自然老化下冬小麦耐贮性评价与分类
Evaluation and Classification of Storage Tolerance of Winter Wheat under Natural Aging
摘要
Abstract
It aims to evaluate the storage tolerance of 20 popular wheat varieties from the Huang-Huai wheat re-gion under natural aging conditions and classify them,thereby providing a theoretical basis for the breeding and se-lection of storage-tolerant wheat varieties.The experiment involved natural aging treatments of 12 and 24 months,with seeds harvested 3 months prior serving as the control.Measurements included seed vigor,seed coat characteris-tics(color and cell membrane integrity),and physiological and biochemical indicators(soluble sugar,gluten pro-tein,starch content,antioxidant enzyme activity,and malondialdehyde content).The results indicated that as aging time increased,seed vigor of all varieties significantly declined.Germination rate and germination potential de-creased by 2.17-10.79 percentage points and 2.80-23.39 percentage points,respectively,after 12 months,and further declined by 15.95-25.88 percentage points and 14.93-41.44 percentage points after 24 months.The hue,saturation,and intensity of seed coat color decreased,while electrical conductivity increased,indicating gradual damage to the seed coat cell membrane.Among the physiological and biochemical indicators,except for malondial-dehyde,soluble sugar,protein,starch content,and antioxidant enzyme activity all showed a declining trend,with greater declines observed after 24 months compared to 12 months.Total starch content exhibited the most significant decrease,declining by 6.43-32.13 percentage points and 21.02-44.95 percentage points after 12 and 24 months,respectively.Based on indicators such as germination rate,seed coat color,electrical conductivity,soluble sugar,and antioxidant enzyme activity,the 20 wheat varieties were classified into storage-tolerant,moderately stor-age-tolerant,and non-storage-tolerant types.Among them,Annong 0711,Luohan 19,and Xinmai 26 demonstrated strong storage tolerance.The findings provide parental materials,evaluation criteria,and theoretical references for the breeding of storage-tolerant wheat varieties.关键词
