摘要
为了建立寒地粳稻耐碱评价指标体系,筛选出适宜苏打盐碱地种植的寒地粳稻种质资源,本研究采用混合碱胁迫处理70份寒地粳稻种质,研究混合碱对寒地粳稻萌发期芽长、根长、芽干重、根干重等指标的影响,并以各单项指标耐碱系数作为评价芽期的耐碱性依据,利用相关分析及模糊数学中的隶属函数法对寒地粳稻材料进行耐碱性综合评价。结果表明:通过隶属函数法对不同寒地粳稻材料进行耐碱排序,将70份粳稻种质分为四大类,其中有14份粳稻材料属于强耐碱、31份粳稻材料属于耐碱、24份粳稻材料属于中度耐碱、1份粳稻材料属于敏感品种。
In order to establish an evaluation index system for the alkali tolerance of japonica rice in cold region,the germplasm resources of cold region japonica rice suitable for planting in soda saline-alkali land were selected.Using mixed alkali stress to treat 70 cold region japonica rice germplasms,the effects of mixed alkali on the bud length,root length,bud dry weight,root dry weight and other indexes of cold region japonica rice at the germination stage were studied,and the individual index alkali tolerance coefficient was used for the evaluation.Based on the alkali tolerance at the bud stage,the correlation analysis and the membership function method in fuzzy mathematics were used to comprehensively evaluate the alkali tolerance of cold-land japonica rice materials and cluster analysis.The results showed that 70 japonica rice germplasms were divided into four major categories by using the membership function method to sort the japonica rice materials in different cold regions,of which 14 japonica rice materials were highly salt-tolerant and 31 japonica rice materials were salt-tolerant 24 japonica rice materials were moderately salt-tolerant and 1 japonica rice material was a sensitive variety.
