纳米酶处理下大麦子粒功能成分及农艺性状与产量的相关性分析OA

To investigate the effects of grain functional components and agronomic traits on yield in two barley varieties(Hordeum vul-gare L.)under nanozyme treatment,Baosi 27 and Yunpimai 511 were used as experimental materials.The effects of functional compo-nents(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.
