Effects of cultivation temperatures and provenances on β- sitosterol content of Cyclocarya paliurus seedlings
摘要
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 were 1.50 ％ 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 β - sitosterol in the roots and stems of C. paliurus seedlings, but the highest contents of leaves were achieved at 25 ℃.关键词
