11份芦笋种质材料耐盐性评价

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。

Evaluation of Salt Tolerance of 11 Asparagus Germplasm Materials

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.
