采用MS培养方法,分别用不同浓度NaCl和NaHCO3(0、10、20和30mmol·L-1)对二倍体马铃薯试管苗进行胁迫,研究了3个耐盐(NaCl)无性系试管苗受NaHCO3胁迫时的生长状况。结果表明:当采用NaCl处理时,随着胁迫强度的增加,这3个二倍体无性系芽和根长及其鲜样质量和干样质量6个生长参数呈先升高后降低的趋势,NaHCO3处理时,这6个生长参数呈降低的趋势,降低幅度大于NaCl处理。同一浓度下,同一材料受NaHCO3伤害作用远大于NaCl伤害。
The diploid potato seedlings were inoculated with different concentrations of NaCl and NaHCO3 (0, 10, 20 and 30 mmol·L-1) respectively using MS culture method. Three salt-tolerant (NaCl) The state of growth during stress. The results showed that when NaCl stress was applied, the growth and root length of the three diploid clones and the six growth parameters of fresh-like and dry-like qualities tended to increase at first and then decrease with the increase of stress intensity. NaHCO3 treatment, the six growth parameters showed a downward trend, the reduction rate is greater than the NaCl treatment. Under the same concentration, the damage of the same material to NaHCO3 was much greater than that of NaCl.
