摘　　要：以不同块茎颜色马铃薯品种陇薯8号、陇薯7号、LC310-2和山东彩肉为材料,研究外源NO、H2O2、NO+H2O2处理对马铃薯块茎花青素合成及其信号物质Ca2+-ATPase和CaM的影响。结果表明:外源NO和H2O2处理后,4个基因型马铃薯薯皮和薯肉花青素积累,Ca2+-ATPase活性升高,CaM含量增加,其效果为NO+H2O2>H2O2>NO>水(CK),并且花青素的积累量与Ca2+-ATPase活性和CaM含量均呈正相关,其平均决定系数达0.9194和0.8859。说明NO和H2O2对马铃薯花青素合成具有一定的促进作用,而细胞Ca2+/CaM信号发挥了NO和H2O2对马铃薯花青素合成诱导的信号调节。Taking different colors potatos（Solanum tuberosum L.）＇Longshu No.8＇,＇LongshuNo.7＇,＇LC310-2＇ and ＇Shandongcairou＇ as materials,this experiment studied on anthocyanin accumulation and related signal mater Ca^2＋-ATPase and CaM of potato tuber after treatment of water（CK）,NO,H2O2,NO＋H2O2.The results showed that,the anthocyanin accumulated in 4 gene-types potatoes,Ca^2＋-ATPase activity increased,CaM content enhanced after exogenous NO and H2O2 treatments.The inductive effect was NO＋H2O2H2O2NOCK.Moreover,anthocyanin accumulation was related with Ca^2＋-ATPase activity increasing and CaM content enhance,and its related index was 0.9194 and 0.8859.It indicated that NO and H2O2 had a certain role in promoting the potato anthocyanin synthesis,and intracellular Ca^2＋/CaM signal play signal transduction in NO and H2O2 inducing potato anthocyanin synthesis.
