| 摘 要： | 以彩色马蹄莲(Zantedeschia hybrids)的Black Magic为试材,研究其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后期植株生长的变化。结果表明,贮藏温度越高,淀粉降解越快;各温度处理总可溶性糖含量与蔗糖含量变化趋势基本一致,9、12、15℃下,贮藏第28天总可溶性糖含量与蔗糖含量达到峰值后明显下降;12℃、15℃贮藏第56天淀粉酶活性达到峰值后明显下降,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。贮藏第56天块茎休眠的打破、萌发与糖类物质变化密切相关。在本试验中,短期贮藏(56 d)以12℃为宜,长期贮藏(112 d)以12℃贮藏56 d再降低至6℃最佳。

| Abstract: | Different temperature treatments on Calla lily were used to study the changes of carbohydrate metabolism in tubers,the germination 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 56 d.Amylase activities decreased as the storage temperature increased.In this period tubers sprouted obvio... |
