- 摘要:
- 以常用草坪种剪股颖为试验材料，通过室内萌发试验，研究了足量供水和限量供水条件下，不同施用量的保水剂对剪股颖种子萌发的影响。结果表明：足量供水条件下，不同用量的保水剂对高羊茅种子萌发均无影响；限量供水条件下，施用适量保水剂对剪股颖种子的发芽率、发芽势、萌发指数和根生长速度有明显促进作用。表明不同水分条件下，保水剂对剪股颖种子萌发的作用不同，且其对剪股颖种子萌发的促进作用与施用剂量有关。
- Abstract:
- Taking Agrostis stolonifera L. as test material,germination experiment was performed,in order to investigate the effect of water retaining agent on seed germination in Agrostis stolonifera L..Different dose of water retaining agents were added into culture dishes under the conditions of sufficient water and limited water,and the effect of water retaining agents on seed germination was analyzed subsequently.The results showed that different dose of water remaining agenthad no significant effect on seed germination under the condition of sufficient water.However,the appropriate dose of water retaining agent significantly improved the germination rate,germination energy,germination index and growth rate of root under the condition of limited water.The results indicated that water retaining agent had different roles under different water condition,and the improved roles of water retaining agent on seed germination in bentgrass depend on the dose of water retaining agent.
