为荞麦在盐渍化地区的应用提供参考，比较了添加不同浓度谷氨酸和天冬氨酸对盐胁迫荞麦种子萌发及幼苗生长的影响。结果表明：在100 mmol/L NaCl胁迫下，川荞3号添加30μmol/L谷氨酸的发芽率、发芽指数、幼苗根长、幼苗鲜重、幼苗根系活力和幼苗叶片的叶绿素含量为该组合组最高，分别为82．34％、10．85、2．52 cm、1．109 g、87．58 U/g FW和0．821 mg/g FW，比盐胁迫处理分别增加38．08百分点、102．05％、82．61％、41．33％、106．02％和59．11％；川荞4号添加40μmol/L天冬氨酸的发芽率、发芽指数、幼苗根长、幼苗鲜重、幼苗根系活力和幼苗叶片的叶绿素含量为该组合最高，分别为93．06％、13．87、3．36 cm、1．421 g、105．16 U/g FW和1．085 mg/g FW，比盐胁迫处理分别增加35．68百分点、109．20％、49．33％、89．21％、95．94％和57．93％。结论，适宜浓度谷氨酸和天冬氨酸对盐胁迫下的荞麦种子萌发及幼苗生长具有促进作用。
為蕎麥在鹽漬化地區的應用提供參攷，比較瞭添加不同濃度穀氨痠和天鼕氨痠對鹽脅迫蕎麥種子萌髮及幼苗生長的影響。結果錶明：在100 mmol/L NaCl脅迫下，川蕎3號添加30μmol/L穀氨痠的髮芽率、髮芽指數、幼苗根長、幼苗鮮重、幼苗根繫活力和幼苗葉片的葉綠素含量為該組閤組最高，分彆為82．34％、10．85、2．52 cm、1．109 g、87．58 U/g FW和0．821 mg/g FW，比鹽脅迫處理分彆增加38．08百分點、102．05％、82．61％、41．33％、106．02％和59．11％；川蕎4號添加40μmol/L天鼕氨痠的髮芽率、髮芽指數、幼苗根長、幼苗鮮重、幼苗根繫活力和幼苗葉片的葉綠素含量為該組閤最高，分彆為93．06％、13．87、3．36 cm、1．421 g、105．16 U/g FW和1．085 mg/g FW，比鹽脅迫處理分彆增加35．68百分點、109．20％、49．33％、89．21％、95．94％和57．93％。結論，適宜濃度穀氨痠和天鼕氨痠對鹽脅迫下的蕎麥種子萌髮及幼苗生長具有促進作用。

In order to provide references for applying buckwheat in salination areas,the effects of adding different concentrations of glutamic acid and aspartic acid on seed germination and seedling growth of buckwheat under salt stress were studied.Results:Under 100 mmol/L NaCl stress,the germination rate,germination index,seedling root length,seedling fresh weight,seedling root vigor and chlorophyll content in seedlings leaves of Chuanqiao 3 adding 30 (mol/L glutamic acid were all the highest,which were 82.34%,10.85,2.52 cm,1.109 g,87.58 U/g FW and 0.821 mg/g FW respectively,and increased by 38.08 percentage points,102.05%,82.61%,41.33%,106.02% and 59.11% respectively compared to salt stress treatment;While that of Chuanqiao 4 adding 40 (mol/L aspartic acid were all the highest, which were 93.06%,13.87,3.36 cm,1.421 g,105.16 U/g FW and 1.085 mg/g FW respectively,and increased by 35.68 percentage points,109.20%,49.33%,89.21%,95.94% and 57.93% respectively compared to salt stress treatment. Conclusion:The appropriate concentrations of glutamic acid and aspartic acid treatment could promote seed germination and seedling growth of buckwheat under salt stress.
