Allelopathic suppression of wheat and mustard byRumex dentatus ssp.klotzschianus

Abstract

Laboratory studies were conducted to see the ailelopathic suppression of wheat and mustard by Rumex dentatus ssp. klotzschianus (Meissn) Rech. It was observed that aqueous extracts, rain leachates and litter from dried and fresh shoot and roots invariably inhibited the germination and seedling growth of both the crop species. Soil collected from beneath Rumex dentatus also proved harmful for the germination and seedling growth. It is suggested that Rumex dentatus ssp. klotz,~chianus exhibits allelopathy against wheat and mustard.

Phytochemical screening, antimicrobial and antioxidant efficacy of different extracts of Rumex dentatus L. – A locally used medicinal herb of Kashmir Himalaya

“…Ethno-botanical information revealed that the plant selected in this study is traditionally used for various medicinal purposes [20][21][22][23] . The antimicrobial activityof different plant extracts against the various clinical strains of bacteria and fungi supported the scientific validity of the plant being used traditionally as a medicine and vegetable.…”

“…When analysed against fungi, it was found effective only against A. flavus and P. dimorphosporum. Among all these extracts, butanol showed the highest antibacterial efficacy against K. pneumoniae with IZD of 20 mm, whereas the lowest efficacy against S. aureus (8 mm IZD) compared to the positive control (gentamycin 32-38 mm). S. typhimurium showed complete resistance against all concentrations of this extract.…”

Isolation, Identification, Antibacterial activity and Docking of Fatty acid and Fatty alcohol from Rumex dentatus Leaf Extract

“…Fraction M4 was further eluted using gradient petroleum ether/ benzene (3/7 7/3 v/v) by glass column chromatography to yield four subfractions M41-M44. Subfraction M42 was purified by CC using silica gel using gradient petroleum ether/C6H6 (5/5 v/v) to yield a white colour powder of compound (1), and M43 was purified using gradient hexane/EtOAc (95/5 v/v) to give white powder of compound (2). The compound (1) and 2was further characterized by various spectroscopic methods such as 1H-NMR, 13…”

“…It is a widely distributed many temperate and tropical countries such as India, Afghanistan, Pakistan, East Asia and is used in the Mediterranean diet 1 . Rumex dentatus shows allelopathic activity against wheat and mustard 2 . Mostly, allelochemicals of plants are phenolic compounds which increase the generation of reactive oxygen species (ROS) and biological stress 3 .…”

Insecticidal Effects of Two Plant Extracts of (Bidens pilosa and Rumex dentatus) and Neem Oil Against Certain Stored Grains Insects.

“…In addition, B. pilosa has a long tradition as folk medicine worldwide to treat various ailments and it is known to possess insecticidal properties against tea pests (Mamun and Ahmed, 2011), and to control the bruchid pests (A. obtectus and Zabrotes subfasciatus) of common beans in storage . The toothed dock, Rumex dentatus L. is a plant of the Polygonaceae family that is widely distributed in many countries including Egypt and possesses antifungal, antibacterial, insecticidal and allelopathic activities (Hussain et al, 1997;Umer et al, 2010).…”
