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.
