摘要: 陌上菅脱离水淹后随时间推移对叶的部分生理指标和地上部分营养成分进行测定并与对照进行比较研究,探讨了没顶水淹后陌上菅的恢复状况。结果表明,1)叶的MDA、可溶性糖和脯氨酸的含量在恢复的前4个阶段均显著高于对照,并随着时间的推移呈下降趋势,约1个月后恢复到对照水平。2)叶的叶绿素含量在整个恢复过程中与对照组相比均有显著性降低,但是随着时间推移呈逐渐上升的趋势。3)粗纤维含量、SOD和POD酶活性在整个恢复过程中与各自的对照相比均无显著性差异。4)粗脂肪和粗蛋白含量在整个恢复过程中随时间推移均呈上升趋势,但仍然显著低于各自的对照。5)地上部分的含水量在恢复的前4个阶段显著低于对照,但随着时间推移呈逐渐上升趋势,约40 d后恢复到对照水平。研究结果表明水淹后陌上菅具有一定的恢复能力。

Abstract: Some leaf physiological indexes and above-ground nutrition of Carex thunbergii were compared with the CK after prolonged waterlogging and the restoration situation is discussed. 1) The content of MDA, soluble sugar and proline in leaves were considerably higher than in the CK during the first four phases of restoration but significantly decreased with time and returned to the level of the CK about one month later. 2) The chlorophyll content in leaves was significantly lower than in the CK during the whole restoration phase, but increased with prolonged time. 3) The crude fibre content, SOD, and POD activity did not differ significantly from the CK during the whole restoration process. 4) The crude fat and crude protein contents increased with prolonged time in the whole restoration phase, but had decreased significantly compared with each CK. 5) The above-ground water contents were considerably lower than in the CK during the first four phases of restoration, but decreased with prolonged time, and were restored to the level of the CK about forty days later. This indicates that C. thunbergii has some restoration ability after waterlogging.
