2、析。多重比較和單因子方差結(jié)果顯示,3個(gè)群體在2~5個(gè)形態(tài)特征上均存在顯著差異(P一0.05)。采用逐步判別法對(duì)形態(tài)特征綜合分析,利用貢獻(xiàn)率大的參數(shù)對(duì)3個(gè)地理群體進(jìn)行判別分析表明,判別準(zhǔn)確率P1為83.3~100.0,綜合判別率為92.31。以上分析結(jié)果表明,3個(gè)群體間存在一定程度的分化,中、日群體間有明顯的差異,研究結(jié)果可為鈍吻黃蓋鰈群體遺傳學(xué)研究提供形態(tài)學(xué)依據(jù)。關(guān)鍵詞鈍吻黃蓋鰈群體主成分分析多變量解析單因子方差分析判別分析中圖分類號(hào)Q954-3文獻(xiàn)識(shí)別碼A文章編號(hào)1000—7075(2010)05一O015一O7C
