摘要:
以4个品种切花金鱼草为试材，研究了不同低温处理对其叶片可溶性蛋白质含量、可溶性糖含量、游离脯氨酸含量、超氧化物歧化酶(SOD)活性的影响，探讨不同品种金鱼草对低温胁迫的响应特性和耐寒适应能力。结果表明：在不同低温胁迫下，切花金鱼草叶片可溶性蛋白质含量、可溶性糖含量在10～-10℃范围先升后降，但各品种间升高降低的幅度不同；4个品种切花金鱼草叶片游离脯氨酸含量变化与可溶性蛋白质含量一致；随着低温胁迫的加强，植物体内的保护酶SOD活性变化呈现先上升后下降的趋势，但不同品种酶活性下降后仍能维持高于CK的酶活性水平；品种的抗寒性顺序为“将军”粉红双色（A2）>“将军”紫色（A1）>“卡丽玛”粉色（C2）>“卡丽玛”黄色（C1）。
Abstract:
Taking 4 cultivars of cut-flowers Antirrhinum majus as material，the effects of low temperature stress on soluble protein content，solube sugar content，proline content，SOD activities of plant leaves were studied.The results showed that the contents of soluble protein and sugar increased at the beginning and declined afterwards in the range of 10～-10℃.The changes of 4 cultivars of cut-flowers Antirrhinum majus were different in amplitude and procedure.The proline content changes were the same as soluble protein.The activity of SOD became higher at the beginning of stressing and lower later on.The enzyme activity decresed，but they still remained at a high level.It was concluded through these physiological and biochemical characteristics that the cold resistant ability of 4 cultivars of cut-flowers Antirrhinum majus was ‘Admiral’ pink (A2)>‘Admiral’ purple (A1)>‘Calima’ pink(C2)>‘Calima’ yellow (C1).
