中文摘要：

在海南的正常温度下,四眼斑水龟（Sacalia quadriocellata）在人工饲养环境中无冬眠现象,也未观察到繁殖行为.为研究冬眠对四眼斑水龟繁殖的影响,于2004年12月～2005年2月对其进行低温胁迫实验.选取29只成体四眼斑水龟分成2组,实验组9♀5♂共14只进行低温处理,在8.46±1.61℃干燥环境中保持32天;对照组10♀5♂共15只在正常条件下饲养.结果表明：低温胁迫后,实验组平均体重减小8.68±2.45%,雌雄差异不显著;雄性个体背甲宽从8.55±0.26cm减小到8.46±0.22cm,差异显著（P＜0.05）;雌性个体背甲长从12.97±0.80cm减小到12.94±0.81cm,差异显著（P＜0.05）;雌雄四眼斑水龟甲壳表面积相对低温胁迫前均减小;对照组龟养殖于常温下,甲壳无显著变化,两组龟体重变化量差异极显著（P＜0.01）.影响失重率主要因素是胁迫时间,环境温度对失重呈显著线性正相关（r=0.811,P＜0.05）;形态特征的变化可能与繁殖机制、代谢有关.

英文摘要：

29 Sacalia quadriocellata were randomly divided into 2 groups for studying the relationship between reproduction and hibernation from December 2004 to Feburary 2005. The test group （9♀5♂） brought in the temperature of 8.46 ± 1.61℃ for 32 days, and control group （10♀5♂ ） under normal environment. The results were found as fallows： After low temperature stress, the weight of the turtles in experiment group decreased by 8.68 ± 2.45% but there were no significance differances between male and female. The width of carapace of male decreased from 8.55 ±0.26cm to 8.46± 0.22 cm （P〈0.05）, and the length of carapace of female decreased from 12.97 ± 0.80 cm to 12.94 ± 0.81 cm （ P〈 0.05 ）. The surface of carapace decreased significantly. Turtles in control group have no significantly changes of carapace but the weight loss revealed significant differances from turtles in expriment group （P 〈 0.01 ）. The weight loss had a positive correlation with the temperature （ r = 0.811, P〈0.05）. The morphological changes might be associated with the reproduction and the metabolism.
