Multivariate analysis through Two Way Indicator Species Analysis (TWINSPAN) was conducted to study the phytosociological attributes of weeds of some selected crop fields of chickpea, mustard and wheat of Tehsil Isa Khel, District Mianwali, Punjab. Forty one (41) weed species were collected from the study area belonging to twenty one (21) different families. Twenty four weed species found in chickpea, twenty five in mustard and twenty nine in wheat crop fields. Sixteen weed species were common in three crops. Family Poaceae and Astraceae had maximum weed species i.e. 7 and 6 species respectively followed by Euphorbiaceae, Fabaceae, Chenopodiaceae, Papaveraceae, Zygophyllaceae and so on. Asphodelus tenuifolius, Medicago monantha and Carthamus oxycantha are frequently occurring weeds relative to others. Two-Way Indicator Species Analysis (TWINSPAN) was performed on the percentage cover basis which divided the weed species into groups, sub groups, associations and sub associations.

This research was made for the comparison of the effects of purple nutsedge allelopathy and other methods on the weed management in barely at Students’ Experimental Farm, Department of Agronomy, Sindh Agriculture University, Tandojam for weed as well as barely parameters having eight treatments with three replications. The data revealed that maximum weed number (45.6 m-2), weed fresh weight (20.6 g m-2), weed dry weight (6.3 g m-2) was observed under T1= No weeding (control). However, the maximum weed control (91.3%) was recorded under T7= Puma super 75 EW at 0.625 L ha-1, 50 reduced (30 DAS) + Purple nutsedge water extract at 15 L ha-1 (45 DAS). The barley crop results revealed that maximum tillers (355.6 m-2), plant height (106.3 cm), spike length (11.5 cm), grains spike-2 (47.3), seed index (51 g), biological yield (11737 kg ha-1), grain yield (4493 kg ha-1) and harvest index (41.9%) was recorded under T7= Puma super 75 EW at 0.625 L ha-1 50 % reduced (30 DAS) + Purple nutsedge water extract at 15 L ha-1 (45 DAS). Hence, current results manifested that proper application of puma super 75 EW at 0.625 L ha-1 50 % reduced (30 DAS) + Purple nutsedge water extract at 15 L ha-1 (50 DAS) produce maximum growth and yield parameters of barley crop. So, it was suggested that application of puma super 75 EW at 0.625 L ha-1, 50 % reduced (30 DAS) + Purple nutsedge water extract at 15 L ha-1 (45 DAS) apply for getting higher yield (4493 kg ha-1) of barley crop. It was finalized that this study will be very fruitful for the future progress of barley production.
本研究在信德省农业大学农学系坦多贾姆学生实验农场，采用8个处理，3个重复，比较紫栗草化感作用与其他方法对作物杂草管理的效果。结果表明:T1=不除草(对照)处理下，杂草数量(45.6 m-2)、鲜重(20.6 g m-2)、干重(6.3 g m-2)最大;而T7= Puma super 75 EW (0.625 L ha-1)， 50还原剂(30 DAS) +紫苣苔水提物(15 L ha-1) (45 DAS)处理的防杂草效果最好，达到91.3%。结果表明，在T7= 0.625 L ha-1 50%减量(30 DAS) + 15 L ha-1紫苣苔水提物(45 DAS)处理下，大麦的最大分蘖(355.6 m-2)、株高(106.3 cm)、穗长(11.5 cm)、穗数(47.3)、种子指数(51 g)、生物产量(11737 kg ha-1)、籽粒产量(4493 kg ha-1)和收获指数(41.9%)均达到最高。因此，目前的研究结果表明，适当施用0.625 L ha-1的puma super 75 EW降低50% (30 DAS) + 15 L ha-1 (50 DAS)的紫藜水提物可以获得最大的大麦作物生长和产量参数。因此，建议采用puma super 75 EW用量为0.625 L ha-1，减量50% (30 DAS) +紫色豆蔻水浸液用量为15 L ha-1 (45 DAS)，可获得较高的大麦产量(4493 kg ha-1)。本研究对今后大麦生产的发展具有重要的指导意义。

Red sprangletop (Leptochloa chinensis L.) is a problematic weed of aerobic rice (Oryza sativa L.) that greatly reduces in yield. The laboratory studies were undertaken to confirm allelopathicity of its plant leachates and soil-decomposition plant residues towards emergence and seedling growth of rice. In first experiment, aqueous extracts from various plant parts of red sprangletop (stem, root, leaves, flower and entire plant) at their 5% (w/v) concentration were applied to germinating rice seeds. In second experiment, soil-decomposed red sprangletop plant residues of variable concentrations (2, 4 and 6% w/w) were used as germination media for rice. Among plant parts, red sprangletop leaves showed maximum allelopathic effect by fully inhibiting the germination of rice while its stem could be positioned at second situation as it caused 60, 73, 84.13 and 86 % reductions in germination percentage, germination index, seedling length and seedling dry biomass of rice as compared with control, respectively. This treatment also resulted in maximum delays in mean germination time (up to 4.80 days) and days taken to 50% germination (up to 4.40 days) of rice. The highest concentrated (6%) soil-decomposed plant residue of red sprangletop significantly diminished the germination percentage, germination index, seedling length and seedling vigor index that were 35.13, 23.26 and 41.61% lower than control. It very well may be presumed that liquid concentrates of leave and stem soil-decomposed plant residues of 6% concentration had different kind of allelochemicals that inhibited the germination, seedling growth and development of rice.

The present study was conducted to assess the allelopathic potential of Zizypusmauritiana against some crop species. Plant materials of Z.mauritiana were collected from Ahmad Abad District Karak and dried at room temperature (25-30˚C). Allelopathic studies conducted by using aqueous extracts from various parts including mature leaves, bark, fruit rain water and mulching in various experiments invariably retarded the germination, plumule, radical growth, fresh and dry weight of Trictium aestivm, Zea mays, and Cicer arietinum., used as a test species. The aqueous extracts obtained after 48 h were more inhibitory than 24h. Leaves were more toxic than fruit and bark. Rain water and mulching experiments also proved to be inhibitory. It is suggested that the various assayed parts of Z.muritianahave strong allelopathic potential at least against the tested species. Further investigation is required to see its allelopathic behavior under field condition against its associated species and to identify the toxic principle.
本文研究了毛里毛提紫霉(Zizypusmauritiana)对几种作物的化感作用。毛里沙娜(Z.mauritiana)植物材料采集自Ahmad Abad District Karak，室温(25-30℃)干燥。利用成熟叶片、树皮、果实雨水和地膜等不同部位的水提取物进行化感作用研究，在不同的实验中，都不可避免地延缓了Trictium aestivm、Zea mays和Cicer arietinum的发芽、胚芽、根茎生长、鲜重和干重。，用作试验种。48h后得到的水提物比24h后得到的水提物具有更强的抑制作用。树叶比果实和树皮毒性更大。雨水和地膜试验也证明有抑制作用。结果表明，各被测部位至少对被试种具有较强的化感作用。需要进一步研究其在野外条件下对其伴生物种的化感作用，并确定其毒性原理。

Further investigation is required to see its allelopathic behavior under field condition against its associated species and to identify the toxic principle.","PeriodicalId":17469,"journal":{"name":"JOURNAL OF WEED SCIENCE RESEARCH","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78551180","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Locally famous Karhee or Berre (Sorbaria tomentosa) exhibits medicinal value is large woody shrub indigenous to Pakistan. The present study examined the cytotoxic activities of S. tomentosa using methanolic extracts and fractions (n-hexane, dichloromethane, ethyl acetate and water) against three cáncer cell lines (lung A-549, hepatocellular HepG2and urinary bladder EI-138). Cytotoxic assays were carried out with five different concentrations (0.05, 0.01, 0.05, 0.1 and 0.5 mg/mL) of methanolic extract and its sub fraction through MTT assay. Results revealed n-hexane and ethyl acetate fraction being the most potent against all test cancer cell lines with higher IC50 values. Both fractions also exhibited the maximum reduction in the cell viability in dose dependent manner. Preliminary results suggest the promising anticancer potential of n-hexane and ethyl acetate S. tomentosa against lung A-549, hepatocellular HepG2and urinary bladder EI-138 cell lines. Further studies are required to know the mechanism(s) involved in the cell death.

Abstract Two separate experiments were conducted to examine the effect of various water regimes and herbicides on re-sprouting-ability of common reed rhizome fragments. Each experiment was laid-out in completely randomized design (CRD) having water levels and herbicides as treatments, replicated thrice. Five fragments of fresh rhizomes with active buds were placed in the soil in each pot for investigating the effect of various water regimes on re-sprouting of common reed. Sprouting were examined up to two months. While in the 2nd experiment post emergence herbicides were applied to the re-sprouts to check the efficacy of various herbicides against common reed management. Various water regimes affected the re-sprouting ability of common reed rhizomes. The lowest sprouting (6.66%) were noted for T8 (control) where no water was applied except at the time of placing the rhizomes in the pots, while maximum (96.66%) sprouting observed within (T3) water was applied from 5th to 7th weeks (5 times). While in the 2nd experiment herbicides significantly affected the re-sprouting ability, growth and biomass production of common reed and minimum re-sprouting and shoot biomass (3.33% and 6.00 g), respectively, were noted for fenoxaprop-p-ethyl as compared to control treatment (90.00% and 38.67 g) where no herbicide had been applied. Therefore it is concluded from the results that on either side from water regime T5 the re-sprouting ability decreases and buds mortality increases, which clearly indicates that common reed needs slightly moist soil to start the re-sprouting and do not need standing water during that period, while after re-sprouting it do needs water i.e. from 3rd weed onwards and dry conditions afterwards (T6-T8) cannot be tolerated. Therefore flooding common reed after cutting [1]for three weeks of draining and keeping them dry for 8 weeks can be used as cultural control method for common reed management, while in case of herbicides fenoxaprop-p-ethyl gives desirable results to control the common reed and to stop further infestation.
