低温处理对黄喉拟水龟胚胎发育的影响
Effects of low temperature on embryonic development of yellow pond turtle, Mauremys mutica
摘要
Abstract
Objective] To study the effects of low temperature on embryonic development of yellow pond turtle Mauremys mutica.[Method] Eggs of M.mutica were stored in vermiculite with a water potential of-150 kPa at 14,18,20 ℃for 30, 60 and 90 days respectively , and then were incubated at 29 ℃with the same water potential .The characters correlated to embryonic development were measured .[Result and conclusion]All eggs lost mass after being stored at 14 , 18 ℃, but there was no difference at 20℃. The eggs which were incubated at 29 ℃ increased in mass .There were hatchlings at three temperature treatments.The hatching success rates were very low , with the highest hatching success rate being 33.33%.The incubation period at 29℃of all treatments which hatched out successfully decreased with storage temperature rising and time increasing .Abnormality ratio increased with the storage period exten-ding at low temperatures .The results suggested that embryonic development of yellow pond turtle would be influenced or even die if it was exposed to low temperatures for a long time .关键词
