摘要: 60Co-r射线辐射番茄种子,观察辐射种子发芽率、根尖细胞有丝分裂、减数分裂及过氧化物酶同工酶的影响。实验结果表明:辐射剂量10~20krad范围内,种子发芽率最高,有丝分裂畸变率最高,畸变类型最丰富,对减数分裂的抑制小,过氧化物酶同工酶活性最高。

Abstract: The effect on the germination rate, the division of root tip's cells, the meiosis and peroxidase isoenzyme of tomato seeds irradiated with 60Co-Ray and cultivated were observed.The results revealed that the seeds germination rate is highest, the abnormal rate is highest, the type of abnormal chromosome is most abundant, the meiosis is lowest, the activity of peroxidase isoenzyme is highest, when irradiation dose is in range 10-20 Krad.
