摘要/Abstract

摘要： 在4个温度(15 ℃、20 ℃、25 ℃和30 ℃)下对4个不同生化遗传特征的萼花臂尾轮虫克隆(A、B、C和D)所产幼体的耐饥饿时间及其与温度、轮虫个体大小和卵大小等的关系进行研究.结果表明，15 ℃下克隆B幼体耐饥饿时间最短，为45.67 h；20 ℃和25 ℃下克隆C幼体耐饥饿时间均最长，分别为61.33 h和72.01 h；30 ℃下克隆A幼体耐饥饿时间最长，为40.11 h.4个温度间，克隆A轮虫幼体的耐饥饿时间在15 ℃下最长，克隆B和C轮虫幼体的耐饥饿时间在30 ℃下均最短，克隆D轮虫幼体的耐饥饿时间随培养温度的升高而逐步显著缩短.4个克隆轮虫的幼体耐饥饿时间均与温度呈显著负相关关系.克隆A轮虫的幼体耐饥饿时间还与卵体积呈显著负相关，克隆C相反；克隆B和克隆D轮虫幼体耐饥饿时间与个体体积呈显著正相关关系.

Abstract: This paper studied the neonate starvation-endurance duration of four Brachionus calyciflorus clones (Clone A, B, C and D) with different biochemical-genetic characteristics at 15 ℃, 20 ℃, 25 ℃ and 30 ℃, and the relationships of this duration with the temperature and the body- and egg volumes of B. calyciflorus. The results showed that at 15 ℃, the neonates of Clone B had the shortest starvation-endurance duration (45.67 h); at 20 ℃ and 25 ℃,the neonates’starvation-endurance duration of Clone C was the longest, being 61.33 h and 72.01 h, respectively; while at 30 ℃, this duration of Clone A was the longest (40.11 h). The neonates’ starvation-endurance duration of Clone A was the longest at 15 ℃, those of Clone B and C were the shortest at 30 ℃, while that of Clone D decreased with raising temperature. The neonates’ starvation-endurance duration of all the four clones was negatively correlated with temperature. There was a negative correlation between this duration of Clone A and its egg volume, and the reverse was true for Clone C. The neonates’ starvation-endurance duration of Clone B and D was positively correlated with the body volume of rotifer mother.
