摘  要：
[目的]研究不同浓度NaCl和PEG6000对高雪轮、矮雪轮、五彩石竹、须苞石竹、麦仙翁和花园鼠尾草6种花卉种子萌发的影响,了解6种花卉种子对盐碱和干旱的适应性。[方法]对6种花卉种子进行不同浓度NaCl和PEG 6000胁迫处理,研究6种花卉种子在胁迫下的萌发特性。[结果]当NaCl浓度大于200 mmol/L时,明显抑制了高雪轮和矮雪轮种子的萌发;浓度大于300 mmol/L时,明显抑制麦仙翁、五彩石竹、须苞石竹和花园鼠尾草种子的萌发。当PEG6000浓度大于5%时,明显抑制花园鼠尾草种子的萌发;浓度大于20%时,明显抑制高雪轮种子的萌发;浓度大于25%时,明显抑制麦仙翁、须苞石竹、五彩石竹和矮雪轮种子的萌发。[结论]6种花卉种子均可耐重度盐胁迫,麦仙翁、五彩石竹、须苞石竹和花园鼠尾草种子的耐盐性更强;麦仙翁、须苞石竹、五彩石竹和矮雪轮种子的耐旱性强,高雪轮种子的耐旱性较强,花园鼠尾草种子的耐旱性差。

摘  要：
[Objective]To study the effects of different concentration NaCl and PEG6000 on seeds germination of Silene pendula,Silene armeria,Agrostemma githago,Dianthus chinensis,Salvia farinacea,Dianthus chinensis,and obtain the adaptability of six flower seeds to salt and drought. [Method]Different concentrations of NaCl and PEG 6000 stress treatment were conducted on 6 flower seeds,the germination characteristics were studied. [Result]The results showed that: when NaCl solution concentration was more than 200 mmol /L,it inhibited the seed germination significantly in Silene pendula and Silene armeria; when the concentration was greater than 300 mmol /L,it significantly inhibited the seed germination in Agrostemma githago,Dianthus chinensis,Salvia farinacea,and Dianthus chinensis. When the solution concentration of PEG6000 was greater than 5%,it inhibited the seed germination of Dianthus chinensis; when the solution concentration was greater than 20%,it inhibited the seed germination in Silene armeria; when the solution concentration was greater than 25%,it inhibited the seed germination in Agrostemma githago,Dianthus chinensis,Salvia farinacea,and Silene pendula. [Conclusion]Seeds of Agrostemma githago,Dianthus chinensis,Salvia farinacea,Dianthus barbatus have stronger salt tolerance ability; seeds of Silene pendula,Agrostemma githago,Dianthus chinensis,Dianthus barbatus have the strongest drought tolerance ability,seeds of Silene armeria take the second place,and seeds of Salvia farinacea are the poorest.
