- 摘要:
- 以雪柳（Fontanesia fortunei Carr.）2 a生实生苗为试材，通过人工模拟连续淹水处理，研究了水淹胁迫对雪柳叶片部分生理指标的影响。结果表明：雪柳对水淹胁迫具有一定的耐受性。水淹组叶绿素(a+b)含量和a/b值与对照组变化趋势基本同步，差异均不显著；至淹水结束时，叶绿素a/b值略高于对照，(a+b)含量低于对照。可溶性糖含量与丙二醛（MDA）含量变化趋势基本一致，先升高后降低，都在21 d达到峰值，至水淹结束时均恢复到对照水平。可溶性蛋白含量水淹前期与MDA含量变化趋势相反，后期则一致，至水淹结束时降为对照的68%。脯氨酸含量与对照相比多数时刻处于积累状态；水淹后期与MDA含量变化趋势一致，水淹结束时降为对照的87%。
- Abstract:
- Taking two-year-old seedlings of Fontanesia fortunei Carr.as test materials,the effects of physiological indicators changes in the blades of were studied under the conditions of artificial simulated continuous water-logging stress were studied.The results showed that the content of chlorophyll (a+b) and a/b ratio of the flooded group compared with the control group had the same variation trend，and the difference were not significant.By the end of water-logging stress the ratio of chlorophyll a/b were just above the control group，and the content of chlorophyll (a+b) were all under the control group.The contents of soluble sugar and MDA had the same variation trend，first increased then decreased.The two contents turned to the peak at 21 d，and turned back to the control level by the end of water-logging stress.The content of soluble protein were opposite to MDA trend during the early stage of water-logging stress，but the two had the same variation trend at the later stage，and dropped to 68% of control group finally.The content of proline compared with the control were accumulated most of the time.It had the same variation trend with MDA at the later stage of water-logging stress，and dropped to 87% of control by the end.By comprehensive analysis of the measured index and indicated that Fontanesia fortunei Carr.had definite tolerance to the water-logging stress.
