- 摘要:
- 以3年生中国水仙鳞茎球为试材，设计不同浓度的铜离子处理，在相同处理时间内测定水仙的生长形态与保护酶活性，研究不同浓度的铜离子处理对水仙生长发育的影响，分析水仙植株对铜离子胁迫的抵抗能力，以期为重金属污染修复提供理论依据。结果表明：在浓度为45 μmol/L的铜离子处理下，水仙无明显的徒长阶段，植株株型紧凑坚挺矮小，没有出现倒伏现象，叶色浓绿，叶肉较厚，并且水仙的抽薹、开花正常，达到一定的水仙植株矮化效果。
- Abstract:
- Taking bulbs of Zhangzhou Narcissus tazetta as experiment materials，the effect of copper stress on development of Narcissus plants were studied，the stress resistance were analyzed with a view on Narcissus dwarfing effect and heavy metal contaminated,the bulbs were treated with a series concentration of copper ion at the same time.The results showed that under the treatment with the concentration of 45 μmol/L copper ion，the effect of dwarfing was better than other treatments. Significant spindling stage wasn’t observed，and plant type showed strongly short without lodging phenomenon. The color of leaves was dark green and leaf showed thickness. The bolting and blossom weren’t affected under 45 μmol/L copper ion treatment. The results showed that 45 μmol/L copper ion treatment was suitable for dwarfing.
