禾谷镰刀菌培养滤液对小麦种子萌发代谢的影响

摘要

禾谷镰刀菌培养滤液对小麦萌发代谢影响的研究结果表明：该菌滤液毒素显著影响了小麦种子萌发过程芽和根器官中的可溶性蛋白质、核酸、总糖等主要物质的合成积累代谢；根受到的影响较芽大；萌发种子胚乳α-淀粉酶活性也受到抑制.揭示了禾谷镰刀菌毒素影响小麦种子萌发过程中物质合成代谢和芽根器官建成的生理原因.%The effect of cultured Fusarium graminearum's filtrate ongerminating metabolism of wheat seeds was studied. The results showed that the synthesis and accumulation metabolisms of wheat shoot’ and root’s soluble protein， nucleic acid and gross sugar were affected by Fusarium graminearum’s filtrate during the germination； the affection of shoot was more severe than that of root; the α-amylase activity of germinating seed was inhibited too. the physiological reasons were also analyzed that Fusarium graminearum's filtrate affected wheat seed germination and organ formation.
