基于模糊隶属函数法评价苦荞不同栽培品种种子质量
|
摘要
以分别采收于云南、青海的12个常规苦荞品种为试验材料,运用模糊隶属函数法分析其种子的千粒重、纯度、穗萌发率、发芽率、发芽势、发芽指数、活力指数及平均发芽时间,并评价其种子质量。结果显示:青海和云南的12个品种纯度均高于96%;青海的10个品种千粒重大于20 g,云南的只有6个品种千粒重大于20 g;青海有5个品种存在穗萌发现象,云南有9个品种存在穗萌发现象,其中穗萌发最严重的是‘六苦04’,两地种子穗萌发率均在4. 0%以上;贮藏半年后,青海采收的‘黔苦6号’、‘黔苦5号’、‘苦荞1307-893’、‘晋苦荞6号’、‘云荞2号’、‘六苦04’、‘云荞1号’、‘川荞3号’、‘酉苦1号’和‘晋苦荞2号’仍具有种用价值,而采自云南的‘黔苦6号’和‘六苦04’则失去种用价值。结论:模糊隶属函数法可用于苦荞种子质量分析,多数苦荞品种在青海种植时种子质量更佳,采自云南的‘酉苦1号’表现最好,两地种植时评分均较高的品种为‘晋苦荞2号’和‘酉苦1号’。
To evaluate the quality of seeds,12 tartary buckwheat varieties harvested from Yunnan and Qinghai respectively,were detected thousand-seed-weight,purity,pre-harvest sprouting( PHS),germination percentage,germination energy,germination index and vigor index,mean germination time of seeds,then analyzed by fuzzy subordinate function method. Results showed that the purity of all the samples were higher than 96%; Thousand seed weight of 10 varieties from Qinghai and 6 from Yunnan were more than 20 g; There were 5 varieties from Qinghai and 9 varieties from Yunnan occurred PHS,therein,Liuku 04 had the most serious PHS( > 4%). After storage for half a year,from Qinghai including ‘Qianku 6',‘Qianku 5',‘Kuqiao1307-893',‘Jinku 6',‘Yunqiao 2',‘Liuku 04 ',‘Yunqiao 1',‘Chuanqiao 3',‘Youku 1'and ‘Jinku 2'still had seed values,while seeds of‘Qianku 6'and ‘Liuku 04'from Yunnan lost seed value. Conclusion: Fuzzy subordinate function method can be used to evaluate the quality of seed of tartary buckwheat,most of the varieties from Qinghai had better seed quality,‘Youku 1'harvested from Qinghai got the highest score,‘Jinku 2‘and‘Youku 1'both from Yunnan and Qinghai get higher score.
