treatment and remediation of petroleum contaminated soils using selective Ornamental Plants
Environmental Engineering Science, 2012Co-Authors: Rui Liu, Qixing Zhou, Rajendrasinh Jadeja, Zhe LiuAbstract:Abstract Pot-culture experiments were carried out to assess the phytoremediation potential of 14 Ornamental Plants in weathered petroleum-contaminated soil, which was collected in the Shengli Oil Field, one of the biggest oil fields in China, by examining their impact on the degradation potential of total petroleum hydrocarbons (TPHs) and its composition. Results showed Gaillardia aristata, Echinacea purpurea, Fawn (Festuca arundinacea Schreb), Fire Phoenix (a combined F. arundinacea), and Medicago sativa L. could effectively reduce TPHs and its composition in 10,000 mg kg−1 TPH-contaminated soil. After a 30-day pot-culture experiment, the removal rates were 37.16%, 46.74%, 49.42%, 41.00%, and 37.93%, respectively, significantly higher than that in the control (only 12.93%). Removal rates of TPH composition including saturated hydrocarbon, aromatic hydrocarbon, asphaltene, and polar compound reached 39.41%, 38.47%, 45.11%, 42.92%, and 37.52%, respectively, also higher than that in the control (only 6.90%)...

growth responses of three Ornamental Plants to cd and cd pb stress and their metal accumulation characteristics
Journal of Hazardous Materials, 2008Co-Authors: Jianv Liu, Qixing Zhou, Lena Q., Ting Sun, Song WangAbstract:Up to now, there was no document on Ornamental Plants that had been applied to phytoremediation, which can remedy contaminated environment and beautify it at the same time. Thus, the growth responses and possible phytoremediation ability of three Ornamental Plants selected from the previous preliminary experiments were further examined under single Cd or combined Cd-Pb stress. The results showed that these tested Plants had higher tolerance to Cd and Pb contamination and could effectively accumulate the metals, especially for Calendula officinalis and Althaea rosea. For C. officinalis, it grew normally in soils containing 100 mg kg(-1) Cd without suffering phytotoxicity, and the Cd concentration in the roots was up to 1084 mg kg(-1) while the Cd concentration in the shoots was 284 mg kg(-1). For A. rosea, the Cd accumulation in the shoots was higher than that in the roots when the Cd concentration in soils was <100 mg kg(-1), and reached 100 mg kg(-1) as the criteria of a Cd hyperaccumulator when the Cd concentration in soils was 100 mg kg(-1). Their accumulation and tolerance to Cd and Pb were further demonstrated through the hydroponic-culture method. And A. rosea had a great potential as a possible Cd hyperaccumulator under favorable or induced conditions. Furthermore, the interactive effects of Cd and Pb in the three Ornamentals were complicated, not only additive, antagonistic or synergistic, but also related to many factors including concentration combinations of heavy metals, plant species and various parts of Plants. Thus, it can be forecasted that this work will provide a new way for phytoremediation of contaminated soils.

ecotoxicological effects of cadmium on three Ornamental Plants
Chemosphere, 2005Co-Authors: Xiaofei Wang, Qixing ZhouAbstract:Ecotoxicological effects of cadmium (Cd) on three Ornamental Plants African marigold (Tagetes erecta), scarlet sage (Salvia splendens) and sweet hibiscus (Abebnoschus manihot) were investigated. Seeds of these Plants were exposed to five different concentrations of Cd (0-50 mg l(-1)). Ecotoxicological indexes based on inhibition rate (IC) of seed germination, root and shoot elongation, biomass (fresh weight and dry weight), as well as IC50 (Cd concentration when 50% Plants show inhibition) and tolerance indexes (the ratio of maximum root length in an experimental group to that in a control group) were determined. The results indicated that Cd had little effects (p > 0.05) on seed germination of the three Plants and shoot elongation of scarlet sage (S. splendens). Cadmium had significant (p < 0.05) inhibitory effects on root elongation of the three Plants and shoot elongation of African marigold (T erecta). The fresh weight biomass of scarlet sage (S. splendens) was most sensitive to Cd, while that of sweet hibiscus (A. manihot) was least sensitive. On a dry weight basis, African marigold (T erecta) was the least sensitive, and scarlet sage (S. splendens) was the most sensitive to Cd. Based on IC50 of seed germination, sweet hibiscus (A. manihot) was the most insensitive plant with an IC50 value as high as 428.0 g1(-1). According to Cd-tolerance indexes under the same Cd concentration, sweet hibiscus (A. manihot) was the most tolerant plant whereas scarlet sage (S. splendens) was the most sensitive one.

Disease and Insect Resistant Ornamental Plants: Buxus (Boxwood)
New York State Integrated Pest Management Program, 2019Co-Authors: Thurn Mary, Lamb Elizabeth, Eshenaur BrianAbstract:NYS IPM Type: Resistant Ornamental Plants Fact SheetBuxus is a genus of leafy evergreen shrubs and small trees commonly known as boxwood. Two of the most common types are B. sempervirens (American) and B. sempervirens ‘Suffruticosa’ (English). However, according to The American Boxwood Society, there are about 148 commercially available species and cultivars that vary greatly in size, shape, growth rate, leaf characteristics and hardiness. Known for their dense growth habit and resistance to deer-browsing, boxwoods are often grown as hedges. Boxwood blight is the most serious disease of Buxus in the landscape. Insect pests include boxwood leafminer, boxwood mite and boxwood psyllid

Disease and Insect Resistant Ornamental Plants: Ilex (Holly)
New York State Integrated Pest Management Program, 2019Co-Authors: Thurn Mary, Lamb Elizabeth, Eshenaur BrianAbstract:NYS IPM Type: Resistant Ornamental Plants Fact SheetIlex is a widely-distributed genus of over 400 species of evergreen or deciduous trees, shrubs and climbers. Holly flowers may be inconspicuous, but their distinctive foliage, colorful fruit and diverse forms provide plenty of Ornamental interest. Insect pests of hollies include leaf miners, scale and spittlebug. Diseases in nursery production are more common and include black root rot, blights and nematodes

Disease and Insect Resistant Ornamental Plants: Pyrus (Pear)
New York State Integrated Pest Management Program, 2019Co-Authors: Thurn Mary, Lamb Elizabeth, Eshenaur BrianAbstract:NYS IPM Type: Resistant Ornamental Plants Fact SheetPyrus is a large genus of shrubs and trees in the rose family. Pyrus communis, the common or European pear, is grown for its edible fruit. Pyrus calleryana, or Callery pear, originally imported from China to breed fire blight resistance into P. communis, is grown primarily for Ornamental use. The Ornamental Callery pear is one of the most widely grown trees in urban, residential and commercial landscapes. It is known for its early spring profusion of showy white flowers, fast growth and tolerance of difficult growing sites. Since the release of ‘Bradford’ in 1963, many Ornamental cultivars have been introduced. Like other rosaceous Plants, pears are susceptible to a number of diseases including fire blight, scab, rust, and leaf spot

Disease and Insect Resistant Ornamental Plants: Tsuga (Hemlock)
New York State Integrated Pest Management Program, 2019Co-Authors: Thurn Mary, Lamb Elizabeth, Eshenaur BrianAbstract:NYS IPM Type: Resistant Ornamental Plants Fact SheetTsuga, commonly known as hemlock, is a small genus of evergreen trees known for their graceful, pyramidal shape and distinctive drooping, horizontal branches. Hemlocks are used extensively in landscape plantings and are an important component of forests. Four species are native to North America–T. canadensis (Canadian or eastern hemlock), T. caroliniana (Carolina hemlock), T. heterophylla (western hemlock), and T. mertensiana (mountain hemlock). Cultivars offer a range of Ornamental options including low growing ground covers, weeping, and upright forms. Potential disease problems include needle blight, cankers, and rusts. The most serious insect threat to native hemlocks in their eastern range is the hemlock woolly adelgid
