以M0901-2-2-5(1#)等9个结球甘蓝为试验材料,研究不同浓度NaCl对甘蓝种子发芽率及幼苗根长、苗长的影响。结果表明,随NaCl浓度增大,9个结球甘蓝品种的种子发芽率逐渐降低,其幼苗的根长、苗长逐渐变小;NaCl处理浓度与M0901-2-2-5、ZS-2-1-3-3(7#)、0905-1-12-2-5(8#)、G013-2-3(9#)这4个甘蓝种子的发芽率及幼苗根长、苗长有一定的负相关性,NaCl对甘蓝幼苗根的抑制作用强于苗;不同甘蓝品种对NaCl溶液的耐受能力不同,品种ZS-2-1-3-3、G013-2-3的耐盐性能相对最佳;0.2%NaCl浓度处理对ZS-2-1-3-3根、0905-1-12-2-5幼苗生长有促进作用。
Nine cabbage varieties, M0901-2-2-5 (1 #), were used as experimental materials to study the effects of different concentrations of NaCl on the germination rate of cabbage seeds and root length and seedling length. The results showed that with the increase of NaCl concentration, the seed germination rate of 9 cabbage varieties decreased gradually, and the root length and seedling length of seedling decreased gradually. The NaCl concentration was significantly lower than that of M0901-2-2-5, ZS-2- The seed germination rate and the root length and seedling length of the four cabbage seeds 1-3-3 (7 #), 0905-1-12-2-5 (8 #) and G013-2-3 (9 #) , The inhibitory effect of NaCl on cabbage seedling roots was stronger than that of seedlings. The tolerance ability of different cabbage varieties to NaCl solution was different, and the salt tolerance of ZS-2-1-3-3 and G013-2-3 was relatively 0.2% NaCl treatment could promote the growth of seedlings of ZS-2-1-3-3 root and 0905-1-12-2-5.
