【摘要】 以彩色马蹄连(Zantedeschia hybrids)为试材,研究了马蹄莲块茎经不同贮藏温度和时间处理后,块茎碳水化合物代谢及植株生长发育的变化。结果表明:贮藏温度越高,淀粉降解越快;各温度处理蔗糖含量与总可溶性糖含量变化趋势基本一致;贮藏第8w,还原糖含量上升到较高水平,总可溶性糖含量处于较低水平,此阶段块茎萌芽率快速提高,萌芽伸长明显,块茎栽植后株高迅速增高、开花较多。糖分含量的拐点可能与块茎萌发相关。各温度处理淀粉酶活性随贮藏时间增加呈下降的趋势。在本试验中,短期贮藏(8w)以12℃为宜,长期贮藏(16w)以12℃贮藏8w再降低至6℃最佳。更多还原

【Abstract】 Different temperature treatments on Calla lily were used to study the changes of carbohydrate metabolism in tubers,the gerninationg and growth of calla lily.The results indicated that starch content in tubers declined along with the increase of storage temperature,and the changes of sucrose content accorded with that of total soluble sugar,however,the changes of reducing sugar had the opposite trend at 8w.In this period tubers sprouted obviously,and plant height and flower numbers increased.It was suggested that the turning point of sugar contents should be related to the beginning of tuber sprout.Amylase activities decreased as the storage temperature increased.The results indicated that the best treatments of short period storage is at 12℃last for 8w,and long period storage is at 12℃for 8w,then turn to 6℃last for 8w.更多还原
