以兴高采烈、紫海银波、红珍珠3个引进的.索斑牡丹品种为试验材料,在哈尔滨冬季自然降温条件下(稳定降至-5～-10℃开始,每降5℃取样一次,至温度降到-25～-30℃),测定越冬枝条的可溶性糖、可溶性蛋白、脯氨酸含量及SOD活性变化.结果表明,随着温度的降低,3个品种的各项指标测定结果都有不同程度的增加.且兴高采烈和紫海银波的各项指标测定值高于红珍珠,即兴高采烈和紫海银波表现为相对较强的抗寒特性.
이흥고채렬、자해은파、홍진주3개인진적.색반모단품충위시험재료,재합이빈동계자연강온조건하(은정강지-5～-10℃개시,매강5℃취양일차,지온도강도-25～-30℃),측정월동지조적가용성당、가용성단백、포안산함량급SOD활성변화.결과표명,수착온도적강저,3개품충적각항지표측정결과도유불동정도적증가.차흥고채렬화자해은파적각항지표측정치고우홍진주,즉흥고채렬화자해은파표현위상대교강적항한특성.
The article used the three species of Paeonia rockii that introduced as experiment mate-rials, they were Xinggaocailie, Zihaiyinbo and Hongzhenzhuo Lower temperature at natural conditions in winter of Harbin (when the temperature degraded at-5～-10℃, we began to sample every 5℃ for one time, until the temperature degraded at -25～-30℃), we determined the changes of their soluble sugar, soluble protein, Pro and SOD. The results showed that each indicators of these species had different degrees of increase, the result of Xinggaocailie and Zihaiyinbo was higher than that of Hongzhenzhu and showed colder hardiness.
