摘要: 【目的】研究与评价PEG模拟干旱胁迫下10个藜麦品种的萌芽期抗旱性。【方法】采用5%~30%不同浓度PEG-6000溶液模拟干旱胁迫条件。【结果】低浓度PEG-6000对藜麦种子萌发及根长具有促进作用,对茎长有一定的抑制作用。随着PEG-6000浓度增大,所有抗旱指标均下降。【结论】利用隶属函数分析得出,10个藜麦品种萌发期抗旱性强弱顺序为:YL2>YL1>YL7>YL3>YL9>YL5>YL10>YL6>YL8>YL4。为较好的反映藜麦品种在不同胁迫程度的耐受能力,将10个藜麦品种划分为三个抗旱级别:YL1、YL2、YL7为强耐旱品种; YL3、YL9为中等耐旱品种;YL4、YL5、YL6、YL8、YL10为弱耐旱品种。

Abstract: 【Objective】 Study the drought resistance of 10 quinoa varieties in germination stage. 【Method】In this experiment, PEG-6000 solution with different concentrations of 5%-30% were used to simulate drought stress conditions.【Result】 The results showed that the low concentrations of PEG-6000 promoted seed germination and root length of quinoa and inhibited stem length. 【Conclusion】 According to the analysis of membership function, drought resistance of 10 quinoa varieties at germination stage was: YL2>YL1>YL7>YL3>YL9>YL5>YL10>YL6>YL8>YL4. The quinoa varieties were divided into three drought resistance levels: YL1 , YL2 and YL7 were drought-tolerant varieties,YL3 and YL9 were medium drought-tolerant varieties,YL4, YL5, YL6, YL8 and YL10 were weak drought-tolerant varieties.
