The potential of an ornamental shrub Crown of thorns (Euphorbia milli) was evaluated for remediation of soil contaminated with Cr. The plant is one of the rare succulent ornamental shrubs with a slow to moderate growth rate and is capable of blooming almost year-round. The plant could tolerate well up to 75 mg of applied Cr and beyond that there was(More)
Phytoremediation of soils contaminated with heavy metals has received considerable attention in recent years. Because of the contamination of food and vegetable crops with heavy metals, greater emphasis has been given to the cultivation of floriculture plants for remediation of the contaminated soils. In the present experiment, the response of rose to soil(More)
To identify parameters that can be used for the analysis of natural variation in leaf senescence of wheat; and to understand the association between the onset and progression of leaf senescence with N uptake and root traits. Chlorophyll content and the proportion of yellow leaves were used as senescence indicators and their relation with other morphological(More)
Brassica genotypes representing four different species viz. B. nigra and B. campestris (both primary diploids), B. juncea and B. carinata (both allotetraploids) were examined for photosynthesis rate (Pn), ribulose-1,5-bisphosphate carboxylase (RuBPC) activity, leaf soluble protein and chlorophyll content. B. nigra is the male and female parent of B. juncea(More)
Chromium (Cr) is one of the most common heavy metals affecting the soil quality which is introduced into the environment from industries such as leather tanning, electroplating and inorganic pigment (green, orange and yellow) production. The leather industry is the major source for the environmental influx of Cr. Cleaning up of the Cr contaminated sites is(More)
Optimization is a technique through which better results are obtained under certain circumstances. In the present study maximization of heat transfer through fin arrays of an internal combustion engine cylinder have been investigated, under one dimensional, steady state condition with conduction and free convection modes. Traditional methods have been used,(More)
The present study was conducted to evaluate the ability of a high biomass producing, drought tolerant succulent plant Mauritius hemp (Furcraea gigantea Vent.) for its tolerance to different levels of Cr (0, 25, 50, 100 and 200 mg Cr kg soil(-1)) and its potential for phytoremediation purposes. Based on the data on inhibition of the growth of plants with Cr,(More)
Agave americana was evaluated for its tolerance to different levels of Cr (0, 25, 50, 100 and 200 mg kg−1 soil) and its suitability for the remediation of Cr contaminated sites. The pot culture experiment was carried out for 3 months in clay soil which was collected from 0 to 30 cm depth from the nearby agricultural field. The partitioning of Cr between(More)
