摘要

大型植物在水生生态系统的功能中起着重要的作用。它们的活动包括在生理和解剖水平上对各种污染物的作用的变化。本研究旨在揭示不同浓度硝态氮和水杨酸对小叶蝉根通气组织形成的影响。结果表明，红叶对硝态氮的抗性是通过根系气孔形成的再分配介导的。水杨酸的作用使两种不定根中硝态氮的影响减小。土生根与水生根的气组织形成特征不同。

The effect of nitrate nitrogen and salicylic acid on aerenchyma formation in Typha angustifolia grown in mesocosms

Macrophytes play a significant role in the functioning of hydroecosystems. Their activities include changes at the physiological and anatomical levels toward the action of various pollutants. This study was intended to reveal some features in aerenchyma formation in roots of Typha angustifolia exposed to various concentrations of nitrate nitrogen and salicylic acid. It was found that the resistance of T. angustifolia to nitrate nitrogen is mediated by redistribution of aerenchyma formation in the root system. The action of salicylic acids results in decreasing influence of nitrate nitrogen in two types of adventitious roots. Features of aeren- chyma formation in the soilborne roots and aquatic ones were different.

期刊介绍： Plant Root publishes original papers, either theoretical or experimental, that provide novel insights into plant roots. The Journal’s subjects include, but are not restricted to, anatomy and morphology, cellular and molecular biology, biochemistry, physiology, interactions with soil, mineral nutrients, water, symbionts and pathogens, food culture, together with ecological, genetic and methodological aspects related to plant roots and rhizosphere. Work at any scale, from the molecular to the community level, is welcomed.
