摘要
以‘洛阳红’为对照,‘实生苗’、‘玫瑰红’、‘桃花三转’、‘紫冠玉珠’、‘紫楼闪金’为试材,采用蒽酮比色法测定低温处理下叶片可溶性糖含量,研究低温对几种引种紫斑牡丹叶片可溶性糖含量的影响,为抗寒品种的筛选提供一定的试验依据。结果表明:低温对不同品种紫斑牡丹可溶性糖含量产生影响。紫斑牡丹叶片可溶性糖含量在对照与试验品种间、同一品种不同低温条件下均存在显著差异,并且在一定的温度范围内随着温度的降低而升高。不同品种牡丹可溶性糖含量增幅达最大时所处的温度不同。研究初步证明试验种抗寒能力均高于‘洛阳红’。其中‘实生苗’、‘紫楼闪金’、‘玫瑰红’、‘紫冠玉珠’抗寒能力较强,‘桃花三转’抗寒能力较弱。
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 poiysaccharide 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.
