摘要： 为了研究产地及籽粒外观对芝麻木酚素含量的影响,为芝麻品质遗传改良及高木酚素芝麻商品生产提供理论依据。从3 800余份芝麻种质资源中选取212份代表性资源,分别在4个不同生态区种植,测定各样品芝麻素和芝麻林素含量;探讨芝麻不同产地、千粒质量及种皮颜色与芝麻素和芝麻林素含量的关系。结果表明,芝麻素和芝麻林素各试点含量均值分别为3.52,3.61,3.11,2.43,1.94,1.93,1.78,1.62 mg/g;芝麻木酚素含量存在随纬度升高而增加的趋势;芝麻籽粒颜色L值与芝麻素含量极显著正相关(r=0.296 6, ɑ =0.01),与芝麻林素含量相关不显著;千粒质量与芝麻素含量极显著负相关(r=-0.260 3, ɑ =0.01),与芝麻林素含量极显著正相关(r=0.227 9, ɑ =0.01)。芝麻素和芝麻林素含量随产地纬度的升高而增加;随着种皮颜色变深,芝麻素含量逐渐降低;随着千粒质量增加,芝麻素含量逐渐降低,芝麻林素含量不断增加。

Abstract: The purpose of this study was to investigate the effects of producing area and appearance quality on lignan contents of sesame seeds to provide a theoretical basis for genetic improvement of sesame seed quality and producing sesame production with high lignan content.Two hundred and twelve typical sesame cultivars/lines, chosen from more than 3 800 accessions of sesame germplasm resources, were simultaneously grown in 4 different ecological zones.And the sesamin, sesamolin content, kilo-seed weight and seed-coat color of the 212 seed samples yielded in each area were measured.And the relationships between sesamin and sesamolin content with producing area, kilo-seed weight and seed coat color were analyzed.The average contents of sesamin and sesamolin of four producing areas were 3.52, 3.61, 3.11, 2.43, 1.94, 1.93, 1.78, 1.62 mg/g, respectively.There exists the tendency of increasing lignan contents of sesame seeds with the rising of yielding area latitudes.Furthermore, an extremely significantly positive correlation was found between seed-coat color L value and sesamin contents(r=0.296 6, ɑ =0.01)and no significant correlation was found between seed-coat color L value and sesamolin;an extremely significantly negative correlation was found between kilo-seed weight and sesamin contents(r=-0.260 3, ɑ =0.01) and a significantly positive correlation was found between kilo-seed weight and sesamolin contents(r=0.227 9, ɑ =0.01).The sesamin and sesamolin contents rose gradually with the increase of yielding area latitudes.With the darkening of the seed-coat color from white to black, sesamin content was gradually increased.With the increasing of kilo-seed weight, the sesamin content was gradually decreased, and the sesamolin content gradually increased.
