在实验室条件下，对三个野生种群、人工养殖种群和杂交种群的仿刺参（Apostichopus）活体、水煮和干燥标本的乳突特征进行了研究。肉眼观察发现，不同种群的乳突形态存在明显差异。首次建立了活、煮、干三种状态下的乳突数（PL/L ≥ 0.05，PL为乳突长度，L为体长）的标准判别法。- 是的根据这一标准，对野生、人工养殖和杂交种的活标本、煮标本和干标本的乳突数进行了估计。- 是的结果表明，背、腹乳头的数目在各组间有显著差异。乳头总数以俄罗斯人最多（66.25 ± 8.11），显著大于其他各组（P<0.01）。其次是日本人群和两个杂种组（JJ组53.64 ± 7.88，CR组54.65 ± 4.74，CK组46.29 ± 6.91）。俄罗斯、日本和中国黑×俄黑杂种群体的背、腹乳头数差异显著大于其他群体。这项研究增加了我们对不同种群的A.在选育和水产养殖中具有直接的应用潜力。关键词：仿刺参，乳突，判据，杂种。
We investigated the characteristics of papillae of living, boiled and dried specimens of three wild populations, cultivated and hybrid Apostichopus japonicus in the laboratory. Visual observation showed that the appearance of the papillae was obviously different among the populations. For the first time, we established a standard criterion for estimating papilla number (PL/L ≥ 0.05, PL: the length of the papilla, L: body length) in living, boiled and dried A. japonicus . According to the criterion, we estimated the papilla number in living, boiled and dried specimens of wild, cultured and hybrid A. japonicus . Results show that the number of both dorsal and ventral papillae was significantly different among the groups. The largest total number of papillae was found in the Russian population (66.25 ± 8.11), which was significantly larger than those in the other groups (P<0.01). It was followed by those in the Japanese population and two hybrid groups (53.64 ± 7.88 for JJ, 54.65 ± 4.74 for CR and 46.29 ± 6.91 for CK). The differences between the number of dorsal and ventral papilla in Russian, Japanese and Chinese♂×Russian♀ hybrid populations were significantly larger than those in the other groups. This study increases our understanding of papilla traits in different populations of A. japonicus and has a direct application potential for selective breeding and its aquaculture. Key words: Apostichopus japonicus, papilla, criterion, hybrid.
