory arboreal species and fine roots of grass have a different production dynamics. It is important to sort the fine root species because accurate fine root production sources have a different fine root dynamics.

在原始阔叶红松林中，群落细根的生长高峰发生在7月和10月，但其中主要树种、其他木本和草本的细根有着不同的生长动态，所以在计算细根生产量时应该分类计算，才会得出较为准确的结果。

The results show that soil-root complex still comply with Coulomb's law; root-soil complex cohesion and the incremen in the unit soil content directly proportional relationship, and the root system anchoring role formula is established based on this; Different distribution methods in root has different impact on the shear strength of composite material.

最后，通过有限元分析表明，草根的作用，能够降低浅层土体中的应力水平，即草根能改变浅层土体的应力应变状态；草根增加了浅层土体的粘聚力，对边坡的稳定是有利的。

Methods:Ninetythree patients with root gangrenous perforative appendicitis were treated with laparoscopic appendectomy from Jun.2002 to Dec.2007,and the clinic data were summarized.When dealing with the appendical root,46 cases were used double Endoloop to ligate the appendical root or double titanium clips clipping,23 cases were directly used laparoscopic appendectomy to knot the appendical root,15 cases were used the interrupted suture appendectomy stump and fibrin glue coverage,9 cases of appendical remnant tissue were removed,covered with fibrin glue and placed silica drainge tube.

总结2002年1月至2007年12月应用LA治疗93例坏疽、化脓性阑尾炎合并穿孔患者的临床资料，术中处理阑尾根部时，使用 Endoloop阑尾根部双重套扎或双重钛夹夹闭46例，直接腹腔镜下丝线打结阑尾根部23例，间断缝合阑尾残端加医用生物蛋白胶覆盖15例，清除阑尾残余组织加医用生物蛋白胶覆盖残端，放置硅胶引流管9例。

Similarly, the cotton root-length density reduced gradually from the root axis to both sides of it, and the maximal length density of root was observed at the position of root axis in soil and was diminished by increased dripper discharge.
