The age-related dynamics of chromosomal instability and germination capacity of welsh onion (Allium fistulosum L.) seeds have been studied under two different storage temperatures during six years after harvesting. Seeds that were kept at the room temperature (14-28 degrees C) during 6 years of storage have lost their germination capacity. The frequencies of aberrant anaphases grew from 2% on the first month of storage up to 80% on the 75th month of storage. The germination capacity of seeds kept at the lower temperature (4-9 degrees C) was 73-77% on the 6th year of storage and the frequency of aberrant anaphases remained within the limits of 2-4%. Thus, storage of welsh onion seeds during 6 years at the lower temperature allows to retain germination capacity and restrains the augmentation of chromosomal instability in root meristem cells of seedlings during this period.
研究了大葱（Allium fistulosum L.）种子在收获后六年内，在两种不同储存温度下与年龄相关的染色体不稳定性和发芽能力动态。在室温（14-28摄氏度）下储存6年的种子失去了发芽能力。异常后期的频率从储存第一个月的2%增长到储存第75个月的80%。在较低温度（4-9摄氏度）下储存的种子在储存第6年的发芽能力为73-77%，异常后期的频率保持在2-4%的范围内。因此，大葱种子在较低温度下储存6年可以保持发芽能力，并在此期间抑制幼苗根分生组织细胞中染色体不稳定性的增加。
