干旱处理对不同抗旱类别小麦品质及种子活力性状的影响
Effects of Drought Treatment on Quality and Seed Vigor Traits of Wheat with Different Drought Resistant Categories
摘要
Abstract
To delve into the effects of drought stress on quality and seed vigor traits of wheat with different drought resistant types,and to provide guidance for improvement of wheat quality and seed vitgor,in this study,17 approved varieties and advanced breeding lines were selected.Two growth conditions were established:drought treatment and normal irrigation.The protein,wet gluten,and starch content of harvested grains were measured using a near-infrared analyzer(DA 7250,Perten).Simultaneously,germination tests were conducted to determine germination potential and germination rate,shoot and root length,shoot and root fresh weight,and shoot and root dry weight.The results indicated that the starch content of grains harvested under normal irrigation was significantly higher than that under the drought treatment.In contrast,protein and wet gluten content,germination potential,germination rate,and shoot length were significantly higher under the drought treatment compared to normal irrigation.Root length,shoot fresh weight,root fresh weight,shoot dry weight,and root dry weight did not show significant responses to the drought treatment.For wheat varieties with different drought resistance levels,the protein and wet gluten content of moderately drought-resistant varieties were significantly higher under the drought treatment than under normal irrigation,while starch content was significantly lower.All of the traits of drought-resistant and drought-sensitive varieties did not show significant differences under the two conditions.However,the root length of drought-resistant varieties was significantly greater than that of moderately drought-resistant and drought-sensitive varieties under both conditions,indicating that drought-resistant varieties exhibited better growth potential and quality stability under drought conditions.In summary,the drought stress treatment significantly improved the traits such as grain protein content,wet gluten content,and seed germination rate in wheat.Furthermore,the response to drought stress exhibited significant variation among wheat varieties of different drought resistant categories in terms of both quality and seed vigor traits.关键词
