本研究选用16份有代表性的圆果黄麻品种,通过单纤细胞三维结构的显微观测和纤维品质的常规测定,估算了黄麻纤维支数、纤维强力两个品质性状与单纤细胞三维结构因子之间的相关和偏相关。三级偏相关估算结果揭示:纤维支数(6)与单纤细胞长(1)、单纤细胞宽(3)的偏相关系数分别为r_(16.243)=0.8406和 r=26.354=-0.9721,均达极显著水平;纤维强力(7)与单纤细胞长(1)、单纤腔宽(3)、单纤细胞壁厚(5)偏相关系数分别为 r_(17.234)=0.9446、r_(37.125)=-0.6810、r_(57.234)=-0.6841,也均达极显著标准。因此,在育种高代材料观测中,注意对单纤细胞细长,细胞腔小,细胞壁薄的纤维结构材料的选择,可能有效地改良纤维品质,提高品质改良的育种效率。
In this study, we selected 16 representative varieties of Fructus Junctifolia. Through the microscopic observation of the three-dimensional structure of the monocytic cells and the routine determination of the fiber quality, we estimated the relationship between the number of jute fiber, the fiber quality and the three-dimensional structure of the monocytic cells Correlation and partial correlation between factors. The results of partial correlation estimation revealed that the partial correlation coefficients of fiber count (6) to monofilament length (1) and monofilament width (3) were r 16.243 = 0.8406 and r 26.354 = -0.9721, (17.234) = 0.9446, r_ (37.125, r_ (37)) were significantly correlated with fiber strength (7), monofilament length (3), and monofilament cavity thickness ) = - 0.6810, r_ (57.234) = - 0.6841, also reached the extremely significant standard. Therefore, in the observation of breeding high-generation materials, attention should be paid to the selection of fiber structure materials that are slender, small cell cavities and thin cell walls, which may effectively improve the fiber quality and improve the breeding efficiency with improved quality.
