摘要:
在建立测定青钱柳(Cyclocarya paliurus)中β谷甾醇含量方法的基础上,探讨了不同温度对3个青钱柳种源1年生苗木中β谷甾醇含量的影响。结果表明:不同温度对青钱柳苗茎中β谷甾醇的含量影响显著,而对叶片和根中β谷甾醇的含量影响不显著(p<0.05)。在30、25和20 ℃条件下,青钱柳苗茎中β谷甾醇平均质量分数分别为1.50 %、0.92 %和1.72 %;不同器官青钱柳β谷甾醇含量有差异性,以叶的含量为最高,茎次之,根的含量最低。温度和种源交互作用对青钱柳根部、叶片β谷甾醇含量的影响极显著。相对的高温和低温都有利于青钱柳根和茎中β谷甾醇的合成,但叶中的含量以在25 ℃时最高。
Abstract:
Based on the establishment of measuring method of β sitosterol content in Cyclocarya paliurus, the effect of different temperatures on β sitosterol content in oneyear old seedlings of three C. paliurus provenances was studied in the paper. The results showed that temperature had a significant influence on the β sitosterol content in the stems of C. paliurus seedling, while no significant effects were observed in the root and leaves. The average contents of β sitosterol in stems of C. paliurus seedlings were1.50 % for 30 ℃, 0.92 % for 25 ℃ and 1.72 % for 20 ℃ respectively. There were significant differences in β sitosterol content at different tissue organs of C. paliurus. The highest content was observed in leaves, followed by stems, and the lowest was detected in roots. A significant interaction between temperatures and provenances was founded in the β sitosterol contents of C. paliurus roots and leaves. The results from this study suggested that both higher temperature and lower temperature would improve the content of βsitosterol in the roots and stems of C. paliurus seedlings, but the highest contents of leaves were achieved at 25 ℃.
