摘    要:采用鱼鳍细胞空气干燥法制片,Giemsa染色,对生活于厦门和海南近海沿岸的2种虾虎鱼染色体核型进行分析研究。其中纹缟虾虎鱼(Tridentiger trigonocephalus)2n=44,有2对中部着丝点染色体(M),13对亚中部着丝点染色体(SM),2对亚端部着丝点染色体(ST)和5对端部着丝点染色体(T),NF=78;拟丝虾虎鱼(Cryptocentroides insignis)2n=50,有9对中部着丝点染色体(M),13对亚中部着丝点染色体(SM),2对亚端部着丝点染色体(ST)和1对端部着丝点染色体(T),NF=98。未发现随体、性染色体和异形染色体。

关 键 词:纹缟虾虎鱼  拟丝虾虎鱼  染色体  核型

Abstract:The author examined the karyotypes of two Gobioid species from Xiamen and Hainan coastal waters by treating fin cells with colchicine-hypotonic air drying and Giemsa staining methods.The results show that Tridentiger trigonocephalus has a diploid number of 44 chromosomes,among which 2 pairs are metacentric chromosomes (M),13 pairs submetacentric chromosomes (SM),2 pairs acrocentric chromosomes (ST) and 5 pairs telocentric chromosomes (T) with a fundamental arm number (NF) amounting to 78.The diploid number of Cryptocentroides insignis is 50,among which 9 pairs are metacentric chromosomes (M),13 pairs submetacentric chromosomes (SM),2 pairs acrocentric chromosomes (ST) and 1 pair telocentric chromosome (T),and its NF is 98.Moreover,no satellite chromosome,sexual chromosome or the special chromosome are detected either in T.trigonocephalus or in C.insignis.
Keywords:Tridentiger trigonocephalus  Cryptocentroides insignis  chromosome  karyotype
