(1) In the sorption kinetics experiment, Cu2+ sorptions by Ceratophyllum demersum, Myriophyllum triphyllum and Hydrilla verticillata respectively, all reached balance within 35mins, all of the test results of sorption kinetics recommended the pseudo second-order equation and indicated that this kind of sorption was a complicated process of simultaneous actions of many reactions. The test results of thermodynamic sorption fitted with Langmuir model better than Freundlich model, and the maximum sorption quantites were 13.12, 20.12, 7.79mg/g, respectively,In the desorption test, the desorption rates of each plants were all below 1%, indicating strong sorption-holding action of these submersed mcrophytes on Cu2+.

通过上述研究，得到以下结论： 1、狐尾藻、金鱼藻、黑藻在对铜离子的吸附动力学实验中，均在35min内达到吸附平衡，分别用一级动力学方程和伪二级动力学方程拟合，结果均为用伪二级动力学方程拟合效果较好，表明该吸附为多种反应同时作用的复杂过程；在热力学实验中，三种植物的吸附曲线都能较好的用Langmuir曲线拟合，其拟合最大吸附量分别为13.12、20.12、7.79 mg/g；在解吸实验中，三种植物的解吸率都较低，说明对铜离子都有较好的吸持能力。

Wanfenghu reservoir has been polluted seriously, and waters are in a severe eutrophication condition. Whether physico-chemical indexes or biological indexes appraisal, it proved that the water quality of Wanfenghu is between IV-V. Wanfenghu contains high TN and TP which are 5 to 6 times of the national standard content, and the quantities construction of phytoplankton communities is deeply disequilibrium, the Cyanophyta and Charophyta occupying overwhelming

万峰湖水库已经受到了严重污染，水体处于严重富营养化状态，其水体中的溶解氧的三季变化范围在2.92-5.3mg·L之间、化学耗氧量三季平均值为34.77 mg·L~(-1)、总氮三季平均值为2.5 mg·L~(-1)、总磷的三季平均值为0.35 mg·L~(-1)、叶绿素a含量的三季平均值为23.64 mg·m~(-3)，以上各指标表明万峰湖水库水体处于Ⅳ-Ⅴ类水质；无论从浮游植物的群落数量上还是浮游植物种类组成上看，蓝藻和绿藻都占绝对优势，而其它各种藻类极少，是典型的蓝-绿藻型水

In the CO_2 source area, phytoplankton abundance was low and zooplankton mainly belonged to true estuary and estuary marine communities; while in the CO_2 sink area, phytoplankton was high and zooplankton mainly belonged to euryhaline marine communities.

在枯水季节，长江口海域由低盐区大气二氧化碳的强源逐渐过渡到高盐区的弱汇，咸淡水的混合在一定程度上决定了该区域碳源汇的格局；二氧化碳源区，浮游植物的丰度低，浮游动物主要是纯河口类群和河口性海洋类群，而汇区，浮游植物的丰度高，浮游动物主要是广盐性海洋类群。

本文拟在评述近年来禾本利植物组织培养(主要指胚胎培养、器官培养、细胞培养和原生质体培养)的理论性研究和应用性研究的进展，并重点描述和讨沦在应用上较为成熟和有发展前景的几个领域的发展现状以及利用禾本科植物的组织培养技术而进行的基因转移技术的概况。

At the contralateral side, an ischiac bone graft (baseline 3 4 0.87) was transplanted. The healing period was 5 months. Group A11: The animals were treated in the same manner as in Group A5 with the difference that the healing period was 11 months. Group B5: The animals were treated in the same manner as in Group A5 with the difference that an e-PTFE membrane was adapted oer the bone graft on each side of the jaw.

愈合时间为5个月。A11组：用与A5组相同的方法处理小鼠，愈合时间为11个月。B5组：处理小鼠的方法与A5组相同，在每侧颌骨的骨移植物上方各置一片e-PTFE膜。B11组：实验方法与B5组相同，但在骨移植5月后，进行第二次手术取出生物膜，愈合时间为11个月。z在下颌骨骨量增加后，分别于第5个月处死A5组及B5组的小鼠，第11月处死A11组及B11组的小鼠，取下颌骨标本，体式显微镜测量骨移植物的宽度、长度及高度。

Chapter 5: The simultaneous determination of 20-hydroxy ecdysone, 3, 7-dimethoxy-quercetin, acteoside and rutin in the mixture of leaf and stem, and the flower of Lamium maculatum has been investigated by capillary zone electrophoresis for the first time.

所建立的毛细管区带电泳新方法简单、快速，可有效地分析短腺小米草的茎及花中的三种活性成分，该方法不仅可以用于分析短腺小米草植物的这些活性成分，而且对其他小米草属植物中这些活性成分的初期研究也具有重要的参考价值。

Statistics show that Mahonia plant has high genetic diversity, and the distance of gene of same species with different place of origin is markedly smaller than that of different species. The species can be identified by comparing the distance of gene between populations with that of database.

统计结果显示：十大功劳属植物具有很高的遗传多态性，在研究的30个随机引物中，多态性比率为95％；不同产地的同种植物的遗传距离明显小于不同种；在应用中可望对待鉴定材料进行相同引物的扩增，引入数据库，通过计算样品与数据库标准样品的遗传距离来对待测样品进行鉴别，或直接通过聚类来确定其归属。

The result showed that the polarization of populations and gene fluxes are different in different species. The polarization and gene fluxes of populations of 3 Nitavias are lower except N. sphaerocarpa. The heredity coherence of each population is change from 0.8561 to 0.9694. The polarization in the populations is low, and they have the together ancestor. This is similar to morphology and cytology result, so RAPD is a useful supple mentary method in assessing genetic relationship among Nitraria species.

结果表明：白刺属植物的遗传分化程度和基因流因种而异，除球果白刺以外，其余3种白刺的种群间有很大的基因流，其遗传一致度在0.8561~0.9694之间，而种间遗传分化程度较低，故4种白刺有着相近的祖先，这与形态学和细胞学的分析结果一致，说明RAPD分析方法可从分子生物学角度为白刺属植物的系统学分类提供更为有利和可靠的证据。

All of these had shown that the induced resistance could be transmitted.Oligosaccharides had not shown any direct activity against Puccinia striifomis in vitro. This suggests that Oligosaccharides can elicit resistance to diseases of wheat, and are different from common pesticides.

不同浓度(25ppm、50ppm、100ppm)的5号提取物的体外抑菌试验表明，低聚糖对条锈菌没有明显的抑制作用，说明低聚糖不具有直接杀菌或抑菌作用，使小麦产生抗锈性的原因在于诱发寄主植物的抗病潜能，使植物本身产生对病原菌的抗性，这与普通杀菌剂显然不同。

Study of the systematic significance of some pollen characters revealed that the systematic position of these five Salsola species were analyzed based on the pollen morphology. Mover, the relationship between the number of the aperture and systematic position of species was discussed.

同时，研究从孢粉学角度初步分析了该属植物的系统演化关系，孢粉学特征揭示的系统演化关系与前人基于外部形态特征建立的猪毛菜属分组演化系统相一致，此外，还对五种植物的花粉萌发孔数量与其系统进化地位的关系进行了初步的探讨。
