摘要
为了能够直接通过外部形态特征判断中国林蛙的产油量,本文采用单因素回归和逐步回归分析方法,初步研究了黑龙江省中部地区中国林蛙(RanachensinensisDavid)雌体的体重、体长、前后肢长、卵重、年龄与产油量(左右输卵管重量之和)之间的关系。结果表明:产油量与体重、体长、前肢长、后肢长、卵重、年龄均存在正相关;产油量与体重和体长具有显著的正相关(r=0.930),其回归方程:y=-0.566+0.016x+0.072x。因此,体重和体长可以作为判断产油量多少的重要指标。
In order to directly predict the oviduct weight of Rana chensinensis by morphological character,the relationships among body weight,body length,forelimb length,posterior limb length,egg weight,age and oviduct weight of female Rana chensinensis were investigated by the method of one-way analysis and stepwise regression in the middle regions of Heilongjiang Province from April to May,2004.The results showed that oviduct weight(total weights of the left and right oviducts)was positively related to body weight,body length,forelimb length,posterior limb length,egg weight,and age; and oviduct weight had significantly positive relation to body weight and body length(r=0.930),and the regression equation:y=-0.566+0.016x 1+0.072x 2 was modeled(x 1=body weight,and x 2=body length).Therefore,body weight and body length as the important indexes measured can predict the oviduct weight.
