摘　　要：为补充亚成体林麝(Moschus berezovskii)泌香量、麝香质量性状数据,分析年龄与麝泌香量时空效应。采集88只林麝(1.7~14.7岁)各年龄组泌香量数据,随机对亚成体年龄群中10只麝麝香分泌量及色泽、形状进行观察和记录。结果显示,亚成体麝泌香量呈常态分布(W=0.855,P=0.066>0.05),取值范围为6.20 g~16.50 g,平均泌香量(9.40±3.311)g/只,变异系数达35.223%,低产香麝占70%、中产麝占20%、高产麝占10%;深棕色麝香占30%、棕色占50%、浅棕色和褐色均占10%,干粉状占30%、粉状占60%、干泥状占10%,泌香量与色泽、形状间均无明显关联(P>0.05);构建年龄与泌香量的曲线模型拟合度较高(R^(2)=0.8358)、年龄与泌香量间呈显著负相关(r=0.646,P=0.017<0.05)。综上所述,观测群亚成体林麝泌香量相对偏低、离散度和选育潜力较大,麝香多呈棕色与粉状、质量较优,泌香量与色泽、形状无关联;麝群泌香量随年龄呈快速提升,至峰值、高峰期震荡式小幅下降、7.7岁后显著下降,至8.7岁后小幅提升又再次快速下降的趋势特征。To supplement the musk yield and quality traits of sub-adult forest musk deer(Moschus berezovskii),we analyzed the spatio-temporal response relationship between age and musk yield.The average musk yield of 88 forest musk deer at different ages(1.7~14.7 years old)was collected individually;the yield,color and shape of musk from 10 forest musk deer in the sub-adult age group were observed and recorded.The results showed that musk yield of sub-adult musk deer was normally distributed(W=0.855,P=0.066>0.05),with a rang from 6.20 g to 16.50 g,and the average musk yield was(9.40±3.311)g,which varied greatly(CV=35.223%);low musk yield individuals was 70%,medium yield individuals was 20%,high yield individuals was 10%.Dark brown musk was 30%,brown musk was 50%,light brown and tan musk were respectively 10%,dry powder was 30%,powdery musk was 60%,dry mud musk was 10%,there were no significant difference between musk yield and color,shape(P>0.05).Acurve regression model curve regression model with high fitting degree(R^(2)=0.8358)was established,there was a significant negative correlation(r=0.646,P=0.017<0.05).In summary,the musk yield of subadult forest musk deer was relatively lower,high dispersion and breeding potential,and themusk wasmostly brown and powdery with better quality,the musk yield had no correlation with color and shape.The musk yield showed a trend of rapid increase to peak with age,a small oscillatory decrease during the peak period,a significant decrease after 7.7 years old,and a small increase and then a rapid decrease again after 8.7 years old.
