摘 要: | 分别用0、50、100、150、200、250、300mmol/L的NaCl溶液对3种菊苣种子进行处理,并对发芽率、发芽势、根长、苗长和鲜重等生理指标进行研究。结果表明:种子萌发率与NaC1浓度呈明显的负相关。150mmol/L的NaCl浓度为菊苣种子耐盐半致死浓度,250mmol/L的NaCl浓度为菊苣种子耐盐极限浓度。100mmol/L的NaCl对菊苣种子萌发后的生长影响显著。

Abstract: | Solutions of NaCl concentration of 0 mmol/L , 50 mmol/L , 100 mmol/L , 150 mmol/L , 200 mmol/L , 250 mmol/L , 300 mmol/L were used to handle the three chicory seeds , the physiological indicators such as germination rate , germinability , root length , seedling length and fresh weight of chicory were studied.Results indicated that seed germination rate and concentration of NaCl showed a significant negative correlation. 150 mmol/L NaCl was semi-lethal salt concentration for chicory seeds. 250 mmol/L NaCl was the limit salt concentration for chicory seeds. The effect of 100 mmol/L NaCl on the growth after seed germination of chicory was significant. |
