摘要
[目的]明确天人菊种子萌发阶段和胚芽、胚根生长阶段对NaCl和Na_(2)SO_(4)盐胁迫的耐受性。[方法]以天人菊种子为试材,研究0、20、40、60、80、100、120、140 mmol/L NaCl和Na_(2)SO_(4)盐胁迫对其种子萌发的影响。[结果]天人菊种子萌发阶段对NaCl和Na2SO4的耐盐半致死浓度分别为154.70 mmol/L和99.77 mmol/L,而胚芽生长阶段和胚根生长阶段对Na Cl和Na_(2)SO_(4)耐盐半致死浓度分别为79.68、63.35 mmol/L和105.56、60.24 mmol/L。[结论]该研究可为盐碱地区引种栽培天人菊提供参考依据。
[Objective]The aim of this study was to determine the tolerance of Gaillardia pulchella Foug.at seed germination stage,germ and radicle growth stage under NaCl and Na_(2)SO_(4)stress.[Method]Taking the Gaillardia pulchella seed as materials,the effects of Na Cl and Na_(2)SO_(4)with different concentrations(0,20,40,60,80,100,120 and 140 mmol/L)on seed germination were studied.[Result]The salt tolerance half lethal concentrations of Gaillardia pulchella to NaCl and Na2SO4were 154.70 mmol/L and 99.77 mmol/L during the seed germination,respectively.While the salt tolerance half lethal concentrations to Na Cl and Na_(2)SO_(4)at germ and radicle growth stage were 79.68,63.35 mmol/L and 105.56,60.24 mmol/L,respectively.[Conclusion]The research provided a reference basis for the introduction and cultivation of Gaillardia pulchella in saline-alkali areas.
