【摘要】 在室内工厂化养殖条件下 ,于 1 997年 1 0月对正常盘鲍二倍体个体及用细胞松驰素 B诱导法获得的盘鲍三倍体群的生长情况进行了比较。结果表明 :(1 )在育苗期的 1 4月龄内 ,盘鲍的三倍体群与二倍体个体间在生长上无明显差异 ;(2 ) 1 4月龄后盘鲍的三倍体群与二倍体个体间在生长上出现分化。两周龄的盘鲍三倍体群在壳长和体重上分别比二倍体个体大 1 4.76 %和5 0 .1 9%;两周龄半的盘鲍三倍体群在壳长和体重上分别比二倍体个体大 2 0 .0 0 %和 41 .89%;(3 )如按 6 cm壳长作为商品盘鲍的标准 ,则盘鲍三倍体群只需养殖 2 6个月 (包括育苗期 )即可达到商品盘鲍的标准 ,而二倍体个体则需养殖 3 0个月 (包括育苗期 )。由此可见 ,三倍体商品盘鲍比二倍体商品盘鲍在养殖时间上可缩短 4个月 ;(4)盘鲍三倍体群与二倍体个体群的氨基酸组分相同 ,但盘鲍三倍体群的氨基酸总量比二倍体个体的氨基酸总量高。更多还原

【Abstract】 The triploid population obtained by Cytochalasin B induction in 1997-October and the diploid of Haliotis discus Reeve were raised indoor.We compare their growths and the results are as follows:(1)There is no obvious difference between the triploidy and the diploidy of young abalone in the increase of shell length and total weight in the first 14 months age.(2)There is significant difference between the triploidy and the diploidy of abalone in the increase of shell length and total weight in the 14 months age later:The increase of shell length and total weight of triploidy abalone are faster than that of the diploidy abalone.Our attention has been called to the fact that the shell length of the triploidy abalone raised for two years is 14.76% longer than the diploidy abalone,and its total weight is 50.19% heavier than the diploidy abalone in the correspounding time.The shell length of the triploidy abalone raised for 30 months age is 20.00% longer than the diploidy abalone and its total weight is 41.02% heavier than the diploidy abalone respectively.(3)Up to commodity standard for 6 cm shell length,the triploidy abalone has only been raised for 26 months age but diploidy abalone must have been raised for 30 months age.(4)There is no difference between the triploidy and the diploidy of young abalone in amino acid composing, but the gross content of amino acid in the triploidy is higher than that in the diploidy.更多还原
