植物形态学

On the base of classification of morphology, we studied morphology, cytology and molecular biology of Lilium sulphureum Baker apud Hook. f. in Yunnan By principles of population biology. We synthetically discussed intraspecific differentiation and evolution, from four biotic levels of population, individual, cell and gene.

本文在形态分类的基础上，根据居群生物学的原理和方法，对淡黄花百合的形态学、细胞学、分子生物学进行了研究，从居群、个体、细胞和基因四个层次综合探讨了该种植物的种内分化与进化。

This isolation may have been an important factor in the development of the morphological and genetic variation among pitcher plants in New Caledonia.

这种隔离可能是新苏格兰地区猪笼草植物在形态学和遗传变异发展中的一个重要因素。

In conclusion, a comprehensive analysis of water lilies based on morphological and molecular data was performed, showing the phylogenetic relationships among the 10 genera and providing new evidence for classification at family level. The specific and infraspecific relationships within the genus Nymphaea were revealed using the ITS sequences, providing a new approach to germplasm identification and phylogenetic analysis of water lilies. The investigation of invasive fanwort in China may also provide a sound basis of its ecological studies.

总之，本文以国内外长期研究为基础进行了综合定量的形态学与分子序列分析，明确了10个属的系统位置，为科的划分提供了新的依据；通过运用ITS序列研究睡莲属的种及种下单位之间的亲缘关系，为睡莲类植物的种质资源鉴定提供了新的工具；对水盾草进行了初步的调查分析，为今后深入开展其生态学研究打下了良好的基础。

It mainly covers the original research articles on anatomy, botanical history, chemotaxonomy, morphology, paleobotany, phylogenetic systematics, taxonomy, and phytogeography.

主要收录原始论文，范围涵盖解剖学、植物史、化学分类学、形态学、古植物学、系统发育系统学、分类学和植物地理学。

The journal founded in 1902, publishes original research papers (especially those with regional emphasis on western Europe and tropical Africa), review articles, short communications and book reviews on the systematics of all plant groups and fungi, also covering related fields such as phytogeography, evolution, comparative morphology, pollen and spores, and vegetation studies.

杂志创刊于1902年，刊载原始研究论文（尤其是关于西欧和热带非洲地区的投稿），评论文章，短通讯和书评，内容涉及所有植物群和真菌的系统分类学，同时也包括相关的领域，例如植物地理学，进化，比较形态学，花粉和孢子，以及植被研究。

To understand the degeneration of unfertilized aposporous embryo sac in an aposporous species Pennisetum squamulatum, the central cell in the unfertilized embryo sac was characterized ultrastructurally.

为理解植物无孢子生殖胚囊未受精条件下的退化，对无孢子生殖植物非洲狼尾草未受精成熟胚囊中央细胞退化做了细胞形态学研究。

Blumea was published in 1934, it is an international journal containing papers on descriptive botany (taxonomy, plant-geography, morphology, and anatomy) of Phanerogams as well as Cryptogams.

该刊创刊于1934年，是国际性期刊，刊载论文内容包括显花植物和隐花植物的描述植物学，即植物分类学、植物地理学、形态学和解剖学范畴。

Based on plant morphological traits, some types of strategies could be divided. The regeneration strategies of three species, Eriocaulon buergerianum, Juncus articulatus and Sagittaria potamogetifolia, had characteristics of r-strategists, and Oryza rufipogon, Scirpus triangulatus and Eleocharis plantagineiformis had characteristics of K-strategists.

根据植物的功能形态学特征，可以分出一些生活史对策类型，如从种子特征来看，谷精草、小花灯心草和小慈姑等植物的更新对策具有明显的r-对策特点，粉被苔草、野荸荠和普通野生稻等具有一定的K-对策特点；依据成株特征也可以区分出竞争、躲避或耐压对策的定居对策类型。

The results showed that the total amount of photosynthetic pigments in space flighted seedlings were lower due to significant reduction of chlorophyll a+b content .

因而近年来植物空间诱变的研究十分踊跃，但研究对象多集中于农作物和蔬菜，花卉植物的报道极少，且研究工作多集中在田间观察、形态学等内容[5] 。

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。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.

扫描电镜观察多杀性巴氏杆菌细菌幽灵和菌落形成单位评价遗传灭活率。
