Allelopathy as a mechanism for the invasion of Typha angustifolia

open access: yesPlant Ecology, 2009
The direct competitive effects of exotic plants on natives are among the leading causes of plant extinctions worldwide. Allelopathy, one type of direct plant competition, has received relatively little research, particularly in aquatic and wetland systems, even though allelopathy can be a potent mechanism through which plant communities are structured.

Long-term competitive displacement of Typha latifolia by Typha angustifolia in a eutrophic lake

open access: yesOecologia, 1993
This study follows the outcome of long-term competition between a broad-leaved and a narrowleaved Typha species, T. latifolia and T. angustifolia respectively, in a eutrophic lake. The lake was bordered by a zone of T. latifolia, at one location interrupted by a T. angustifolia stand. Distributional changes of the T. angustifolia stand and the adjacent

Growth strategy of an emergent macrophyte, Typha orientalis Presl, in comparison with Typha latifolia L. and Typha angustifolia L.

Limnology, 2006
The growth strategy of an emergent plant, Typha orientalis Presl, was examined in experimental ponds in comparison with two other Typha species distributed in Japan, Typha latifolia L. and Typha angustifolia L. T. orientalis showed the greatest ability of vegetative reproduction at the expense of growth in height. T.

Thermogravimetric study on typha (Typha angustifolia L.)

Journal of Thermal Analysis, 1989
Thermogravimetric analysis, was employed to study the thermal behaviour of typha, a naturally growing plant in the marshes of the south of Iraq, and its main components, holocellulose, hemicellulose and cellulose. The overall TG signal of typha appeared as the sum of those of hemicellulose and cellulose.

Lignified and nonlignified fiber cables in the lacunae of Typha angustifolia

Protoplasma, 2015
The leaves of Typha are noteworthy in terms of their mechanical properties. We determined the mechanical properties of the fiber cables within the leaf. We found that in vegetative plants, the lignified fiber cables isolated from the leaf sheath and nonlignified fiber cables isolated from the leaf blade of Typha angustifolia differ in their diameter ...

The potential for hybridization between Typha angustifolia and Typha latifolia in a constructed wetland

Aquatic Botany, 2004
Abstract Three Typha taxa are recognized in the central USA: native Typha latifolia (broad-leaved cattail), the invasive Typha angustifolia (narrow-leaved cattail), and a hybrid between the two species, Typha × glauca. Previous authors have suggested that interspecific hybridization is common in cattails.
