(Springer, 2017)We explored the phytotoxicity of Callistemon viminalis leaf extracts (LE; 0.5, 1, 2 and 4%) towards germination and early growth of rice (Oryza sativa L.) and its associated weeds [Echinochloa crus-galli (L.) Beauv., Cyperus ... -
Tolerance and hyperaccumulation of cadmium by a wild, unpalatable herb Coronopus didymus (L.) Sm. (Brassicaceae)
(Academic Press, 2017)The potential of a wild, unpalatable plant Coronopus didymus was investigated for the first time in terms of its capability to tolerate and accumulate cadmium (Cd) for phytoremediation purposes. A screenhouse experiment ... -
Comparative account of allelopathic potential of essential oil of Tagetes minuta L. and its major component cis-β-Ocimene
(AdhyaBiosciences, 2016)The study aims to explore the chemical composition of volatile essential oil of Tagetes minuta and comparison of its allelopathic potential with cis-β-ocimene, a major component of oil. T. minuta L. is an exotic aromatic ... -
Effect of lead on oxidative status, antioxidative response and metal accumulation in Coronopus didymus
(Elsevier Masson SAS, 2016)A screenhouse experiment was conducted to assay the effect of Lead (Pb) on oxidative status, antioxidative response and metal accumulation in Coronopus didymus after 6 weeks. Results revealed a good Pb tolerance and ... -
EMF radiations (1800 MHz)-inhibited early seedling growth of maize (Zea mays) involves alterations in starch and sucrose metabolism
(Springer, 2016)The present study investigated the impact of 1800-MHz electromagnetic field radiations (EMF-r), widely used in mobile communication, on the growth and activity of starch-, sucrose-, and phosphate-hydrolyzing enzymes in Zea ... -
Allelopathic Effect of Leaves of Invasive tree Broussonetia papyrifera against some crop plants
(AdhyaBiosciences, 2016)Allelopathic effect of aqueous extracts of leaves of Broussonetia papyrifera (L.) Vent. was studied on germination and seedling growth of Triticum aestivum L. and Oryza sativa L. under laboratory conditions. The seed ... -
Mapping ‘consistency’ in India’s climate change position: Dynamics and dilemmas of science diplomacy
(Springer, 2015)India’s position on climate change negotiations is likely to have far reaching implications for the success of global climate cooperation. Since the beginning of negotiations, the principle of equity and common but ... -
Allelopathic effect of Pinus roxburghii on an understorey plant, Bidens pilosa
(AdhyaBiosciences, 2016)Allelopathic effect of Pinus roxburghii was studied on Bidens pilosa through laboratory and greenhouse experiments. The aqueous extracts of green needles, needle litter and bark were found to inhibit germination and initial ... -
Allelopathic potential of needle litter extracts of Pinus roxburghii on germination and early growth of Zea mays and Echinochloa crus-galli
(Indian Journal of Applied Research (IJAR), 2016)The needle litter of Pinus roxburghii, a common conifer of Himalayan region was investigated for allelopathic potential against crop plant Zea mays and weed Echinochloa crus-galli. The aqueous extracts from litter enhanced ... -
Exogenous Nitric Oxide (NO) interferes with lead (Pb)-induced toxicity by detoxifying reactive oxygen species in hydroponically grown wheat (Triticum aestivum) roots
(Public Library of Science, 2015)Nitric Oxide (NO) is a bioactive signaling molecule that mediates a variety of biotic and abiotic stresses. The present study investigated the role of NO (as SNP [sodium nitroprusside]) in ameliorating lead (Pb)-toxicity ... -
