Morphological and physiological responses of lowland purple nutsedge (Cyperus rotundus L.) to flooding
BACKGROUND AND AIMS Purple nutsedge (Cyperus rotundus L.) is a major weed of upland crops and vegetables. Recently, a flood-tolerant ecotype evolved as a serious weed in lowland rice. This study attempted to establish the putative growth and physiological features that led to this shift in adaptation. METHODOLOGY Tubers of upland C. rotundus (ULCR) and lowland C. rotundus (LLCR) ecotypes were...
متن کاملSOIL ATTRIBUTES AND THE EFFICIENCY OF SULFENTRAZONE ON CONTROL OF PURPLE NUTSEDGE (Cyperus rotundus L.)
In the soil, herbicides are submitted to absorption, leaching and degradation by physical, chemical and biological processes or absorbed by plants. All these processes are dependent on soil class and weather conditions and affect the product efficiency on weed control. The objective of this work was to investigate the influence of soil attributes on sulfentrazone efficiency for controlling purp...
متن کاملeffect of soil solarization on the control of different purple nutsedge (cyperus rotundus l.) ecotypes
employment of solarization using the polyethylene mulch can be effective as a non-chemical approach for some control noxious weed management such as purple nutsedge (cyperus rotundus). in order to determine the effect of different levels of polyethylene mulches including one- layer clear polyethylene film, two- layer clear polyethylene film, one- layer black polyethylene film and two- layer bla...

متن کاملEffects of elevated atmospheric CO2 on invasive plants: comparison of purple and yellow nutsedge (Cyperus rotundus L. and C. esculentus L.).
The rise in atmospheric CO(2) concentration coupled with its direct, often positive, effect on the growth of plants raises the question of the response of invasive plants to elevated atmospheric CO(2) levels. Response of two invasive weeds [purple nutsedge (Cyperus rotundus L.) and yellow nutsedge (Cyperus esculentus L.)] to CO(2) enrichment was tested. Plants were exposed to ambient (375 micro...
