| 6. | The larvae emerge from the leaves in mid - to late - may of next year and feed on fresh leaves of palms 卵和幼虫由于裸露在棕叶背面,易被天敌吃掉,存活率低。卵孵化率为50 % ,幼虫存活率为49 . 1 % 。 |
| 7. | It is shown from the comparisons between hatch times , hatch rates , abnormal rates and activities in different conditions that temperature has significant effects on the hatch of fertilized eggs 通过对孵化时间、孵化率、初孵仔鱼畸形率、活力的比较,发现温度对受精卵的孵化影响显著。 |
| 8. | " i hlrough the comparisorl of the breedi11g process , their clt1tch size was differcnt significamly , hl ) wevef , the number of the nestlings ; 1nd survivals , the incubation rate and survival rate were not different significantly between two species 通过对白鹭和池鹭的繁殖过程比较,两种鹭的窝卵数存在显著差异,具有种的特异性。但两种鹭的窝雏数、出雏数、孵化率和成活率均差异不显著。 |
| 9. | With the cold shock , the diploid eggs also developed to diploid gynogens after the activation of the uv - irradiated sperm , no tetraploid gynogens being found , suggesting that it is difficult to double the chromosome from the diploid to tetraploid by means of cold shock treatment 没有检测到雌核发育四倍体。这表明通过冷休克让二倍体卵子加倍成四倍体比较困难,但是经冷休克处理获得的雌核发育鱼的孵化率高于没有进行冷休克处理的。 |
| 10. | The eggs were put in an incubator filled with sand collected from their birthplace and kept at 28 to 30 degrees celsius . after two months of incubation , 85 of the 121 eggs collected hatched out baby turtles , giving a hatching rate of over 70 per cent . " the new - born turtles were about 23 grams in weight and five centimetres in carapace length 渔护署护理员将该窝为数一百二十一只的海龟蛋放置在数个篮内,铺上从深湾取来的沙,再放进人工孵化箱中,孵化箱的温度须保持在摄氏二十八度至三十度,两个月后,成功孵出八十五只小海龟,孵化率超过七成。 |
