为探索离子注入技术新的应用,采用原子荧光光谱法、原子吸收光谱法和电感耦合等离子发射光谱法对离子注入选育莲的重金属元素和矿质元素吸收量进行了分析.结果表明,尽管同种重金属或者矿质元素吸收量在两个品种"京广1号"和"京广2号"间的变化并不一致,但是部分重金属元素与矿质元素的吸收量得到提高.这说明离子注入诱变能够通过提高植物的重金属吸收量而用于重金属污染的植物修复,离子注入诱变也能改善植物的矿质元素吸收而提高其营养价值.该研究为拓展离子注入技术的应用进行了有益的探索. 相似文献

《金瓶梅》妻妾群像中的三个典型人物吴月娘、潘金莲、李瓶儿游走在否定主义美学的框架之内,体现出一种审丑的美学视角,三个人物的贪、嗔、痴所昭示出的丑怪的写实主义以及价值观层面的放纵狂欢,具有强大的嘲讽力量,营造出小说自身特有的"道德秩序"。 相似文献

Rhodanese (EC 2.8.1.1) is a sulphurtransferase which catalyses in vitro the formation of thiocyanate from cyanide and thiosulphate or some other sulphur donor. One proposed function of this multifunctional enzyme in vivo is detoxification of cyanide. Lotus corniculatus s.l. is genetically polymorphic for cyanogenesis. Here we present the first investigation of such a polymorphic species group for its rhodanese content. Enzymatic thiocyanate formation was easily detected in the leaves of Lotus alpinus and L. corniculatus from various natural habitats in Switzerland. All samples taken from these two species were found to contain a higher level of rhodanese activity than samples from the leaves of the six cultivated higher plants examined. Most interestingly, the differences observed within the Lotus species appear to be correlated with the polymorphism of cyanogenesis: cyanogenic plants AcLi showed much higher rhodanese activities than the acyanogenic types Acli and acLi. This correlation suggests that rhodanese provides a mechanism to detoxify cyanide in cyanogenic plants. 相似文献

Chromosome numbers for 108 species of the genus Lotus (Leguminosae) are now known. This represents an increase of 32 new species which have been reported since a chromosome atlas for Lotus was published in 1965. At this rate, with just over one chromosome number being reported for a new species per year, it will require almost a century for the chromosome numbers to be determined for all of the species in the genus. A review of the cytogenetic features which have been observed in the genus through karyotype analyses, chromosome banding, Feulgen cytophotometry, anther culture, HCN reaction and interspecific hybridization is presented. These include cytomixis and B chromosomes (both found in hybrids of diploid species in the L. corniculatus group when L. alpinus was one of the parents), desynapsis, binucleate cell formation, polytene chromosomes in suspensor cells and trisomics in L. pedunculatus. There has been a reduction of HCN content in the species with evolutionary development which is correlated with basic chromosome number and geographic distribution. Classical karyotype analyses may not be a suitable method to investigate the parentage of L. corniculatus because of the chromosomal repatterning which has occurred during the evolutionary development of the closely related diploid species. 相似文献

Most populations of the legume Lotus corniculatus are polymorphic for the characters of leaf cyanogenesis and petal cyanogenesis. The distribution of these phenotypes was investigated in a section of chalk quarry where the vegetation ranged from pioneer species growing on almost bare chalk through to a mature grassland assemblage. The vegetation surrounding randomly chosen L. corniculatus individuals was recorded and this information was used to compare the environments in which the different phenotypes were growing. Leaf cyanogenic plants were found to occur at higher frequencies in grassland areas than in the more open conditions typical of earlier stages in the succession at the quarry. Factors that may be responsible for the distribution of the phenotypes are discussed. 相似文献

南阳市博物馆现存一方宋崇宁四年(1105年)丕师塔记碑。此塔记为南阳县崇胜寺毗卢院住持僧惠海为其师前住持宗丕撰写的塔记铭文。塔记系前人草书诗文碑碣改制而成。同时出土的还有一方《住持僧惠海塔铭》,该塔铭也是前人碑刻改制,背面为汉代持笏门吏画像石,两方铭文碑皆是一石二用,为我们提供了更为丰富的资料。本文试通过对塔记铭文的考释,了解宋代佛教对南阳地方的影响以及前人的书法艺术等。 相似文献
