中文摘要	谷子是我国北方重要的粮食作物,具有较强的耐盐抗旱能力。盐碱地是我国重要的后备耕地资源,加强谷子种质耐盐评价,筛选耐盐碱的谷子品种对促进盐碱地资源利用、保障国家粮食安全具有非常重要的作用。本试验以63份谷子种质资源为研究对象,以1.0%质量浓度NaCl溶液进行盐胁迫,用蒸馏水作为对照,采用全营养培养基发芽法在人工气候培养箱(昼/夜,30 ℃/20 ℃,光周期14 h/d)中进行谷子种质萌发期的耐盐性鉴定;利用相关性分析和主成分分析明确8项耐盐指标在耐盐性评价中的权重;通过模糊数学中的隶属函数法和聚类分析法对63份谷子种质的耐盐性进行综合评价和耐盐等级划分。结果表明:谷子种质资源的耐盐性存在广泛的变异;1.0%质量浓度的盐胁迫下,谷子的发芽率、发芽指数、根长、芽长、相对芽长、相对根长之间互成极显著正相关关系,而与相对盐害率呈极显著负相关;主成分分析结果表明,发芽率、发芽指数、相对芽长、相对根长可作为谷子耐盐性评价的关键指标;通过聚类分析可将63份谷子种质分为极端耐盐种质、耐盐种质、盐敏感种质和极端盐敏感种质4类;基于模糊数学中的隶属函数得分进行综合评价,筛选获得了济谷16、汾特11号、峰红谷、晋谷57、晋汾106号等5份耐盐谷子品种。
英文摘要	Foxtail millet was an important grain crop in North part of China,with strong salt tolerance and drought resistance.It played an important role in ensuring the food security in arid and barren areas,especially in adjusting and optimizing the agricultural planting structure in saline and alkaline soil which is an important untouched arable land resources in China.In present study,63 accessions of foxtail millet were employed as experimental material,and cultivated in 1.0% salinity regimes of all nutrient medium.The foxtail millets cultivated in all nutrient medium without salinity was designed as control subjects.During the test,all foxtail millets were kept in artificial climate incubator(day/night,30 ℃/20 ℃,photoperiod 14 h/d).Correlation analysis and principal component analysis were employed to evaluate the eight salt tolerance indexs in salt tolerance evaluation.Membership function analysis and cluster analysis were also employed to identify the grade of salt tolerance of foxtail millet.The results showed that:grate variations of salt tolerance was observed among the germplasm of foxtail millet.Under 1% NaCl of salt stress,a significant positive correlation was detected between the germination rate,germination index,root length,germinal length,relative germinal length and relative root length of plant,and the relative salt harm rate showed a significant negative correlation with the above 6 indexes.The results of principal component analysis showed that the percentage of germination rate,germination index,relative germinal length and relative root length were used as major indexes to evaluate salt tolerance of foxtail millet.Cluster analysis indicated that 63 foxtail millet accessions were divided into four groups(highly tolerant,tolerant,sensitive,extreme sensitive).Finally,Fenghonggu,Jinfen 106,Jingu57,Fente11,Jigu 16 were selected as excellent salt tolerant accessions by comprehensive evaluation with the score of membership function in fuzzy mathematics.
