摘要
为了给莲的多倍体育种提供细胞学依据，以寸三莲及其变异株为材料，采用涂抹制片法研究莲花粉母细胞减数分裂行为，观察结果表明：二倍体莲花粉母细胞减数分裂形成四分体的方式属连续型，四分体两侧对称．经秋水仙素处理后莲的花粉母细胞在减数分裂过程中染色体数目发生改变，减数分裂行为发生异常，如见环状染色体、染色体落后、减数分裂不同步及双核仁等现象．
The meiosis of pollen mother cells in lotus cv. Cunsanlian was cytologically observed by smear. The observations showed that the meiosis in the diploid lotus was successive and the tetavds formed bilaterally symmetric. After treated with colchicine,the lotus changed the number of chromosomes and produced the abnormal meiosis such as chromosomal ring,chromosome laggard,nonsynchronic meiosis and binucleolus.
