| remediation and reclamation of soils heavily contaminated with toxic metals as a substrate for greening with ornamental plants and grasses. | soils highly contaminated with toxic metals are currently treated as waste despite their potential inherent fertility. we applied edta washing technology featuring chelant and process water recovery for remediation of soil with 4037, 2527, and 26 mg kg(-1) of pb, zn and cd, respectively in a pilot scale. a high edta dose (120 mmol kg(-1) of soil) removed 70%, 15%, and 58% of pb, zn, and cd, respectively, and reduced human oral bioaccessibility of pb below the limit of quantification and that of ... | 2015 | 25577699 |
| ornamental plants as sinks and bioindicators. | mitigation of urban air pollution is a big challenge, especially for the metropolitan cities of the world. in an indian metropolis like delhi, even after the implementation of several control policies, no such remarkable change has been observed in its air quality. globally, afforestation or greenbelt development is an effective and well-recognized pollution abatement process. the aim of our present study was to examine the biochemical response of some naturalized ornamental plant species, viz. ... | 2014 | 24617064 |
| land-use change in indian tropical agro-ecosystems: eco-energy estimation for socio-ecological sustainability. | this study was carried out to understand the ecological and economic sustainability of floriculture and other main crops in indian agro-ecosystems. the cultivation practices of four major flower crops, namely jasminum multiflorum, crossandra infundibuliformis, chrysanthemum and tagetes erecta, were studied in detail. the production cost of flowers in terms of energy was calculated to be 99,622-135,996 compared to 27,681-69,133 mj ha(-1) for the main crops, namely oryza sativa, eleusine coracana, ... | 2017 | 28315232 |
| catellatospora tagetis sp. nov., isolated from the root of a marigold (tagetes erecta l.). | a gram-stain positive, non-motile, mesophilic actinomycete, designated strain neau-yjc4(t) was isolated from the root of a marigold (tagetes erecta l.) collected in heilongjiang province, northeast china, and characterized using a polyphasic approach. morphological and chemotaxonomic properties of strain neau-yjc4(t) were consistent with the description of the genus catellatospora. 16s rrna gene sequence similarity studies showed that strain neau-yjc4(t) belongs to the genus catellatospora, bein ... | 2015 | 26111852 |
| streptosporangium subfuscum sp. nov., isolated from the rhizosphere of marigold (tagetes erecta l.). | a gram-stain positive, filamentous bacterial strain, designated strain neau-twsj13(t), was isolated from the rhizosphere of a marigold (tagetes erecta l.) plant collected in heilongjiang province, northeast china, and characterized using a polyphasic approach. the strain was observed to form abundant aerial hyphae differentiated into spherical sporangia. 16s rrna gene sequence similarity studies showed that strain neau-twsj13(t) belongs to the genus streptosporangium, being most closely related ... | 2014 | 25256952 |
| isotopic fractionation associated with symbiotic n(2) fixation and uptake of no(3) by plants. | isotopic fractionation associated with n(2) fixation and no(3) (-) uptake by plants are relevant to the accuracy of estimates of n(2) fixation based on differences in the natural abundance of (15)n between n(2) fixing and nonfixing plants. the isotope effect on n(2) fixation by soybeans (glycine max [l] merrill, variety harosoy) and red clover (trifolium pratense [l]) was determined from the difference in (15)n abundance between atmospheric n(2) and the total n of plants grown hydroponically wit ... | 1980 | 16661392 |
