- 摘要:
- 以白三叶草种子为试材，用ACC9-1脱氨酶促生菌的菌体悬浮液对白三叶草种子进行浸泡处理并用夹板法种植于不同浓度氯化钠胁迫的溶液中(水培)，检测了不同处理下白三叶草的生理、生化指标，比较了促生菌对白三叶草生长的影响。结果表明：随着氯化钠处理浓度的升高，白三叶草幼苗受到的胁迫程度不断增加，当加入促生菌时，胁迫程度降低。说明植物根际促生菌的加入对白三叶草幼苗的盐害有缓冲、调节和适应的作用，因而对降低白三叶草幼苗盐害有重要作用。
- Abstract:
- The seeds of Butch clover were used as experimental materials and were soaked with suspension of bacteria ACC9-1，then the seeds were planted through plate-plate method with different concentration of NaCl solution (Hydroponics).The physical and biochemistry indexes were detected to compare the influencing effects on the growth of Butch cover.The results showed that Butch cover seedlings had a greater damage when the concentration of NaCl was higher.Additionally，if seeds were treated with ACC9-1，the damages decreased a bit.All in all，Butch clover had the capacity of buffering，moderating and adapting to the NaCl stress after adding plant growth promoting bacteria.Therefore，plant growth promoting bacteria could play an important role in reducing damages arise from NaCl in Butch clover.
