Scirpus

The root cap has shifted gradually to an oblique position in tribe Dulichieae or to a sublateral position in a part of Scirpeae (the Scirpus clade).

Open circle = shallow areas with aquatic weeds (Scirpus californicus) and sandy bottom.

Considering this information and relating it to the EDXRF methodology developed in the present work, the concentration factors of Tessaria absinthioides, Typha angustifolia y Cyperaceae Scirpus were determined (Figure 5).

The structural demography and growth patterns of Scirpus grossus l.

It is about 8 Poaceae which we quote some species frequently ingested: Hordeum murinum and Poa annua, 2 Cyperacees Scirpus sp.

Approximately 50% of the 26.1 ha making up the Pintail Lakes section contained emergent marsh habitat dominated by cattail and bulrush (Scirpus species) due to varying amounts of rainfall in the region and differing management practices.

The plant species included bulrush (Scirpus californicus), softrush (Juncus effusus), water hyacinth (Eichhornia crassipes), duckweed (Lemna minor), pickerelweed (Pontederia), duckpotato (Sagittaria lancifolia), native canna (Canna spp.), buttonbush (Cephalanthus occidentalis), cutgrass (Leersia oryzoides), and native lotus (Nelumbo lutea).

Today Sweetgrass basket making involves four woven ingredients, including bulrush (Scirpus lacustris), long leaf pine needles (pinus palustris), sweetgrass (muhlenbergia), sewn with strips of palmetto leaf (Sabal palmetto).

Los resultados de la investigacion demostraron que la introduccion de tecnicas de surcos y hoyos posibilita mejorar el estado ecologico del pastizal de condicion muy pobre con menor uso de tiempo y recursos; asi lo sustenta la recuperacion de la especie vegetal Scirpus rigidus (planta nativa indicadora de pulsos de humedad del suelo), e incremento del rendimiento de biomasa y mantillo del area experimental dominado por la Calamagrostis macrophylla.

Overall, depending on the herbicide type, mixing 50% RR of herbicides with 500A- of RV or WV dilutions can effectively control the weeds in paddy rice such as Echinochloa crusgalli, Monochoria vaginalis and Scirpus juncoides without suppressing the growth, and yield of rice with acceptable soil impacts that promotes environment health.
