Abstract:
Taking three-year-old Euonymus japonicus ‘Zhuzi’,Euonymus kiautschovicus and the hybrid seedlings as materials，the changing of contents of soluble sugar，starch and protein during the winter were studied.The results showed that during the winter，the contents of soluble sugar decreased firstly，then increased，and decreased lastly，starch in contrast.The content of soluble sugar and starch in hybrid and Euonymus japonicus ‘Zhuzi’ was higher than Euonymus kiautschovicus’s，and the protein in Euonymus japonicus ‘Zhuzi’ was significantly higher than the other two species.The content of fructose was higher than glucose，and was more distinguished in hybrid.The three species had different mechanisms of cold.The hybrid had a stronger cold hardiness than its parents.
