NaCl胁迫对籽粒苋种子萌发的影响
- Title:
- Effects of NaCl Stress on Seed Germination of Amaranthus hypochondriacus

- 摘要:
- 为了筛选出耐盐籽粒苋种质资源，采用滤纸培养法，测定了不同浓度NaCl溶液处理下4份籽粒苋种子的发芽率、发芽势、发芽指数、活力指数、相对盐害率和全株长，分析了不同盐胁迫下4个品系籽粒苋种子的平均隶属函数值。结果表明：随NaCl溶液浓度的增加，4份籽粒苋种子的发芽率、发芽势、发芽指数、活力指数以及全株长度均呈下降趋势，相对盐害率呈上升趋势。低浓度盐胁迫（50 mmol·L-1）对LX014、LX022品系发芽率无显著影响，而当盐浓度≥100 mmol·L-1时，所有籽粒苋品系的种子萌发指标均显著下降，相对盐害率显著提高，种子盐胁迫效应明显加重。通过平均隶属函数值对4种籽粒苋品系材料种子耐盐性进行综合评价认为，LX014品系耐盐性最强，其次是LX022，而LX006和LX019耐盐性差。
- Abstract:
- In order to select salt-tolerant Amaranthus hypochondriacus germplasm resources,filter paper culture method was adopted and four Amaranthus hypochondriacus lines were used as materials,the effect of different concentrations of NaCl (0,50,100 and200mmol·L-1) on the seed germination characteristics,including germination rate,germination energy,germination index,seed vigor index,relative salt injury rate and whole plant length were studied and the average membership function values of four seeds under different NaCl stress were analyzed.The results showed that with the increase of salt solution concentration,the germination rate,germination energy,germination index,seed vigor index and the whole plant length of the four materials all decreased,and the relative salt damage rate increased.Low-concentration salt stress (50 mmol·L-1) had no significant effect on the germination rate of the LX014 and LX022.However,when the salt concentration was 100 mmol·L-1,the seed germination index of all varieties decreased significantly,the relative salt injury rate increased significantly,and the seed salt stress effect was significantly intensified.By comprehensive evaluation of the average membership function value,we concluded that LX014 had the strongest salt tolerance,followed by LX022，LX006,LX019 have the poorest salt tolerance.
