方法用Raypex5根尖定位仪对205颗患牙共403个根管进行根管工作长度测量，以此长度进行根管预备充填后拍摄X线片观察根管充填的质量。

Method］ 5 matrices: M1(50% peat + 50% perlite),M2(40% peat + 60% perlite),M3(50% peat + 50% chestnut soil),M4(40% peat + 60% chestnut soil) and M5(100% peat) used for Euonymus fortunei cutting in container were tested and the effect of the different matrices on the rate of callus induction and root growth,the length and number of root,and the growth amount of Euonymus fortunei was investigated.［Results］ The results showed that the best effect on Euonymus fortunei cutting was from the M1,in which,the rate of root growth,callus induction,the length of root and the number of new branch were 87%,88%,68.0 mm and 4.6 branches,respectively.

方法］采用5种基质配比，分别为M1（50%泥炭+50%珍珠岩）、M2（40%泥炭+60%珍珠岩）、M3（50%泥炭+50%栗钙土）、M4（40%泥炭+60%栗钙土）、M5（100%泥炭）对扶芳藤进行容器扦插育苗试验，对不同基质引起的扶芳藤愈伤率、生根率、根长、单株根系数目、新生枝数及新生枝生长量进行调查分析，［结果］结果表明，基质M1中扦插的扶芳藤生根率、愈伤率最高，分别为87%和88%；根长最长，为68.0 mm；平均新生枝数最多，为4.6条，效果最佳。

The mechanisms for the differences among rice cultivars in Cd uptake and translocation There were significant differences in root oxidating abilities and soil redox potential between two typical rice cultivars, Shan you 63 and Wu yun jing 7, that are greatly different in Cd uptake from soil. The root oxidating abilities and soil Eh were accordant with Cd uptake for the cultivars. The difference between the two cultivars in Fe concentrations of root iron plaque was also significant. The cultivar with higher Fe concentrations in root iron plaque absorbed less Cd from soil.

四、水稻不同品种对镉吸收及分配存在差异的生理机理对土壤中Cd吸收能力差异很大的水稻不同品种间，根系氧化力和土壤氧化还原电位有显著差异，品种的根系氧化力和土壤氧化还原电位与该品种对Cd的吸收能力间有很好的一致性；水稻不同品种间，根表铁氧化膜的含铁量有显著差异，根表铁氧化膜含铁量高的品种，对土壤中Cd的吸收能力低；盆栽水分腾发量高及根系伤流液Cd浓度高的品种，吸收积累Cd的能力强。

The shoot formation rate of IBA induced PLBs was high, no matter they were cultured on yam bean or potato homogenate containing media. The 1/4 diluted MS basal salt medium had the best root induction and growth rate. Root cutting affected plantlet height and the number of shoot. However it had no significant influence on root length and number of root.

发根试验中探讨培养基中MS基本盐浓及继代培养时进根处对小苗发根生长之影响，结果显示含有1/4MS基本盐浓之培养基发根最高，而继代时之根处，会影响组培苗地上部之苗长及定芽，但对地下部之根长及根影响并显著。

Results showed that NBPT mixed proportionally with urea increased the soybean root vigor, root nodule number and weight, the root nitrogen fixation activity,and therefore the root growth was increased by a high content of N in the soybean plant.

结果表明，NBPT提高了大豆整个生长期的根系活力，对根瘤固氮酶活性有促进作用，根瘤数量和重量都有增加，因而大豆植株的含氮量也随之增加，根系生长得到促进。

In this study, NBPT mixed proportionally with urea and NBPT without urea were applied to the soybean plants to analyze the effect of NBPT on the soybean root growth in root vigor, root nodule number and weight, and the activity of nitrogen fixation of root nodule.

为探索利用NBPT提高大豆生长发育的途径，对施用NBPT的大豆，利用氧化还原法，乙炔还原法和凯氏定氮法分别测定了大豆根系活性，根瘤固氮活性和植株含氮量，并测定了大豆根瘤的数量和重量。

Root system is sturdy develop, give birth to root nodule closely, the errant bud on its root recovery capability is strong, can make root system spreads to horizontal way.

根系粗壮发达，密生根瘤，其根上的不定芽再生能力强，能使根系向水平方向蔓延。
