Abstract
|
|
|
The growth of Korean axolotl., Hynobius leechii, was analyzed in natural water as control group and in six copper ion groups contaminated by 0.1, 0.2, 0.3, 0.4, 0.5, 0.6ppm of copper ion.
The copper ion checks the growth of the axolotl. The axolotl was not survived during 30 days in the copper ion of 0.3ppm, and, in the 0.4ppm the axolotl was not survived during 10 days after hatch. The growth of head width and body length show a convexing increase pattern, While that of hind leg shows a concaving increase pattern. The copper ion checks the development of hind leg. In the growth quantity of head width, body length and hind leg, that of natural water show the most rapid increase pattern, and copper ion groups of 0.1, 0.2, 0.3ppm follow in that order. The coefficient of relative growth(α) of control group is the greatest value, and the copper ion groups of 0.1, 0.2, 0.3ppm follow in that order. The contaminated groups show the negative allometry in the relative growth of the contaminated groups to the natural water. Body length shows positive allometry, while hind leg shows negative allometry in the relative growth to head width.
