摘　　要： 通过对两种发育方向的西葫芦幼瓜瓜重与纵横径进行偏相关分析,得到幼瓜正常发育初期瓜重与纵横径的线性模型是: G= - 904 .52 + 71 .25L1 + 56 .2L2 , 方程显著存在,且偏回归系数为0 .0010 ,达到极显著。但是由于在幼瓜最终发育中断时,得到只包含横径的线性方程G= 0 .72 + 19 .32L2 ,偏回归系数0 .0096 ,也达到极显著。以上模型方程说明,如果发生化瓜,瓜重与纵横径之间的关系则进一步变小,以至于与纵径无关。在化瓜条件下幼瓜的纵径比横径更为敏感。 The correlation between weight and length or width of pumpkin's young fruits developing in two directions were studied.Using deviation correlation analysis,a lineal equation of the correlation during young fruits'normal development were gotten:G=-904.52+71.25L\-1+56.2L\-2.The equation existed markedly.Its extremely marked coefficient of deviation regression is 0.0010.However,when finally stopped to develop,the above equation changed to G=0.72+19.32L\-2.The equation also existed markedly.Their extremely marked coefficients amount to 0.0096.It is inferred that if fruits finally die,the correlation between weight and length or width gradually gets smaller.As a result the length becomes unrelated with the weight.The length is more sensitive than width under the conditions of fruits'death.\;
