Sulphur-containing amino acid of transgenic crowtoe plants analysis showed that the content of sulphur-amino acid of transgenic zeolin crowtoe plants was significantly higher than that of the content of the transgenicγ-zein crowtoe plants and non-transgenic crowtoe plants (P.01), but there was no significant difference between the transgenicγ-zein plants and non-transgenic plants.

含硫氨基酸数据分析表明,转zeolin基因百脉根植株含硫氨基酸含量极显著高于转γ-zein基因百脉根植株和非转基因百脉根植株的含量(P.01),但转γ-zein基因植株与非转基因植株间差异不显著。

In order to remove different concentrations of suspended sediment, a serial connected system of emerging plants, floating-leaved plants and submerged plants based on spatial distribution of natural water body was constructed by aquatic marcrophytes, such as Cyperus alternifolius, Acorus tatarinowii, Trapa japonica, Ceratophyllum demersum, Hydrilla verticillata and Vallisneria spiralis. Sandy water then flew through emerging plants, floating-leaved plants and submerged plants.

根据自然水体湿生植物、浮叶植物以及沉水植物的空间分布规律,利用风车草、石菖蒲、菱、金鱼藻、轮叶黑藻和苦草等水生植物构建由挺水植物、浮叶植物到沉水植物的串联系统,含沙水依次流经挺水植物、浮叶植物和沉水植物,测定各级植物对泥沙的去除效果。

Based on the evaluation system, the plants whose relative remediation age was between 0~10 years were named as"Hyperaccumulator"and those between 10 ~ 50 years were named as"Accumulator".7 In the experiments six kinds of substrates were mixed with different solid wastes and the absorption and enrichment of plants on heavy metal Cd was studied. The results showed that relative remediation age was an ideal index to evaluate the capability of the phytoremediation on heavy metals, because it took into account more factors which affected the absorption evaluation effects than others, such as the heavy metal content and the biomass of the over-ground part of plants, the heavy metal content and the whole gross in substrates, harvesting frequency of plants and the environment standard of heavy metal. This made relative remediation age be suitable to the sorption capability evaluation of not only different plants on one heavy metal but also one plant on different heavy metals.8 It can be drawn from the relative remediation age of heavy metal Cd that the absorption capability of different plants was not same.

以相对修复年限为评价指标定义相对修复年限为0-10年的植物为&超富集植物&,10-50年的植物为&富集植物&。7在由不同废弃物按一定的比例混合配制的六种土地复垦基质上,系统地研究了几种植物对重金属镉的吸收和富集情况,结果表明,相对修复年限既适用于不同植物对同一种重金属元素的吸收能力的评价,又适用于同一植物对不同重金属元素的吸收能力的评价,是衡量重金属元素植物修复效果的理想指标。8从不同植物对同一基质重金属镉的吸收和富集能力看,不论是经过多年种植的基质,还是第一次种植的基质,小白菜和油菜都是相对理想的植物;而黑麦草、高羊茅和苜蓿的吸收效果并不理想。

Results showed that the root colonization rate of S. gracilis (62.2%) was higher than that of A. conyzoides (36.5%) and P.notatum (37.3%).The arbuscule percentage showed a similar pattern. Although the biomass and P content in the shoots of the three grass species were comparable, P content in S. gracilis roots was higher than that in A. conyzoides and P. notatum roots. The species richness and hyphal density in the rhizosphere soil of S. gracilis plants were less than those of A. conyzoides and P. notatum plants, while the spore density was highest for A. conyzoides and lowest for P. notatum. Diversity index of the native AM fungi in the rhizosphere soil of P. notatum plants was slightly higher than those of S. gracilis and A. conyzoides plants. PCRDGGE analysis was consistent with the morphological results.

结果表明,柱花草根系的侵染率(62.2%)显著高于百喜草(36.5%)和藿香蓟(37.3%),丛枝率有相似的趋势;3种草地上部的生物量和含磷量没有差异,但是柱花草根系含磷量显著高于百喜草和藿香蓟;柱花草根际土壤中AM真菌的菌种丰度和菌丝密度均小于百喜草和藿香蓟,但是孢子密度大于藿香蓟而小于百喜草;藿香蓟根际土著AM真菌群落的多样性指数略高于柱花草和百喜草;PCR-DGGE分析结果与之吻合。

In concrete research, the dissertation concludes two styles of the motif: the practical and the idealistic, six structures of the motif: the returnee's disillusion, the returnee meeting old friends, the returnee putting ideal into practice, the returnee's retirement, the returnee's revenge and the returnee' individual struggle, two narrative sequences of the motif:"leave the native place"——"returning to native place"——("leave the native place"), and illusion——disillusion, and three basic subjects of the motif: the realistic view in troublous time, illustration of Chinese experience in cultural "change" and "installation", and modern moral: the imagination of native place and the identity.
