摘要/Abstract

摘要： 为了研究园林管理中水分对蕨类植物的影响,以人工控水的方式模拟干旱条件,研究干旱对铁线蕨、毛蕨、肾蕨叶片相对含水量、叶绿素含量、蒸腾速率、丙二醛含量以及可溶性糖含量五个生理指标的影响。研究结果表明：三种蕨类植物在干旱条件下,随着天数的增加,叶片相对含水量、叶绿素含量、蒸腾速率降低,丙二醛含量和可溶性糖含量呈上升趋势。在相同的状态及方法下,肾蕨抗旱能力较强,三种蕨类植物抗旱能力的强弱依次为：肾蕨>毛蕨>铁线蕨。

Abstract: To understand the effect of water on ferns in garden management, artificial water control was used to produce arid environment for the study of leaf relative water content, chlorophyll content, transpiration rate, malondialdehyde content and soluble sugar content changes in physiological indicators. Result: Under the drought conditions of these three ferns, the relative water content, chlorophyll content and transpiration rate decreased and the malondialdehyde content and soluble sugar content increased with the increase of days. It was found that, under the same condition and method, the ability of drought-resistance of kidney ferns was strong. The strength of the three kinds of ferns in terms of drought-resistance ability decreased in the following order: Nephrolepis auriculata (L.) Trimen > Cyclosorus interruptus (Willd.) H. Ito > Adianturn capillarus-veneris.

Key words: Drought resistence, Adianturn capillarus-veneris, Cyclosorus interruptus (Willd.) H. Ito, Nephrolepis auriculata (L.) Trimen, physiological biochemistry
