When EMS was applied, it was found that 2.0% EMS resulted the highest microkernel rate (15.6‰). Treating the materials with 2.0% EMS for 4 hours could lead to semi-lethal. Cytological observations found that chromosome aberration phenomena such as single microkernel, double microkernel, three microkernel, chromosome bridge, resort chromosome and syncytium were presented in the mutants.

结果 "三步抗体法"在脑切片检测Y染色体阳性信号的灵敏度和特异度分别为85.67％和100％；直接TSA法在脑切片检测Y染色体阳性信号的灵敏度和特异度分别为92.82％和100％。

The relationship of six species from Alaudidae (Alauda arvensis Melanocorypha mongolica Calandrella cinerea Calandrella cheleensis Eremophila alpestris Galerida cristata) distributed in Inner Mongolia were studied from three aspects: Mostly in feather keratins, chromosomal karyotype and morphology adding.The contour feather vance, down feather and shaft of six Larks were studied by means of SDS-PAGE of feather keratins.

本文在羽毛角蛋白、染色体核型及形态学三个层次上，以羽毛角蛋白凝胶电泳分析为主，以染色体核型分析和形态学分析为参考，对分布于内蒙古地区的百灵科Alaudidae的6种百灵鸟的亲缘关系进行研究，包括云雀Alauda arvensis、蒙古百灵Melanocorypha mongolica、短趾百灵Calandrella cinerea、亚洲短趾百灵Calandrella cheleensis、角百灵Eremophila alpestris、凤头百灵Galerida cristata。

Lines which were 2n=21"+1" and one line which was 2n=20"+2", one line which was 2n=43. The salt-resistance addition line Line15 was confirmed as a Disomic alien addition line by C-banding, SSR, FISH methods, and the two alien addition chromosomes had close correlation with the long arm of the second homoeologous group, the centromere region of the third homoeologous group and the short arm of the seventh homoeologous group. We also confirmed the particular C-banding type of the alien addition chromosomes by C-banding following FISH method. The drought-resistance addition line Line17 was found also as a Disomic alien addition line by SSR and FISH detection. The alien addition chromosomes had close correlation with the short arm of the second homoeologous group.

对导入赖草优质耐盐基因的株系Line15进行了C-分带、荧光原位杂交、SSR相结合的鉴定，确认Line15是一个二体异附加系，附加的一对染色体与小麦的第二同源群长臂、第三同源群着丝粒和第七同源群短臂密切相关，并确定了Line15的外源染色体C-分带特征带型，为目后鉴定Line15附加系的真伪提供了简便快捷的途径；对抗旱附加系Line17进行了荧光原位杂交和SSR检测，得出Line17也是一个二体异附加系，外源染色体与小麦的第四同源群短臂密切相关。

In order to obtain viable tetraploids, which remains a major challenge worldwide, research on spindle organization and chromosome behavior was carried out mainly in zhikong scallop, Chlamys farreri, a typical commercially important species which is being cultured in North China Sea. Immunofluorescent technique and laser scanning confocal microscopy has been developed for observation of both microtubule organization and chromosome segregation. Orcein squash method was also used for chromosome observation. A series of complicated configurations of the meiotic spindle and associated patterns of chromosome segregation, including tripolar and seperated bipolar segregation, were found in developing eggs following the inhibition of the first polar body.

为了攻克可存活四倍体人工培育技术的国际性研究难题，本研究选取了我国北方海区的典型经济贝类栉孔扇贝为主要研究对象，建立了一套免疫荧光染色和激光扫描共聚焦显微技术，结合使用染色体地衣红压片观察技术，对第一极体受抑制的受精卵的减数分裂纺锤体装配、染色体分离动态进行了研究，发现了一系列特殊的纺锤体装配及相应的染色体分离行为，包括三极分离、独立二极分离等分离类型，从亚细胞水平上阐明了四倍体形成的细胞学机理。
