Abstract:
In this experiment P.suffruticosa ‘ Luo Yang Hong’ was used as a control group, effects of low temperature on soluble polysaccharide in leaves of several introduced P.rockii was researched. Several introduced P.rockii include seedling, ‘Mei Gui Hong’, ‘Tao Hua San Zhuan’, ‘Zi Guan Yu Zhu’, ‘Zi Lou Shan Jin’. Leaves of several tree peony cultivars was treated under low temperature, soluble polysaccharide content were determined by using anthrone colorimetric method ,different soluble polysaccharide content of leaves treating by low temperature were compared among the several tree peony cultivars. The results showed that low temperature could effect on soluble polysaccharide content of leaf. There was significant differences in soluble polysaccharide content between P.suffruticosa and P.rockii, even there were significant differences in the same variety under different temperature condition. Moreover, at some temperature range soluble polysaccharide content was increased with the decrease of the temperature. When the increase amplitude of Soluble polysaccharide content was maximal, diifferent tree peony cultivars was at different temperature. This study preliminary proved that cold resistance of P.rockii were stronger than P.suffruticosa‘ Luo Yang Hong’. Tested cultivars that Cold resistance were relatively strong had been seeding, ‘Mei Gui Hong’,‘Zi Guan Yu Zhu’and‘Zi Lou Shan Jin’. Cold resistance of‘Tao Hua San Zhuan’ were weaker.
