Abstract:
Nagarmotha (Cyperus rotundus) is found throughout India. Its genus name Cyperus is derived from Cypeiros, an ancient Greek name and rotundus from a Latin word for round and refers to the tuber. It is locally known as “Mutha”. The plant is a widely used traditional medicinal herb in India, China, Japan, Korea, Combodia, Nigeria, and Bangladesh. The plant produces rhizomes, tubers, basal bulbs and fibrous roots below ground and rosettes of leaves, scapes and umbels above ground. The rhizomes of nut grass is widely utilized in ancient medication round the world to treat various diseases like constipation, dysentery, abdominal distention, animal tissue stomach ache, chest pains, irregular catamenia, painful catamenia, skin diseases, staphylococcal infection infections, leprosy, sprains and bruises, and fever, analgesic, sedative, medication, anti malarial drug, abdomen disorders, and diarrhoea . Cyperus rotundus has the properties of antimicrobial activity, anti-lesion activity, analgesic activity, anti inflammatory activity, anti diarrhoeal activity, antipyretic activity, medication activity, anti-emetic activity, tranquilizing activity, anti urolithatic activity, antispatic activity, hypolipidaemic activity, wound healing activity, medication activity, inhibitor activity, metastatic tumor activity, antifungal activity, antidiabetic drug activity, anti-obesity activity, antiallergic activity, anti-blood platelet impact, opposing rheumy activity, anti malarial drug activity, gastroprotective activity, hepatoprotective activity, cytoprotective impact, hypotensive activity, ovicidal and larvicidal activity . The petroleum ether extract and essential oil of Cyperus rotundus possessed analgesic activity. Phenols and alkaloids are the active constituents of C. rotundus. Cyperus rotundus preparations (powder in fine suspension, aqueous and alcoholic extracts) exhibited a lipolytic action and mobilized fat from the adipose tissues and thus helping to reduce the obesity. Methanolic extract of the fresh aerial part of the Cyperus rotundus was fractionated by column chromatography method using petroleum ether, chloroform, ethyl acetate and methanol. The ethyl acetate fraction showed potent antibacterial activity compared to control and standard commercial antibiotic tetracycline. It is a widely used plant in traditional medicine around the world for treatment of various diseases. It is deemed with infinite medicinal properties authenticated by the scientific committee. The rhizomes of Cyperus rotundus are used as traditional folk medicine for the treatment of stomach and bowel disorders and inflammatory diseases in Asian countries. The use of the plant as an analgesic, anti-arthritic, antibacterial, anti-cancer, anticandida, anti-convulsant, anti-diabetic, anti-emetic, anti-histaminic, anti-inflammatory, anti-malarial, anti-obesity, anti-pyretic, anti-spastic, gastroprotective, hypotensive, sedative, and tranquilizing agent has been documented by various scientists. Ethnobotanical use of Cyperus rotundus showed that the rhizomes were used to treat aging, apoptosis, atherosclerosis, cancer, cystitis, epilepsy, genotoxicity, hirutism, nociception and prostatitis disorders. The tuber part of Cyperus rotundus is also used for the treatment of dysmenorrheal and menstrual irregularities from ancient times. The rhizome of Cyperus rotundus are α-cyperolone, β-cyperone, ρ-cymol, calcium, camphene, copaene, cyperene, cyperenone, cyperol, cyperolone, caryophyllene, cyperotundone, d-copadiene, d-epoxyguaiene, isocyperol, isokobusone, kobusone, limonene, linoleic-acid, linolenic-acid, mustakone, myristic acid, oleanolic acid, oleic acid, β-pinene, patchoulenone, rotundene, rotundenol, rotundone, α-rotunol, β-rotunol, β-selinene, selinatriene, sitosterol, stearic acid, sugeonol, and sugetriol. Phytochemical constituents of Cyperus rotundus revealed the presence of alkaloids, flavonoids, glycosides, phenols, tannins, steroids, starch and many novel sesquiterpenoids. Sesquiterpene hydrocarbons such as cypera-2,4 (15)-diene, isorotundene, norrotundene and the oxygenated compound cyperadione were isolated and identified.

Abstract:
Feeding between 0.00 and 54.55 percent of Cypenis bulbs in guinea fowl diets resulted in significantly (P<0.05) different body weight gain, feed intake, egg production and egg weight. Mean weekly body weight gain was significantly (P<0.05) higher in birds fed rations containing between 0 and 41% of Cyperus bulb than those on ration containing 54.55% of Cyperus bulb. Males on rations containing between 0 and 41% of Cyperus bulb had significantly (P<0.05) higher weight gains than their female counterparts fed the same rations. Feed intake decreased significantly (P<0.05) with increased inclusion of Cypenis bulb. Weekly feed intake was however significantly (P <0.05) lower in male birds on rations 1 and 2 than those on 3 and 4. The percentage of cocks in semen production ranged from 69.3 to 73.2% and was not significantly affected by ration. Egg weight and egg production became significantly lower (P<0.05) lowered as maize was replaced with Cyperus bulb though production on rations 1 and 2 were statistically similar. The differences in nutrient digestibility and nitrogen retention are probably responsible for the varying performances. The results indicate that except for semen production and feed intake in the male, the other parameters were adversely affected by Cyperus bulb inclusion

Abstract:
Background and aims – Molecular phylogenetic studies have provided a clearer understanding of the complex relationships within the family Cyperaceae. These studies have consistently shown that 12 allied genera are nested in the genus Cyperus. However, early Sanger sequencing-based phylogenies that included the two species of the small South American genus Androtrichum were inconclusive in placing this genus either as sister to Cyperus or as part of its early divergent lineages. A recent phylogenetic analysis however conclusively placed the two species of Androtrichum within the C3 Cyperus Grade. In this study, we investigate if the morphology and anatomy of Androtrichum species provide additional evidence for their placement in the genus Cyperus. In addition, we provide descriptions and distribution data for the species.Material and methods – Herbarium material from FLOR, FURB, GENT, ICN, and K has been studied. Samples of the culm and leaf were studied using histological methods. Taxonomic changes and typifications of names were performed according to the International Code of Nomenclature for algae, fungi, and plants. Key results – The morphology and the non-Kranz anatomy observed in the Androtrichum species confirm their placement among the other C3 Cyperus species. Androtrichum is combined into Cyperus. For one species, a combination in Cyperus is already available: Cyperus trigynus. For the other species, a new name in Cyperus is published: Cyperus byssaceus. Two typifications are established and morphological descriptions and distribution data are provided. Conclusion – By integrating recent molecular phylogenetic data with additional evidence from morphology and anatomy, Androtrichum is combined into Cyperus. As a result of this taxonomic change, a single monophyletic genus Cyperus is now recognised in the Cyperus Clade of tribe Cypereae.

Abstract:
Considering the problems of low soil fragmentation rates, high working resistance, and high energy consumption in the harvesting process of Cyperus esculentus in China, a method of Cyperus esculentus harvesting based on counter-rotation digging is proposed. The mechanism of interaction between the rotary tillage blade and Cyperus esculentus–soil is systematically investigated, and the vertical and horizontal disturbance performance of the positive and counter-rotating harvesting methods on soil and Cyperus esculentus is compared and analyzed. The results of the experiment showed that the intensity of soil and Cyperus esculentus disturbance by counter-rotation increased by 166.67% and 297.78%, respectively, and the effective disturbance time of soil and Cyperus esculentus increased by 133.33% compared to that of positive rotation. The working depth and rotation speed of the rotary tillage blade were the most significant for soil and Cyperus esculentus disturbance intensity. The working depth increased from 150 mm to 170 mm, and the soil disturbance intensity increased by 17.91% and 21.37% for positive and counter-rotating operation, respectively, and the rotation speed of the rotary tillage blade increased from 270 rpm to 330 rpm, and the soil disturbance intensity increased by 28.85% and 35.29%, respectively. Compared with the positive rotation operation, the Cyperus esculentus counter-rotation soil fragmentation rate increased by 4.09%, the Cyperus esculentus damage rate decreased by 10.69%, and the buried fruit rate decreased by 7.38%. This paper helps to understand the interaction mechanism between the rototiller and Cyperus esculentus–soil and lays a theoretical foundation for the subsequent design and optimization of the Cyperus esculentus digging device.

Abstract:
Alstonia scholaris contains flavonoids, tannins, triterpenoids, resins and alkaloids. Alkaloid compounds, tannins and flavonoids of plant origin can inhibit weed growth. Alkaloid compounds, tannins and flavonoids work by suppressing the hormone auxin and the hormone gibberelin so that weed growth is inhibited. This study aims to determine the potential of Alstonia scholaris leaves in inhibiting the growth of weed Cyperus rotundus. The inhibition of Cyperus rotundus growth can be seen from changes in leaf color/population phytotoxicity, number of leaves, and height of Cyperus rotundus. The research used Cyperus rotundus leaves which were mashed into flour and then extracted by macerating with alcohol 96% . The results of the extract of Cyperus rotundus leaf flour consisting of a concentration of 0 g/l (control), 25 g/l, 50 g/l, 75 g/l, and 100 g/l were applied to Cyperus rotundus. Pure extracts are given with different concentrations to determine the concentration that is effective in suppressing the growth of Cyperus rotundus. Vegetable herbicides of Cyperus rotundus leaves with a concentration of 50 g/l became the solution to control the enchanted grass weeds that are environmentally friendly without using synthetic herbicides. With the results of phytotoxicity P2= 40.00%, wet weight P2= 1.53 g, and dry weight P2= 0.91 g.

Abstract:
Quick emergence of Cyperus create competition in the crop production which reduces the crop yield. Nowadays, the more importance is given to sustainable agriculture. Application of allelochemicals can control the Cyperus sustainably. With this notion, field experiment was conducted at The Indian Agriculture College, Radhapuram during summer 2023 to evaluate utilization of Parthenium leaf extract (PLE) for the effective management of Purple nutsedge (Cyperus rotundus). The experiment was laid out in completely randomized block design (CRD) having three replications and seven treatments viz., PLE @ 10%, 11%, 12%, 13%, PLE @ 10% + Glyphosate @ 1.5%, Glyphosate @ 1.5% alone and Control. Application of PLE @ 11% on 3, 10 and 20 DAP, significantly reduces the Cyperus rotundus germination percentage, dry weight, Vigour Index, total Cyperus length, tuber weight, moisture content, chlorophyll content and also improved the Cyperus control efficiency due to the presence of allelochemicals.

Abstract:
The family Cyperaceae includes approximately 3000 species, of which about 220 species are identified as weeds (Table 1). Nearly 42% of these weeds are in the genusCyperus. An additional 43% are in three other genera,Eleocharis,Scirpus, andFimbristylis. The remaining 15% are found in six other genera,Scleria,Kyllinga,Rhynchospora,Bulbostylis,Fuira, andDichromena. Purple nutsedge (Cyperus rotundusL. # CYPRO) was identified as the world's worst weed based on the number of countries where it was reported as a serious, principal, or common weed. Competition with crops was the major factor in determining weediness. From the same report, yellow nutsedge (Cyperus esculentusL. # CYPES) ranked sixteenth. This contrasts with relative rankings of these two species in the United States where yellow nutsedge is more widespread than purple nutsedge.

Abstract:
Cyperus prophyllatus, an endangered new species of Cyperus (Cyperaceae) from an aquatic ecosystem of the Atlantic Forest, Espírito Santo State, southeastern Brazil, is described and illustrated. The spikelet morphology of Cyperus prophyllatus is unique among the c. 950 species of Cyperus in having both a conspicuous spikelet prophyll and a corky rachilla articulation, which remain persistent at the base of the spikelet after disarticulation.

Abstract:
Cyperus (Cyperus esculentus L.) is an edible perennial grass-like plant, which propagates exclusively with underground tubers. Its tubers are rich in starch (20–30%), fat (25–35%), sugar (10–20%), protein (10–15%) and dietary fiber (8–9%). In addition, the tubers also contain alkaloids, organic acids, vitamins (C and E), steroids, terpenoids and other active components. The contents of oleic acid and linoleic acid in Cyperus oil are very high, which have important medicinal value and health-promoting properties. Most of the extracts from the tubers, stems and leaves of Cyperus have allelopathic potential and antibacterial, antioxidant and insecticidal activities. In recent years, the planting area of Cyperus has increased significantly all over the world, especially in China and some other countries. This paper presents the current status of Cyperus and the recent trend in research in this area. Published reports on its nutritional contents, active ingredients, medicinal efficacy, antibacterial activity and allelopathic potential were also reviewed.

Abstract:
In order to investigate the ability of Cyperus alternifolius in restoring water with combined heavy metal pollution, water cultured experiment was utilized to study the accumulation and the tolerance mechanism of Cr (VI) and Ni in Cyperus alternifolius under the combined Cr (VI) and Ni exposure. The results showed that under Cr (VI) and Ni combined exposure, low concentration Ni improved the enrichment and translocation ability of Cyperus alternifolius for chromium, while high concentration Ni had opposite effects. The enrichment ability of Cyperus alternifolius for chromium was stronger than for Ni. With the increasing of Cr (VI) and Ni concentrations, fresh weight increment and chlorophyll content showed upward trend firstly and then downward, MDA content showed a rising trend and increased significantly. When Ni concentration was between 0~1mg·L-1, SOD and CAT activities of Cyperus alternifolius increased first and then decreased with increasing Cr (VI) concentration, and root activity increased continuously. When Ni concentration was between 10~20 mg·L-1, Cr (VI) and Ni interaction decreased SOD,CAT and root activity significantly. These results show that Cyperus alternifolius had tolerance and enrichment ability to Cr (VI) and Ni, and Cyperus alternifolius can be used to restore Cr (VI) polluted water and Cr (VI)-Ni combined polluted water under low Ni concentrations.

Abstract:
The sedge genera Alinula, Ascolepis, Kyllinga, Lipocarpha, Pycreus, Queenslandiella, Remirea, Sphaerocyperus and Volkiella (Cyperaceae) were recognised at generic level because they possess specialised inflorescence and/or flower characters. However, recent molecular phylogenetic analyses show that these genera are all nested in a paraphyletic Cyperus s.s. and therefore should be viewed as part of a broadly circumscribed genus Cyperus. For all species of Alinula and for the single species of Queenslandiella, Remirea and Sphaerocyperus, Cyperus names were already published by other authors. For the species of Lipocarpha and Volkiella, Cyperus names and a new sectional classification are published in a separate paper including a detailed molecular phylogenetic hypothesis for these taxa. Based on a study of herbarium specimens and literature, in this paper, twenty species of Ascolepis, seventeen species of Kyllinga, and six species of Pycreus, which do not yet have a validly published and legitimate name in Cyperus, are formally included into Cyperus as new combinations or new names. Notes on the synonymy of an African Pycreus species are also included.

Abstract:
Genetic diversity within and among populations of yellow nutsedge (Cyperus esculentusL. # CYPES) was analyzed to evaluate and quantify the genetic consequences of the reported predominance of asexually-produced tubers as colonizing agents. Ten populations were examined using starch gel electrophoresis for allozyme analysis. Four populations of purple nutsedge (Cyperus rotundusL. # CYPRO) were surveyed for comparison. Twelve loci were identified in yellow nutsedge among the eight enzyme systems examined; ten of these loci were found in purple nutsedge. Yellow nutsedge showed relatively low genetic diversity. Most of the genetic diversity occurred as differences among individuals within populations (Hs), compared to differences among populations (Dst) for the four variable loci identified in this species. Thus, most genetic distancesbetween its populations were small. Generally, only a few genotypes occurred within each population. Purple nutsedge was found to possess even lower within- and among-population gene and genotypic diversity. This study supports the view that tubers account for most of the establishment of new populations of both species.

Abstract:
Currently, the mechanized harvesting method of Cyperus esculentus is mainly based on rotary excavation, but there are problems such as high working resistance, high damage rate, and high buried fruit rate in the working process. This paper focuses on the analysis of the movement trajectory of the positive-rotating and counter-rotating Cyperus esculentus excavation device, establishes a agglomerate model of soil-Cyperus esculentus tuber-Cyperus esculentus root system-mechanism, and conducts discrete element simulation tests on Cyperus esculentus agglomerates under different soil layers. According to Expert test optimization, the optimal structural parameters of the counter-rotating blade are determined: the radius of gyration is 151 mm, the inclination angle of the cutting edge is 42.5°, and the working width is 318 mm. The comparative test of the positive-rotating rotary tillage method under the optimal structural parameters shows that the working resistance is reduced by 11.25%, and the torque of the tool shaft is reduced by 16.11%, which proves that the designed anti-rotation excavation structure has the effect of reducing resistance. To further test the harvesting performance of the Cyperus esculentus excavation device, field harvesting tests were conducted, and the results showed that the buried fruit rate of the counter-rotating excavation device was reduced by 11.6%, and the damage rate was reduced by 6.1% year-on-year. This study shows that the design of the counter-rotating excavation device can further improve the harvesting performance of Cyperus esculentus based on reduced resistance harvesting and meet the requirements of Cyperus esculentus harvesting.

Abstract:
To improve the drying efficiency, drying uniformity and germination rate after hot air drying of Cyperus esculentus seeds, this paper proposed a drying method that combines tempering and hot air drying. The drying curve of Cyperus esculentus was obtained by experiment. The influence of the drying method on the drying quality of Cyperus esculentus seeds and the trend of drying quality with the tempering process parameters (the tempering temperature, the moisture content of Cyperus esculentus at the beginning of tempering and the tempering duration) were analyzed by single-factor experiments. The regression models were established by star point design response surface methodology, and the relationships between the tempering process parameters and seed production quality indexes were analyzed. The results showed that the optimal combination of tempering process parameters was a tempering temperature of 24 °C, a moisture content of Cyperus esculentus at the beginning of tempering of 23%, and a tempering duration of 3 h. Under this combination, the tempering process increased the drying uniformity, germination rate and drying efficiency of Cyperus esculentus seeds by 21.122%, 4.205% and 22.832%, respectively. The error between the verification test value and the software optimization parameter value was acceptable. The study showed that the optimized tempering drying process significantly improved the drying quality of Cyperus esculentus seed production, and the results could provide a theoretical basis for production practices.

Abstract:
Cyperaceae are a plant family of grass-like monocots, comprising 5600 species with a cosmopolitan distribution in temperate and tropical regions. Phytochemically, Cyperus is one of the most promising health supplementing genera of the Cyperaceae family, housing ≈950 species, with Cyperus rotundus L. being the most reported species in pharmacological studies. The traditional uses of Cyperus spp. have been reported against various diseases, viz., gastrointestinal and respiratory affections, blood disorders, menstrual irregularities, and inflammatory diseases. Cyperus spp. are known to contain a plethora of bioactive compounds such as α-cyperone, α-corymbolol, α-pinene, caryophyllene oxide, cyperotundone, germacrene D, mustakone, and zierone, which impart pharmacological properties to its extract. Therefore, Cyperus sp. extracts were preclinically studied and reported to possess antioxidant, anti-inflammatory, antimicrobial, anticancer, neuroprotective, antidepressive, antiarthritic, antiobesity, vasodilator, spasmolytic, bronchodilator, and estrogenic biofunctionalities. Nonetheless, conclusive evidence is still sparse regarding its clinical applications on human diseases. Further studies focused on toxicity data and risk assessment are needed to elucidate its safe and effective application. Moreover, detailed structure-activity studies also need time to explore the candidature of Cyperus-derived phytochemicals as upcoming drugs in pharmaceuticals.

Abstract:
All species in the genus Cyperus (Cyperaceae) that occur in temperate eastern North America were assigned to either the C3or C4photosynthetic pathway using leaf anatomical characteristics and stable carbon isotope ratios. Of the 39 species in the study area, 32 had C4photosynthesis while 7 had C3. The numbers of C3, C4, and total Cyperus species were significantly and positively correlated with both summer precipitation and mean annual temperature. However, the proportional abundance of C4species within Cyperus was not significantly related to either climatic variable. The highest Cyperus diversity was found on the Atlantic Coastal Plain, a pattern that remained after climatic differences between regions were accounted for. All the C3species and the majority of the C4species were restricted to wetlands or damp soil habitats; 13 of the 32 C4species occurred in dry, sandy habitats. Given that the C3pathway is ancestral in the genus Cyperus, it appears that C4photosynthesis evolved in a wetland context for this genus. We suggest that the high nitrogen use efficiency associated with the C4pathway is largely responsible for the evolution and ecological success of C4Cyperus species in infertile, temperate wetlands.Key words: C3and C4photosynthetic pathways, Cyperus, Cyperaceae, eastern North America, stable carbon isotopes.

The study determined the effect of alcoholic extract of common purslane, Portulaca oleracea, Java grass, and Cyperus rotundus oil in controlling the two-spotted spider mite on okra plants. The results of laboratory experiments showed the efficiency of purslane alcoholic extract was highly toxic to adult mites, but its effect was limited on eggs. In contrast, Cyperus oil was highly effective against mite eggs and adults. Cyperus oil gave the highest mortality of 86.94%, with significant differences from the purslane extract, where 68.61% mortality was observed and differed significantly from the control treatment. An increase in mortality increased with concentration, and the highest mortality of 95.83% was achieved at 5%, compared to the mortality of 59.58% at 1% treatment. The ovicidal activity was significant after the C. rotundus oil treatment compared to the purslane extract application. Cyperus oil reduced egg hatching by 42.50%. However, purslane extract did not affect the hatching significantly (91.70% hatching) and was not significantly different from the control. In general, the hatching rate decreased with increasing concentration of Cyperus oil and was only 40% at the 5% treatment compared to 60 and 96.70% at 1% treatment and controls, respectively..
