| 摘 要： | 为更好地开发和利用地木耳,探讨了不同浓度的NaCl、NaNO3、Ca(NO3)2对地木耳生物量积累和胞外多糖产生的影响。结果表明:NaCl和NaNO3诱导子在低浓度时起促进作用,高浓度时抑制地木耳的生长和胞外多糖的产生,均以20 mmol/L浓度为最佳的诱导条件;而Ca(NO3)2随浓度的增加生物量和多糖含量上升,80 mmol/L诱导作用效果最好。

| Abstract: | Effect of different concentrations of NaCl,NaNO3 and Ca(NO3)2 on biomass accumulation and EPS secretion of N.commune were studied to develop and utilize N.commune preferably.The results showed that the elicitors of NaCl and NaNO3 can promote plant growth and EPS secretion in lower concentration while inhibit in higher concentration.The optimum condition of elicitor is 20 mmol/L.The biomass and EPS content increase with the increase of Ca(NO3)2 concentration and 80 mmol/L Ca(NO3)2 has the best effect. |
