用XAD-2型树脂采集荷叶天然香气。以双柱毛细管GC/MS/DS联用法和三柱毛细管保留指数法分离鉴定了87种组分,占总峰面积的93.26％,其中50种组分是用上述两种方法共同确证的,占总峰面积的81.31％。含量较大的组分有顺-3-己烯醇(40.41％);二苯胺(8.35％);长叶烯(5.6％);正己醇(3.65％),苯(3.12％)。     

Rhodanese activity in Lotus corniculatus s.l.

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.     

On the polymorphism of cyanogenesis in Lotus corniculatus L.

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.     

科学的地域建构:社会文化因素及其效应——基于“定性与定量综合集成法”的科学活动中心再阐释

基于"定性与定量综合集成法"对社会文化因素影响科学地域建构表明:文艺、哲学、教育三因素是基础性因素具有"启蒙"作用;经济、技术和科学三者结合性强,经济对于科学的发展可能是刚性的;政治因素对科学发展具有"刺激"或"保障"作用。科学活动的地域建构,最好将这些因素作为一个整体效应来理解。

宋词“莲”之物色美及其艺术表现

莲是受历代文人关注和喜爱的一种名花异卉,也是宋词中十分突出和重要的一种花卉意象。词人对莲的物色美有全面而深刻的体认,从莲的叶、花、柄、莲蓬、莲子、藕的局部特征,到一株莲、一片莲的风姿,从莲的花香,到其叶、柄、藕的香味,从嗅觉到味觉,对不同环境诸如雨中、风里、月下的莲的神态等,都有出彩的描绘。体现出宋人怡情自然、高雅脱俗的生活情趣,显示了宋词独特的艺术魅力。

The cytogenetics of Lotus (Leguminosae)

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.
