Plant growth regulator IAA (indole-3-acetic acid), besides its role in growth and development, is gaining increased attention because of its involvement in regulation of abiotic stresses. To ascertain this hypothesis, sand culture experiments were conducted to investigate the implication of IAA in regulation of Cd (cadmium) toxicity in eggplant (Solanum(More)
The sesquiterpene caryophyllene in its alcohol form has been identified for the first time from the essential oil of the tubers of Cyperus rotundus Linn. The structure of the alcohol has been identified by spectroscopic and chemical methods. Bioefficacy of the oil and its hydrocarbon, ketonic and alcoholic fractions is reported for maize and mungbean.
The effect of cadmium (Cd) on growth, photosynthesis, biochemical attributes and antioxidant enzymes activities in tomato (Solanum lycopersicum L.) seedlings was studied and the role of kinetin (KN) to ameliorate Cd toxicity was examined. Tomato seedlings were subjected to two doses of Cd viz. 3 and 9 mg Cd kgP P sand. Cadmium at both the doses(More)
Among all non-essential heavy metals, cadmium (Cd) is perhaps the metal that has attracted the most attention in soil science and plant nutrition due to its potential toxicity to humans, and also its relative mobility in the soil–plant system. In plant system, Cd influences entire metabolism. It interferes with physiological activities of plants such as(More)
The supplementation of plant hormones may enhance the tolerance capacity of plants against certain environmental stresses by increasing their physiological functioning and detoxification capacity. To answer the question that whether a phytohormone 'kinetin' (KN, 6-furfuylaminopurine), one of the artificial cytokinins could ameliorate the cadmium induced(More)
Heavy metal accumulation due to environmental pollution, especially in agricultural ecosystem can cause serious deterioration of crop yield and quality. In present study we assessed the effect of exogenous 28-homobrassinoloid (HBL; 10−8 M) on growth, photosynthesis, indices of chlorophyll a fluorescence and nitrogen metabolism in Solanum lycopersicum(More)
