| 用60 Co C射线辐照文蛤幼贝, 研究其对文蛤生长及抗病性的影响。A 组预试验结果表明: 低剂量60 Co C射线辐照对促生长有效, 高剂量辐射抑制了文蛤生长。B组正式试验辐照剂量(低剂量) 3. 23 @ 10- 7 ~ 25. 80 @ 10- 7C / kg。低剂量辐射试验结果表明: 46 d后, 试验组平均壳高及平均体重均高于对照组, 分别增加15% ~ 21% 和16% ~ 26%; 276 d后, 试验组的平均壳高较对照组增加17% ~ 23%, 且试验组文蛤的抗病性远优于对照组。61 45@ 10- 7 ~ 19. 35 @ 10- 7 C /kg 低剂量为促进文蛤幼贝生长、提高抗病性的有效剂量范围。

| 英文摘要: |
| Juveniles of Meretrix meretrix Linnaeus were treated with ^60Co γ-rays radiation in order to study effects on their growth and resistance. The research was designed into two parts named A and B, both of which were composed of one blank group and five test groups . After cultured in the sea for 46 days, A showed that low - dose ^60Coγ -ray radiation was good for promoting growth, while high -dose radiation of 95.46 × 10^-7 C/kg to 2363 × 10^-7 C/kg restrained the juveniles＇growth . Therefore, suitable doses ranged from 0 ×10^-7 C/kg to 25.80 × 10^-7 C/kg were selected to design B, and the juveniles were cultured for 46 and 276 days respectively. B showed average height and average weight of five test groups irradiated by ^60Co γ- ray were higher than blank group after 46 days cultured, and the two indexes were increased by 15% -21% and 16% -26% respectively. Continued to be cultured for 276 days in the sea, test groups were increased by 17% -23% , and irradiated test groups＇resistance excelled the blank group which was not irradiated. The juveniles were irradiated by ^60Co γ-ray ranged from 6.45×10^-7 C/kg to 19.35 × 10^-7 C/kg, which effect the growth and resistance greatly. Consequently, the suitable dosage of irradiation to juveniles was 6.45 × 10^-7 C/kg - 19.35 × 10^-7 C/kg. |
