摘要： 为探索西北地区在芝麻生殖生长阶段干旱胁迫条件对资源的影响，为我国抗旱品种改良提供亲本，本试验选择山西省农业科学院经济作物研究所为试验点，用中国农业科学院油料作物研究所提供的14 个抗旱资源为试验材料，在芝麻生殖生长阶段进行干旱胁迫处理，调查生育期、出苗率、存活率、株高、叶片数、生物产量、经济产量，进行对比分析。结果显示：干旱胁迫条件下，晋芝1 号、晋芝2 号生殖生长期长，为59 天；幼苗存活率高，为96.6%~100%；株型高大，分别为179.1cm、149.16cm；叶片多，分别为78.3 个、74.8 个；生物产量高，鲜重分别为8.23g、7.61g；干重分别为7.54g、6.82g；经济产量高，晋芝2 号127.50g，晋芝1 号80.0g。表明干旱胁迫不利于芝麻的生长，参试材料中晋芝1 号、晋芝2 号抗旱能力强，可以作为抗旱品种改良的亲本材料和遗传研究的核心材料。

Abstract: In order to explore the effects of drought stress on growth of sesame in Northwest region and provide parents of drought-resistant varieties, the study selected the Institute of Industrial Crops, Shanxi Academy of Agricultural Sciences as a test point and 14 drought varieties provided by Oil Crops Research Institute, Chinese Academy of Agricultural Sciences as test materials, to conduct a drought stress treatment in the growth stage of sesame. The author analyzed growth period, emergence rate, survival rate, height, number of leaves, biological yield and economic yield. The results showed that under drought stress conditions, Jin Zhi 1 and Jin Zhi 2 had a long reproductive cycle about fifty-nine days, high seedling survival rate about 96.6%-100% and high height of 179.1 cm and 149.16 cm, respectively. Jin Zhi 1 and Jin Zhi 2 had more leaves which were 78.3 and 74.8, respectively, high biomass yield with fresh weight of 8.23 g and 7.61 g and dry weight of 7.54g and 6.82g, and high economic output which were 80.0g and 127.50 g. Drought stress is not conducive to the growth of sesame, Jin Zhi 1 and Jin Zhi 2 had strong drought resistance among the tested materials, and could be used as improved varieties of drought parent materials and a core material of genetic research.
