摘　　要：种子萌发是种群定居的关键阶段,盐生植物的种子萌发策略是影响植物种在盐渍环境中定居与分布的重要因素。黎科猪毛菜属是盐生植被的主要建群种,能忍受贫瘠、干旱的生境,是新疆种类最多、分布最广的植物类型之一。文章数据集是在实验室内基于生理生态学的原理,以种子萌发特性为研究目标,研究2017年10月中旬采于新疆准噶尔盆地的东方猪毛菜、木本猪毛菜和钠猪毛菜无翅种子在不同变温(2~5℃、5~15℃、5~25℃和15~25℃,光/暗交替,12 h/12 h)、盐胁迫变化(0、100、200、300和400 mmol/L NaCl溶液盐胁迫)及复水后的萌发实验数据基础上整理而来;并随机抽取有翅和无翅钠猪毛菜种子若干,分别测得其直径和千粒重。本数据集对干旱区猪毛菜植被恢复、引种驯化和开发利用有重要的实践和指导意义。Seed germination is a key stage of population settlement,and the seed germination strategy of saline plants is an important factor affecting the settlement and distribution of plant species in saline environments.The Chenopodiaceae Salsola L.is a major population-building species of saline vegetation that can tolerate poor and arid habitats,and is one of the most diverse and widely distributed plant types in Xinjiang.This dataset is based on the principle of physiology and ecology in the laboratory,aiming at the characteristics of seed germination.The germination data of wingless seeds of S.rigida Pall.,S.arbuscula Pall.and S.nitraria Pall.collected in mid-October 2017 in the Junggar Basin,Xinjiang were studied under the different temperatures(2-5,5℃-15,5℃-25℃and 15-25,12℃-hour light/dark alternation),salt stress(0,100,200,300 and 400 mmol/L NaCl)and rehydration.A number of winged and non-winged Salsola L.seeds are randomly selected,and their diameters and 1000-grain weights are measured respectively.This dataset has important practical and guiding significance for the restoration,introduction and domestication of Salsola L.vegetation and development and utilization in arid areas.
