摘要：

为了给滨海盐碱地发展芦笋产业以及芦笋耐盐品种的选育提供参考，设置了0%、0.1%、0.2%、0.3%、0.4%、0.5% 6个NaCl盐度水平，对11份芦笋种质材料种子的发芽率和幼苗的生育指数进行了测定和分析。结果表明，芦笋不同品种耐盐能力差异明显，从种子发芽情况看，NJ956、06-9耐盐能力最强，在0.5%盐浓度下仍能正常发芽，其次为NJ982、‘阿波罗’，能耐0.4%的盐浓度，‘冠军’和06-6能耐0.2%~0.3%的盐浓度；从幼苗生长情况看，‘硕丰’耐盐能力最强，其次为06-9、NJ982、‘阿波罗’、NJ956、NJ978和‘冠军’。综合种子发芽和幼苗生长情况，06-9、NJ982、‘阿波罗’、NJ956、NJ978、‘冠军’和‘硕丰’能耐0.3%或更高浓度的NaCl胁迫，可以作为耐盐品种种质材料。

Abstract:

In order to provide references for development of asparagus industry in coastal salt-affected land, and then breed and select salt-tolerant asparagus variety, germination rate and seedling fertility index of 11 asparagus germplasm materials in NaCl stress were analyzed in article. The results showed that: different varieties of asparagus had different salt tolerance ability. From the perspective of germination rate, ‘NJ956’, 06-9 could germinate in 0.5% salt concentration still, were the best; and ‘NJ982’ and ‘Appollo’ could hold 0.4% salt concentration followed; ‘Champion’ and 06-6 could endure 0.2%-0.3% salt concentration only. From the perspective of seedling growth, ‘Shuofeng’ was the best in salt-tolerance, and followed by 06-9, ‘NJ982’, ‘Appollo’, ‘NJ956’, ‘NJ978’ and ‘Champion’. Synthetized asparagus germination rate and seedling growth in salt stress, 06-9, ‘NJ982’, ‘Appollo‘, ‘NJ956’, ‘NJ978’, ‘Champion’ and ‘Shuofeng’ could tolerate 0.3% even higher salt-stress, were suitable for salt tolerance germplasm materials.
