摘　　要：鸡蛋品质变化原因众多,其中一个主要影响因素是其自身的呼吸作用,而蛋壳超微结构又与呼吸作用息息相关。为了揭示蛋壳各层超微结构与鸡蛋呼吸强度之间的关系,通过扫描电子显微镜获得蛋壳的超微结构图像,利用MATLAB软件获取相关参数,并用SPSS 19.0软件得出蛋壳厚度、有效层厚度、乳突层厚度、平均乳突大小以及孔隙度与鸡蛋呼吸强度的相关关系。结果表明:鸡蛋的呼吸强度与蛋壳厚度(R=-0.36,P<0.05)、有效层厚度(R=-0.47,P<0.05)之间存在显著性负相关关系;鸡蛋的呼吸强度与平均乳突大小(R=0.57,P<0.01)、孔隙度(R=0.66,P<0.01)之间存在极显著性正相关关系;与乳突层厚度的相关性较低,同时得出呼吸强度大的鸡蛋蛋壳表面比呼吸强度小的蛋壳表面粗糙。总之,蛋壳厚度、有效层厚度、平均乳突大小以及孔隙度对鸡蛋呼吸强度影响较大。There are many reasons for the quality changes of egg.One of the major factors is its respiration,which is closely related to eggshell ultrastructure.In order to determine the relationship between the ultrastructure of eggshell layers and respiratory intensity of eggs,scanning electron microscopic(SEM)images of the eggshell were obtained,and the relevant parameters were obtained by MATLAB software.The relationship between eggshell thickness,effective layer thickness,mammillary layer thickness,the average size of mammillary cones and porosity and respiratory intensity of eggs was studied by SPSS 19.0 software.The experimental results showed that respiration intensity of eggs was significantly negatively correlated with eggshell thickness(R=-0.36,P<0.05)and effective layer thickness(R=-0.47,P<0.05)but was significantly positively correlated with the average size of mammillary cones(R=0.57,P<0.01)and porosity(R=0.66,P<0.01).In addition,there was a low correlation between mammillary layer thickness and respiratory intensity.The higher respiration intensity of eggs,the more rough the surface of eggshell.Therefore,eggshell thickness,effective layer thickness,the average size of mammillary cones and porosity can pronouncedly affect respiratory intensity of eggs.
