Abstract

Abstract:

【Objective】 To investigate the effects of exogenous butyric acid on the growth period, agronomic traits, yield and quality of barley under different drought stress in the hope of providing a theoretical basis for the study of barley drought resistance.【Methods】 Xinpi 4 was used as experimental material.The effects of exogenous butyric acid on the growth period, agronomic traits, yield and quality of barley under drought stress were compared and analyzed by water treatment and γ-aminobutyric acid treatment.【Results】 Exogenous butyric acid seed dressing had no effect on seedling emergence stage and heading stage, but spraying it at flowering stage had a certain effect on maturity stage, and slightly delayed the maturity stage.Under drought stress, seedling emergence stage was not affected, heading stage and maturity stage were advanced.Exogenous butyric acid had no significant difference in basic seedling under drought stress, but had significant difference in maximum total stem number, panicle number and tiller percentage.Plant height, panicle length, panicle grain number and 1000-grain weight increased with exogenous butyric acid treatment.Exogenous butyric acid treatment could improve the yield of barley under drought stress, and the three application techniques of seed dressing, spraying at flowering stage and spraying at seed dressing and flowering stage could reduce the drought loss of barley by 7.0%, 6.3% and 18.3%, respectively.Exogenous butyric acid could increase amylose starch ratio, but has no significant effect on protein content.【Conclusion】 Exogenous butyric acid seed dressing can increase the total number of stem and panicle of barley, while spraying can increase the 1000-grain weight of barley.The yield, drought resistance and amylose ratio of barley under drought stress are improved by seed dressing and spraying at flowering stage.

Key words: barley; exogenous butyric acid; drought stress; agronomic trait; yield

摘要：

【目的】研究外源丁酸对不同程度干旱胁迫下大麦生育期、农艺性状及产量和品质的影响,为大麦抗旱研究提供科学依据。【方法】以新啤4号为材料,采用水分处理和γ-氨基丁酸处理两因素试验设计,比较分析干旱胁迫下外源丁酸对大麦生育期、农艺性状和产量、品质的差异。【结果】外源丁酸拌种处理对出苗期、抽穗期没有影响,开花期喷施对成熟期有一定的影响,成熟期略有推迟。干旱胁迫处理下对出苗期没有影响,抽穗期和成熟期均提前。外源丁酸对干旱胁迫下大麦基本苗差异不显著,对最高总茎数、成穗数、分蘖成穗率差异显著;株高、穗长、穗粒数、千粒重均随着外源丁酸处理而不断增加;外源丁酸处理能提高干旱胁迫下大麦的产量,拌种、花期喷洒、拌种+花期喷洒3种丁酸施用技术,可分别减少大麦受旱损失的7.0%、6.3%和18.3%。外源丁酸可提高直链淀粉的比例,但对蛋白质含量无显著影响。【结论】外源丁酸拌种可增加大麦的总茎数和总穗数,喷洒则可提高千粒重。拌种和花期喷施均可以提高干旱胁迫下大麦的产量、抗旱性和直链淀粉比例。
