| Abstract/Contents: | "The irradiation of 60Coγ ray can induce different types of variation and irradiation breeding has been applied to turfgrass variety improvement as one effective method. The cytological effects of 5 kinds of dosages of 60Coγ ray on Buchloe dactyloides (Nutt) Engelm. Seeds were evaluated and the results show that the γ ray irradiation inhibited the mitoses of root tip cells. And the mitotic index of root tip cells decreased along with the increased dosage. Furthermore,the γ ray irradiation induced the chromosomal and nuclear aberration, such as bridge, chromosome fragment, chromosome conglutination, chromosome dissociation, draggling chromosome, single micronucleus, double micronucleus, multi-micronucleus, and small micronucleus in root tip cells of B. dactyloides. The higher the γ-rays irradiation dosage, the higher the rate of aberration from the irradiation dosage of 0 to 2000 Gy; all the aberration rates reached to the maximum at 2000 Gy." |
