生殖

Ananisogamy The sexual fusion of nonidentical gametes. Anisogamy grades from situations in which the gametes differ only in size to the extreme of oogamy, in which one gamete is a large nonmotile ovum and the other a small motile sperm.

异配生殖：不相同的两个配子的结合叫做异配生殖，通常是一个大而运动能力迟缓的卵和一个小而运动能力强的精子结合。

单性生殖繁殖或由单性生殖所繁殖的植物。

A plant that reproduce s by or is reproduce d by apomixis.

单性生殖繁殖或由单性生殖所繁殖的植物。

A plant that reproduces or is reproduced by apomixis.

Therefore, the use of apomixis also holds great promise as an essential tool for plants sustainable agricultural production and economic crops improvement in the 21 century.

无融合生殖在作物育种上之贡献为能迅速稳定杂种优势并降低杂交种子的生产成本，得以在 21 世纪应用无融合生殖於农业和经济作物改良。

Apomixis provides a unique opportunity to fix and utilize hybrid vigor. A number of research programs around the world have tried to use apomixis as an important plant-breeding tool.

无融合生殖是指不经过雌雄配子融合而产生种子的一种特殊生殖方式，能使基因型的杂合性得以保持，从而可以固定杂种优势，对作物育种具有极其重要的意义。

Apomixis allows the establishment of genetically stable seed propagating clones of crops,which can perpetuate themselves across countless sporophytic generations.

利用植物无融合生殖固定杂种优势，已被认为是一条生产杂交种子的高效途径。近年来，由于RAPD、RFLP和差异显示等技术的应用，已使植物无融合生殖的研究面貌一新。

Apospory The devlopment of the gametophyte directly from the cell of a sporophyte, thus bypassing meiosis and spore production.

无孢子生殖：配子体的发育直接来自孢子体的细胞而不经过减数分裂和孢子产生的生殖过程。

Only one complete corollinae chromosome was detected in Ml4, and was determined corollinae chromosome 9. We have used in situ hybridization of genomic DNA to discrimination the parental chromosomes in Beta Ml 4, suppression of cross-hybridization by blocking DNA was not necessary indicating that the investigated Beta genome contain sufficient species-species DNA enabling the unequivocal determination of genomic composition of the hybrids.In our study , the results of BAC -FISH combined with the analysis of GISH in Beta M14,indicating that present of the corollinae chromosome 9 alone was sufficient to confer apospory in Beta M14 upon celluar and molecular..

BAC克隆16-M11和26-L15携带M14花期特异表达的基因；在M14甜菜对应的有性栽培甜菜染色体上没有出现信号，呈半合子状态；包含的单或低拷贝DNA序列在野生白花甜菜进化过程是共线的；两个BAC克隆部分同源；位于末端重组抑制区，所有这些不同寻常的特性都暗示着：BAC克隆16-M11和26-L15和无融合生殖特性相关，可作为无融合生殖

This species is one of perfect materials to examine the developmental mechanism of plant bract, to explore the developmental relationship between leaf and bract, as well as to study the role and essential function of bract on plant reproductive biology and ecology.

该物种是研究植物苞片发育的分子机理及探讨苞片与叶片发育的相互关系的理想材料，也是探讨苞片在植物生殖生物学及生殖生态学中作用和功能的理想材料。

The absorption and distribution of chromium were studied in ryeusing nutrient culture technique and pot experiment.

采用不同浓度K2CrO4(0，0.4，0.8和1.2 mmol/L)的Hoagland营养液处理黑麦幼苗，测定铬在黑麦体内的亚细胞分布、铬化学形态及不同部位的积累。

By analyzing theory foundation of mathematical morphology in the digital image processing, researching morphology arithmetic of the binary Image, discussing two basic forms for the least structure element: dilation and erosion.

通过分析数学形态学在图像中的理论基础，研究二值图像的形态分析算法，探讨最小结构元素的两种基本形态：膨胀和腐蚀；分析了数学形态学复杂算法的基本原理，把数学形态学的部分并行处理理念引入到家实际应用中。
