摘要: 染色体荧光显带技术不仅可以显示出染色体的基本形态特征如大小、主次缢痕、随体等,还可应用于核型分析,在植物进化生物学,人类和动物染色体结构和功能研究等生物学研究中发挥了较大作用。目前我国高校的生物学实验教学中,缺少相关内容的设计和安排。作者选用啤酒花(Humulus lupulus)这一经济作物作为实验材料,将染色体制片和荧光显微镜技术融合在一个实验中,并对该实验做了多次实践,设计了一整套适合生物学实验教学的方案。该实验直观、系统地展示了染色体荧光显带技术,实验结果有意义且具有一定的潜在应用价值,同时也训练了学生的实验技能,拓展了学生的知识领域。还为染色体荧光显带技术在生物学实验课程中的推广提供了有益建议。

Abstract: Chromosome fluorescence banding technology not only can reveal chromosomal basic features including size, primary constriction, secondary constriction, satellite etc., but also contributes to karyotpe analysis. Obviously, it plays a significant role in biological studies, such as plant evolutionary biology, chromosome research in human and animal, and so on. However, there has been no chromosome fluorescence banding related to biological experimental teaching for undergraduates and graduates in colleges at present. Therefore, for students experimental practice, we used Humulus lupulus, an economic crop, as material and designed a complete experimental teaching program, containing chromosome preparation and fluorescence microscopy technology. The experiment shows the chromosome fluorescence banding technology visually and systematically, and the result is meaningful with potential application value. Meanwhile, student can learn lots of experiment skills and develop their knowledge during this experimental practice. Besides, this experimental teaching program provides some beneficial suggestions for popularizing chromosome fluorescence banding technology in biological teaching course.

Key words: Humulus lupulus, sex chromosome, fluorescence banding, experimental course
