摘要:

【目的】研究干旱胁迫对中亚大麦农艺性状和品质的影响,为大麦耐旱育种以及干旱条件下提高产量与品质提供理论依据。【方法】以12个不同抗旱性的中亚大麦种质资源为研究对象,设3个水分处理,测定大麦株高、穗长、穗粒数、千粒重、产量、籽粒总黄酮含量和总多酚含量。【结果】干旱胁迫对测定的指标均有显著影响,其中(1)随着干旱胁迫增加,所有参试材料的株高、穗长、穗粒数、千粒重和产量均呈逐渐下降的趋势;(2)随着干旱胁迫加剧,吉引2013-7-DM-005、吉引2013-7-DM-045、吉引2013-7-DM-072、吉33、吉引2013-7-DM-088总黄酮含量显著升高,吉引2013-7-DM-71、吉引2013-7-DM-046、吉引2013-7-DM-051、吉2、吉35和哈3总黄酮含量先显著升高后降低;除吉引2013-7-DM-051总多酚含量先升高后显著减低,哈3总多酚含量先升高后略减低,其他10个中亚大麦籽粒总多酚含量均表现为显著升高。(3)总黄酮含量与参试大麦产量呈显著正相关,与总多酚含量、株高、穗长、穗粒数呈正相关,与千粒重呈负相关;总多酚含量与穗长和产量呈极显著负相关,与穗粒数呈正相关,与株高和千粒重呈负相关。【结论】干旱胁迫可不同程度的增加中亚大麦籽粒总黄酮和总多酚含量。

Abstract:

【Objective】 To explore the effects of drought stress on the agronomic traits and quality of barley in Central Asia, so as to provide theoretical basis for drought tolerance breeding of barley in China and improve the yield and quality of barley under drought conditions. 【Methods】 12 different drought-resistant germplasm resources of barley in central Asia were taken as research objects and three water treatments of normal irrigation, irrigation with two water and irrigation with one water were designed. The plant height, spike length, grain number per spike, 1,000-grain weight, yield, total flavone content and total polyphenol content in grains were measured. 【Results】 The results showed that drought stress had significant effects on all indexes.(1)With the increase of drought stress, the 1,000-grain weight and yield of all tested materials showed a gradual downward trend. Except cultivar 8 and cultivar 9, the plant height of all tested varieties showed a downward trend, and the ear length of all tested varieties except cultivar 10 and cultivar 11 showed a downward trend.(2)With the aggravation of drought stress, the content of total flavonoids in varieties Jiyin 2013-7 -DM-005, Jiyin 2013-7-DM-045, Jiyin 2013-7-DM-072, Ji33 and Jiyin 2013-7-DM-0881 increased significantly, and the content of total flavonoids in varieties Jiyin 2013-7-DM-71, Jiyin 2013-7-DM-046, Jiyin 2013-7-DM-051, Ji2, Ji 35 and Ha3 increased significantly at first and then decreased; except Jiyin 2013-7-DM-051, the content of total polyphenols increased first and then decreased significantly, the content of total polyphenols in Ha3 increased first and then decreased significantly, the content of total polyphenols in other 10 Central Asian barley grains increased significantly.(3)The content of total flavonoids was significantly positively correlated with yield, but not significantly positively correlated with total polyphenol content, plant height, ear length and grain number per ear, and not significantly negatively correlated with 1,000 grain weight; the content of total polyphenols was extremely significantly negatively correlated with ear length and yield, but not significantly positively correlated with plant height and grain number per ear, and not significantly negatively correlated with 1,000 grain weight. 【Conclusion】 Drought stress could increase the contents of total flavonoids and total polyphenols in barley grains.

Key words: barley from central asia; drought stress; yield; total flavonoids content; total polyphenol content
