摘要: 为了探究纳米酶处理下2种大麦(Hordeum vulgare L.)子粒功能成分和农艺性状对产量的影响,以保饲27和云啤麦511为材料,考察4种纳米酶施用水平(体积分数分别为0、15.0%、22.5%和30.0%)下子粒总黄酮、γ-氨基丁酸(GABA)、总多酚、蛋白质、还原糖等功能成分与株高、穗长、株重、小穗数、穗粒数、穗粒重、分蘖数等农艺性状对大麦产量的影响。结果表明,不同体积分数纳米酶处理下2种大麦的子粒功能成分、部分农艺性状和产量均有显著差异,以22.5%纳米酶施用水平表现最佳。经相关性分析和通径分析可知,保饲27的功能成分中,总多酚、蛋白质与还原糖是影响其产量的主要因素;云啤麦511的功能成分对产量无显著影响。保饲27的农艺性状中,株高、株重、穗粒重是影响其产量的主要因素;云啤麦511的农艺性状中,穗长与穗粒重是影响其产量的主要因素。

Abstract: To investigate the effects of grain functional components and agronomic traits on yield in two barley varieties (Hordeum vulgare L.) under nanozyme treatment, Baosi 27 and Yunpimai 511 were used as experimental materials. The effects of functional components (total flavonoids, γ-aminobutyric acid (GABA), total polyphenols, protein, and reducing sugars) and agronomic traits (plant height, spike length, plant weight, spikelet number, grain number per spike, grain weight per spike, and tiller number) on barley yield were examined under four nanozyme application levels (volume fractions of 0, 15.0%, 22.5%, and 30.0%). The results showed significant differences in grain functional components, partial agronomic traits, and yield of the two barley varieties under different nanozyme treatments, and the application level of 22.5% nanozyme performed the best. Correlation analysis and path analysis showed that total polyphenols, protein and reducing sugar were the main factors affecting the yield of Baosi 27. The functional components of Yunpimai 511 have no significant effect on yield. Among the agronomic traits of Baosi 27, plant height, plant weight and grain weight per spike were the main factors affecting its yield. Among the agronomic traits of Yunpimai 511, spike length and grain weight per spike were the main factors affecting its yield.

Key words: barley (Hordeum vulgare L.), nanozyme, grain functional components, agronomic traits, yield, correlation
