Fluoride remediation using floating macrophytes [2014]

Mondal, Naba Kumar; Bhaumik, Ria; Dey, Uttiya; Pal, Kartick Chandra; Das, Chittaranjan; Maitra, Anindita; Datta, Jayanta Kumar

Abstract:

Six aquatic macrophytes, such as Pistia stratiotes, Ceratophyllum demersum, Nymphoides indica, Lemna major, Azolla pinnata,and Eichhornia crassipes were considered for remove fluoride from aqueous solution. Five different concentrations (10, 30, 50, and 100 ppm) of fluoride solution were taken in 1 L plastic container. Fixed weight (20 g) of macrophytes along with 500 ml fluoride solution was ...

Effects of ultraviolet radiation on pigmentation and malondialdehyde content of three aquatic macrophytes [2014]

Chakraborty, Deep; Dey, Uttiya; Medda, Shreya; Datta, Jayanta Kumar; Roy, Tapas; Mondal, Naba Kumar

Abstract:

A study has been done in order to evaluate the ill effects of UV-A,UV-B and UV-C on pigmentation and malondialdehyde content of floating macrophytes (Lemna sp., Pistia sp. and Eichhornia sp.) in one, three, and five days interval. Study results revealed that all types of ultraviolet light (UV-A, UV-B, and UV-C) did not produce same extent of ill effects on the studied macrophytes. Pistia sp. a ...

Abstract:

The aim of this study was to determine the effectiveness of different solvents in extracting phenolic compounds and the evaluation of antioxidant capacity in apple (Malus domestica Borkh) and strawberry (Fragaria ananassa Duch). The values of phenolic compounds and antioxidant capacity found in the literature show a large discrepancy, even when it comes to the same species, or even the same cu ...

Impacts of vehicle exhaust black soot on germination of gram seed (Cicer arietinum L.) [2014]

Mondal, Naba Kumar; Panja, Debopriya; Das, Chittaranjan; Dey, Uttiya; Das, Kousik

Abstract:

An investigation was initiated to examine the effects of carbon soot collected from exhaust tube of 15 years old petrol and diesel operated vehicles on gram seed germination and biochemical changes of seedling. In view of the widespread cultivation of gram seed in India and long-term impact of black carbon is the warming of the atmosphere as per the recommendation of IPCC (2007). Black soot we ...

Differential susceptibility and resistance to glyphosate in annual ryegrass and wavy-leaved fleabane [2014]

Costa, Flávia Regina Da; Ansolin, Humberto Henrique; Carvalho, Leonardo Bianco De

Abstract:

Annual ryegrass (Lolium multiflorum) and wavy-leaved fleabane (Conyza bonariensis) were tested, aiming to investigate the dose-response of biotypes of both species to glyphosate. Glyphosate herbicide at doses varying from 0 up to 1.440 g e.a. ha-1 was sprayed onto annual ryegrass plants showed four leaves and wavy-leaved fleabane showed three pair of leaves. The fresh weight of shoot was obtai ...

Abstract:

Popularly known as coffee senna, Senna occidentalis (L.) Link (synonym: Cassia occidentalis L.) is a ubiquitous plant appreciated by many tropical communities, especially as a herbal medicine. It has been widely used for centuries, principally for the treatment of weakness, constipation, liver disorders and skin infections. Due to its poisonous potential to grazing anima ls, coffee senna is in ...

Abstract:

Field experiments were conducted with mung bean (Vigna radiata L. Wilczek) consecutively for three years (2009, 2010, and 2011) in the Crop Research and Seed Multiplication Farm, Burdwan University, West Bengal, India. In the first two years, varietals screening of mung bean under recommended dose of chemical fertilizer (20:40:20) were performed with five varieties with a local variety of mung ...

The intensity of non-target site mechanisms influences the level of resistance of sourgrass to glyphosate [2014]

Costa, Flávia Regina Da; Carvalho, Leonardo Bianco De; Cruz-Hipolito, Hugo Enrique; Alves, Pedro Luis Aguiar; De Prado, Rafael

Abstract:

Non-target site mechanisms are involved in the resistance of sourgrass (Digitaria insularis) to glyphosate. Studies on the 14C-glyphosate absorption and translocation as well as the detection of glyphosate and its metabolites in sourgrass plants were carried out under controlled conditions to investigate if the differential response of resistant sourgrass biotypes (R1 and R2) is derived from t ...

Abstract:

The trial was a split plot experiment based on randomized complete block design (RCBD) with four replications in Abadeh, Fars, Iran, during 2010-2011 growing seasons. The treatments were consisted of three levels of nitrogen (200, 300, and 400 kg ha-1) and four herbicide application levels (53, 68, 83, and 97 g ha-1). Interaction effects of N fertilizer×herbicide levels on number spike per m2, ...

Genotoxic effect of ethephon on the root meristems of Allium cepa L. [2014]

Priya, Joyce Sudandara; Purushothaman, Preethi; Hannah, Cordilea; Matthew, Sarah; Thomas, Sowmya

Abstract:

Genotoxic effect of ethephon [(2-chloroethyl) phosphonic acid], a PGR that has replaced calcium carbide as an agent for fruit ripening, was studied by using a root chromosome assay. Onion root meristems were cultured and analyzed after exposure with ethephon at concentrations of 200 ppm and 500 ppm for 2, 24, and 48 h. There was a time dependent decrease and an immediate toxic effect on dividi ...
