以滴水观音（Alocasia macrorrhiza）为供试材料，研究了短期干湿交替胁迫对滴水观音的叶片抗氧化系统、丙二醛以及脯氨酸含量的影响。结果显示，短期干旱胁迫下，滴水观音可增强 POD、 CAT 酶系活性，提高 Pro与 MDA 含量以抵御干旱胁迫的影响；复水后，植株抗氧化系统、丙二醛以及脯氨酸含量发生明显变化：与对照相比，短期深水位淹水胁迫会提高植株抗氧化系统酶活性，增加植株叶片 Pro 与 MDA 含量，并随淹水水位增加胁迫作用越明显。试验结果进一步显示，短期干旱胁迫后，及时补充适宜水分（1／4淹水或仅淹没根部）可促使植株恢复到正常生长水平。

Alocasia macrorrhiza was used to study the effect of short time wet -dry alternation on its antioxidant enzyme sys -tem ( SOD, POD, CAT), malondialdehyde ( MDA) and proline ( Pro).The results showed that under short time drought stress, POD and CAT enzyme activities enhanced , Pro and MDA contents to resist the influence of drought stress . After rehydration, the antioxidant enzyme system, Pro and MDA contents changed significantly : compared with control, short time deep water flooding stress could enhance POD and CAT enzyme activities , increase leaves Pro and MDA con-tents, and the stress effect was more obvious with water level increasing .The results also showed that adding suitable water (1 /4 drowned or only root drowned ) could spur plant return to normal growth after short time drought stress .
