| 摘 要： | 测定了637尾1龄长尾琉金金鱼体重、体长、体高、头长、尾柄长、尾柄高、胸鳍长、腹鳍长、背鳍高、臀鳍长、尾鳍长等11个性状,计算性状间的相关系数,同时采用通径分析方法计算以形态性状为自变量对尾鳍长作依变量的通径系数、决定系数,对各性状的影响大小进行削分.结果显示,尾柄高对尾鳍长的直接影响最大,胸鳍长和尾柄长对尾鳍长的直接...

| Abstract: | 637 individuals of one-year-old long tail Ryukin were collected for measuring the morphometric attributes,including the body weigh,body length,body height,head length,tail handle length,tail handle height,pectoral fin length,ventral fin length,dorsal fin height,anal fin length and caudal fin length.The correlation coefficients among the attributes were calculated,and then path analysis was conducted by taking the caudal fin length as a dependent variable,and other ten morphometric attributes as independent ... |
