摘　　要：研究了凹目白鲑(Coregonusautumnalis)精子在302·6~488.9kPa时的NaCl溶液、D-葡萄糖溶液及D-果糖溶液中的活动情况。结果显示,在NaCl溶液中凹目白鲑精子在395.7kPa具最佳活力,其快速运动时间(fastmovementtime,FT)与寿命时间(lifetime,LT)的最大值分别达43.57s和90.31s;与相同渗透压下NaCl溶液相比,凹目白鲑精子在葡萄糖和果糖溶液中的FT与LT均有不同程度的增加;在葡萄糖溶液中FT与LT的最大值分别为57.67s和97.29s,在果糖溶液中则为70.44s和105.29s。说明凹目白鲑精子活力不但与溶液渗透压有关,而且与溶液溶质有关。The sperm mobility in 302.6- 488.9 kPa solutions of NaCl, D-Glu and D-Fru was evaluated in Coregonus autumnalis.The results showed that the sperm mobility of C. autumnalis was the best in 395.7 kPa NaC1 solution, with its Fast Movement Time（FT） and Life Time（LT） amounting to 43.57 s and 90.31 s separately. We also found that the sperm mobility increased in the solution of D-Glu or D-Fru in the same osmolarity as NaCl solution. The highest FT and LT were 57.67 s and 97.29 s respectively in D-Glu solution, and 70.44 s and 105.29 s in D-Fru solution respectively. We concluded that sperm motility is related not only with the osmolarity, but also with solutions.
