2N gametes are the result of meiotic mutation during micro- and mega-sporogenesis that bear the sporophytic rather than the gametophytic chromosome number. This paper reviewed the genetic markers including the morphologic, cytological, isozymes and DNA markers, which have been employed in the generation, inheritance, heterozygosity and marker-assisted breeding of 2n gametes based on the frequency of large pollen grains, cytological analyses, unexpected occurrence of polyploidy progeny and the associations between parents and progenies.

文章综述了植物2n配子发生及其遗传标记研究现状，论述涉及有关形态学标记、细胞学标记、同工酶标记乃至DNA标记等遗传标记在2n配子研究中的应用，指出通过花粉形态观察、大小孢子母细胞减数分裂行为观察、杂种后代倍性鉴定以及亲子分子标记相关分析等，对2n配子发生、2n配子遗传类型与杂合性以及2n配子在育种实践中的有效性等进行研究。

It was found that the fungus 1403 resembles pathogenic F. verticillioides (teleomophy Gibberella moniliforme) in the production of false head or chains and abundant microconidia on the aerial mycelium, but different in the occasional formation of polyphialides with relatively long as well as short monophialides, in its typical coiled hyphae and mycelia fusion.

基于1403在形态学方面具有以下特征：产小型分生孢子的分生孢子梗较长，小型分生孢子呈椭圆形，大型分生孢子线形或略微弯曲，本文将它与有类似形态特征的镰刀菌进行了比较，发现1403与植物病原菌Fusarium verticillioides（有性态为Gibberella moniliforme）表面上很相似，气生菌丝均可产生大量假头状或链状的小型分生孢子，但深入的研究却发现1403与F。

The journal dedicates to the studies of the taxonomy, phylogeny and evolution of botany. Research areas mainly include plant diversity conservation, molecular phylogenetics, population biology, morphology, biodiversity, herbaria and nomenclature etc.

In the present project,the project group investigated Cololejeunea flora of some provinces of China, collected over 500 specimens of Cololejeunea and over 7000 specimens of other liverworts,and borrowed over 3500 specimens （including 416 types）from other important herbaria. The species diversity and distribution weree clarified preliminary by means of mophologocal and ecologoical observation and studies on oil bodies and chromosomes as well as bioactivity of some species.

本项目对我国部分省区作了详尽的野外考察，采集了500余份我国疣鳞苔属的标本和7000多号其它苔类植物标本，从世界各大标本馆借阅了3500余份标本（包括416份模式标本），通过形态学，解剖学和生态学的观察，结合一些种类的染色体和油体以及生物活性的研究，初步搞清了我国和其它亚洲国家疣鳞苔属的种类和分布。

Based on morphologic and biomass measurement comparisons of morphology and resource allocation of Plantago major and P. depressacollected in the same environment have been made. The results show that quantitative relationships and resources allocations between different modules are proper in different species, they can reflect unprejudicedly ecological characteristics of individuals.

本文通过对取自同一生境条件下的两种车前属植物，即大车前和平车前(P 。depressa)不同构件间的形态学特征和生物量相关关系的比较分析，发现构件间的数量关系和各构件在资源配置上具有种间特异性，各构件生物量间的数量关系及各构件在资源配置上的数量关系，更能真实地反映出物种个体的生态学特征。

The leaf epidermises of the major species of Psathyrostachys , Critesion and Hordelymus in Poaceae were examined, their similarities and differences on the leaf epidermis were summarized, and the taxonomic significance of leaf epidermal features among them also were discussed.
