Benthic Barriers

An experiment was initiated to study the effects of rubber benthic barriers vs. aggressive cutting on the invasive aquatic emergent plant, yellow flag iris. Treatments were compared against a control at two locations within British Columbia, Canada (Vaseux Lake and Dutch Lake). Yellow flag iris response was significantly different between the two sites, but biologically the results were identical: the benthic barrier killed yellow flag iris rhizomes within 70 d of treatment. Over the extent of the research, at Vaseux Lake the effect of aggressive cutting was no different from the control, while aggressive cutting was statistically no different than the benthic barrier at Dutch Lake. Vegetation regrowth approximately 200 d after the benthic barriers were removed was not detected at either location. These results indicate that rubber benthic barriers may be an effective treatment for yellow flag iris and maybe suitable for other, similar species.

Abstract Invasions of Iris pseudacorus L. (yellow flag iris) into wetland environments can result in changes to the functioning of the ecosystem. Field-based and greenhouse studies were initiated to study the effect of water depth on regrowth rates of cut stems of yellow flag iris. The field-based experiment occurred at 41 independent populations around the perimeter of a single wetland. The greenhouse experiment was conducted to further study the effect of water depth and duration of submersion on rhizome mortality. In both studies, treatments were compared against controls. In the field-study, yellow flag iris regrowth was significantly affected by water, though there was no relationship between water depth and percent regrowth. In the greenhouse study, there was a significant positive relationship between duration of submersion and percent mortality of rhizomes. And, there was no relationship between water depth and percent mortality; indicating that as little as 5 cm of water is sufficient to kill yellow flag iris rhizomes, if the stems are cut to the base of the plant. Our results indicate a simple technique can control yellow flag iris within aquatic ecosystems without the need for chemicals or laborious hand removal.Nomenclature: yellow flag iris, Iris pseudacorus (L.)

Leaf senescence, the last stage of the developmental program of leaves, can be induced by both internal and external signals. Cold stress-induced leaf senescence is an efficient strategy to overcome winter temperatures. In this work, we studied leaf senescence in yellow flag (Iris pseudacorus L.) individuals growing in a natural wetland, not only considering its relationship with external and internal cues, but also the plant developmental program, and the biological significance of rhizomes, storage organs that remain viable through winter. Total chlorophyll contents and the maximum efficiency of PSII (Fv/Fm ratio) decreased in senescing leaves, which was associated with a sharp increase in abscisic acid (ABA) contents. Furthermore, total cytokinin and 2-isopentenyladenine contents decreased in December compared to November, as plants became more stressed due to a decline in air temperatures. ABA increases in senescing leaves increased in parallel to reductions in violaxanthin. Rhizomes also accumulated large amounts of ABA during winter, while roots did not, and neither roots nor rhizomes accumulated 9-cis-epoxycarotenoids, thus suggesting ABA, which might play a role in conferring cold tolerance to this subterranean organ, may result from phloem transport from senescing leaves. It is concluded that (i) leaf senescence is a highly regulated physiological process in yellow flag playing a key role in the modulation of the entire plant developmental program, and (ii) ABA plays a major role not only in the regulation of leaf senescence but also in the establishment of cold tolerance in rhizomes, two processes that appear to be intimately interconnected.
