抗种粒斑驳品种东农８１—４３、铁６９１５和感种粒斑驳品种合丰２５、丰收１２在人工接种两个ＳＭＶ株系后，对种粒中总多酚和总黄酮的含量进行了测定。抗种粒斑驳品种由于抗种粒斑驳基因的表达作用，总多酚和总黄酮在感染初期的增长导致了负反馈抑制作用，使后期呈现负增长。感种粒斑驳品种种皮初期总多酚和总黄酮大幅度增加，这种趋势一直保持到后期。类黄酮在种皮上的积累为形成斑驳构成了物质基础。成熟种子种皮中类黄酮配基的组成和含量变化与抗种粒斑驳的抗性相关。
Anti-seed mottled varieties Dongnong 81-43, Tie 6915 and susceptible grain mottle Hefeng 25, bumper harvest 12 After total inoculation of two SMV strains, the content of total polyphenols and total flavonoids in the seed were determined . Antibacterial mottle variety As a result of the expression of anti-seed mottle gene, total polyphenols and total flavonoids in the initial stage of infection led to the negative feedback inhibition, the latter showed a negative growth. Seed germination grain mottled varieties of early skin total polyphenols and total flavonoids increased significantly, this trend has been maintained to the late. The accumulation of flavonoids on the seed coat constitutes the material basis for the formation of mottle. Changes in the composition and content of flavonoid ligands in the seed coat of mature seeds are associated with resistance to germplasm mottle.
