目的 针对黄芪种子萌发率低的问题,为筛选促进黄芪种子萌发效果最佳的外源物质及处理浓度.方法 利用赤霉素、水杨酸、硝普钠、6-BA 4种外源物质对黄芪种子进行处理,对黄芪种子发芽率、发芽势、发芽指数、活力指数、根长和芽长等指标进行分析,采用隶属函数法进行综合评价.结果 100.0 mg·L-1赤霉素和50.0 mg·L-1硝普钠有利于提高黄芪种子发芽率;50.0 mg·L-1赤霉素和50.0 mg·L-1硝普钠对于提高黄芪种子发芽势效果较好;100.0 mg·L-1赤霉素和10.0 mg·L-1水杨酸对提高种子活力指数效果最佳;10.0 mg·L-1和100 mg·L-1水杨酸可显著增加黄芪种子的根长;50.0 mg·L-1赤霉素可显著增加芽长.结论 促进黄芪种子萌发效果最佳外源物质为赤霉素,浓度为100.0 mg·L-1和125.0 mg·L-1均可显著促进黄芪种子的萌发.

The genus Falsomesosella Pic,1925 currently includes two subgenera,with 36 species/subspecies described in the nominate subgenus(Tavakilian&Chevillotte,2021).Among them,10 species were recorded from China(Lin&Tavakilian,2019).Recently,Lazarev(2021)describ
马铃薯是中国膳食结构中的重要组成成分,具有很高的营养价值,有着“营养之王”的称号.不同加工方式对马铃薯的营养成分的影响不同,为了进一步系统的了解不同加工方式对马铃薯营养物质的变化,为马铃薯的加工升级提供依据,本文综述了马铃薯的营养物质,以及炒、蒸、微波和煮制等几种常见的加工方式对马铃薯营养成分的影响,为马铃薯产品开发以及工业化提供一定理论参考.

为了帮助高校档案管理政策制定者发现现有政策的不足之处,并为政策的进一步完善提供参考,基于PMC指数模型,构建面向高校档案管理政策的量化评价模型.通过文本挖掘方式,以山西省档案局发布的《关于加强和改进新形势下高校档案工作的实施意见》为例展示本模型的使用过程.研究结果表明,该政策在政策时效、政策受体、政策功能等方面考虑全面,保障措施方面存在不足.有效展示了PMC指数模型对于政策的有效评价,并对新政策的制定或原有政策的修改具有一定的指导借鉴作用.
