【摘要】 以彩色马蹄莲(Zantedeschia hybrids)品种‘Black Magic’为试材,在6、9、12、1 5℃贮藏0、28、56、84、112 d条件下,研究其块茎的淀粉、可溶性总糖、还原糖含量以及淀粉酶、过氧化物酶(POD)、超氧化歧化酶(SOD)和过氧化氢酶(CAT)的活性变化。结果表明:淀粉含量以及4种酶的活性变化均呈现出随贮藏时间的增加而逐渐下降的趋势;贮藏温度越高,块茎内POD、SOD和CAT酶活性下降越明显;这3种酶活性与块茎萌芽率呈负相关。

【Abstract】 The Calla lily hybrid ’Black Magic’was used as a test material,and variations of its tubers’starch,total soluble sugar and reducing sugar contents,and amylase,peroxidase(POD),superoxide dismutase(SOD)and catalase(CAT)activities were studied under 0,28,56,84 and 112 d storage at 6,9,12 and 15℃.The results indicated that the starch content and the 4 enzyme activities gradually decreased with storage time;the higher the storage temperature,the more obvious the decrease of POD,SOD and CAT activities;and those 3 enzyme activities were negatively correlated to the germination rate of the tubers.
