摘　　要：试验对核桃坚果硬壳结构(缝合线紧密度、厚度、机械强度)与坚果硬壳中的木质素、纤维素含量进行了比较,并分析了三者之间的相关性。结果表明,核桃硬壳结构指标之间存在显著的相关性,不同核桃品种(系)之间硬壳中木质素、纤维素含量存在着显著差异。硬壳木质素含量在31.09%～51.88%,纤维素含量在10.97%～16.00%,硬壳木质素含量与缝合线紧密度、机械强度之间呈显著的正相关关系,与硬壳厚度呈极显著的正相关关系。The shell structure(suture line density,thickness,mechanical strength) of walnut(Juglans regia L.) and the content of lignin,cellulose content in nut shell were compared;and the correlation among them was analyzed.The results revealed significant correlation among the shell structure indexes.The lignin and cellulose content of different walnut varieties(lines) differed significantly.The content of lignin and cellulose in nut shell was 31.09% ～51.88% and 10.97% ～16.00%,respectively.The correlation between lignin content and suture line density or mechanical strength was significantly positive;while between lignin content and shell thickness was extremely significantly positive.
