%X 目的：通过对不同贮藏时间的梭梭和四翅滨藜的种子质量研究，为肉苁蓉种植产业规模化、规范化生产提供优质的寄主种子种苗来源。方法：以贮藏1年和2年的梭梭、四翅滨藜的种子为材料，测定种子净度、千粒重、含水量、吸水规律等指标并进行分析。结果：结果表明，贮藏1年的梭梭和四翅滨藜的种子千粒重、含水量均高于贮藏2年的，但种子净度和种子形态大小不受贮藏时间的影响；贮藏1年的梭梭种子吸水量和吸水速率低于贮藏2年，四翅滨藜则相反；不同的萌发温度处理下(10℃、15℃、20℃、25℃、30℃)，梭梭种子在15℃时发芽速率最快，且贮藏1年的发芽速率大于贮藏2年的；四翅滨藜种子在25℃沙培条件下，贮藏2年的种子发芽率、发芽势、发芽指数均高于贮藏1年的，发芽表现较好。结论：贮藏1年的梭梭种子质量较优，发芽适宜温度为15℃；贮藏2年的四翅滨藜种子质量优于贮藏1年的，四翅滨藜种子存在后熟现象，贮藏后的种子质量较佳。<br />
Objective: To provide a high-quality source of host seedlings for the large-scale and standardised production of <i>Cistanche</i><i> </i><i>deserticola</i> plantation industry by studying the seed quality of two host plants (<i>Haloxylon</i><i> </i><i>a</i><i>mmodendron</i> and <i>Atriplex</i><i> </i><i>canescens</i>) with different storage times. Methods: Seeds of <i>Haloxylon</i><i> </i><i>ammodendron</i> and <i>Atriplex</i><i> </i><i>canescens</i> stored for 1 and 2 years were used as materials, and the indexes of seed clarity, thousand-seed weight, water content, and water absorption pattern were determined and analyzed. Results: The results showed that the thousand-seed weight and water content of the seeds of <i>Haloxylon</i><i> </i><i>ammodendron</i> and <i>Atriplex</i><i> </i><i>canescens</i><i> </i>stored for 1 year were higher than that of those stored for 2 years, but the seed clarity and seed morphology and size were not affected by the storage time; the water absorption and rate of water uptake of the seeds of <i>Haloxylon</i><i> </i><i>ammodendron</i> stored for 1 year were lower than that of those stored for 2 years, while the opposite was true for <i>Atriplex</i><i> </i><i>canescens</i>; under the treatment of different germination temperatures (10？C, 15？C, 20？C, 25？C, 30？C), the fastest germination rate of the <i>Haloxylon</i><i> </i><i>amm</i><i>o</i><i>dendron</i> seeds was at 15？C, and the germination rate of 1 year storage was greater than that of 2 years storage; <i>Atriplex</i><i> </i><i>canescens</i> seeds were stored for 2 years at 25？C under the condition of sand cultivation, and the germination rate, germination potential and germination index of 2 years’ storage were higher than that of 1 year’s storage, and the germination performance was better. Conclusion: The quality of <i>Haloxylon</i><i> </i><i>ammodendron</i> seeds stored for 1 year was better, and the suitable temperature for germination was 15？C; the quality of <i>Atriplex</i><i> </i><i>canescens</i> seeds stored for 2 years was better than that of those stored for 1 year, and there was the phenomenon of after-ripening of <i>Atriplex</i><i> </i><i>canescens</i> seeds, and
