伸直长度

各性状之间存在一定的相关关系，其中产毛量与羊毛纤维伸直长度、自然长度与伸直长度之间存在极显著正相关（P＜0.01）。

There is high correlation between yield of wool and mean fiber length , mean fiber length and natural mean fibre length ( P < 0.01 ) .

羊毛纤维伸直长度分别为（12.29±1.75）cm、（11.61±1.82）cm，且差异极显著（P<0.01）；

Mean fibre length was ( 12.29 ± 1.75 ) cm and ( 11.61 ± 1.82 ) cm respectively , and the difference is significant ( P < 0.01 );

毛纤维伸直长度净增加10.8%；

Extending length of wool fiber increased 1O . 8 % ;

结果表明，绒毛伸直长度、体重、胸围是影响产绒量的主要因素。

The results indicated that the body weight , the stretched down length and the heart girth were the most important factors affecting the yield .

结果表明，1F1绒自然长度和伸直长度分别为9.13,10.69cm，明显比陕北土种山羊绒长；

The results were as follows : ( 1 ) The stretched length ( 10.69 cm ) and natural length ( 9.13 cm ) of F 1 down fiber were much longer than that of North Shaanxi local goat and cashmere goat ;
