Amelioration of Mn toxicity by Brassinosteroids in Brassica juncea L.
The effects of 28-homobrassinolide (28-homoBL) on protein content and antioxidative enzyme activities in 7-days old Brassica juncea L. seedlings were studied. The seeds pre-treated with different concentrations of 28-homoBL were germinated in Petriplates supplied with various concentrations of heavy metal (Mn). The activities of superoxide dismutase, catalase, ascorbate peroxidase, guaiacol ...

Potential utilisation of pulp and paper mill biosolids in composting and plant production: a case study at St. Marys Papers Ltd. (Canada)
The use of St Marys Paper biosolids as a soil additive or growth cover was investigated. Biosolids were mixed with a commercial potting media in five vol/vol ratios and employed in a greenhouse study. The biosolids were found to improve Pinus banksiana seedling growth, a 50% biosolids:50% ProMix mixture yielding the tallest plants and highest dry mass. To further biologically stabilise the ...

Effect of aluminum and chromium on the growth and germination of mesquite (Prosopis juliflora swartz.) DC.
Abstract: Prosopis seeds were grown under controlled environment in solution of aluminum and chromium at different concentration alone as well as combined together. The effect of these metals was studied on seed germination, root length, shoot length, seedling length and dry biomass. Aluminum and chromium alone, and combined together showed no effects on germination and dry biomass. Chromium ...

Combined effects of bisphenol A and cadmium on growth and nitrate assimilation of soybean seedling roots
Bisphenol A (BPA) and cadmium (Cd) pollution exist simultaneously in many regions. However, little information is available regarding the combined effects of BPA and Cd pollution on plants. Plant roots are in direct contact with the soil, which is an important compartment of BPA and Cd. Here, the effects of combined BPA and Cd pollution on soybean seedling roots were evaluated in pot ...

Germination and seedling growth of corn (Zea mays l.) under varying levels of copper and zinc
The heavy metal tolerance in corn (Zea mays L.) var. ‘Neelum’ was assessed at germination and seedling growth after having subjected it to different concentrations of CuSO4 and ZnSO4. Germination was not affected by any of the metal tested, whereas initial growth was strongly inhibited by increasing concentrations of ZnSO4. Seedlings developed toxicity symptoms in the presence of both metals but ...

Inhibition of seed germination and seedling growth of Triticum aestivum L. by industrial wastewaters
The present study was undertaken to determine the effect of different concentrations of wastewaters treated with Pseudomonas putida on various growth indices of durum wheat (Triticum aestivum L.) seeds. Significant decreases in terms of root and leaf growth were observed. The phytotoxicity of textile wastewater was more pronounced on initiation times, germination percentages, root and leaf ...

Ecotoxicological responses of three ornamental herb species to cadmium
Cadmium is one of the most toxic elements. The ideal vegetal cover should be ensured by the selection of appropriate plant species for successful phytoremediation. In the present study, the ecotoxicological effects of Cd on the following 3 ornamental herbs were investigated: Italian ryegrass (Lolium multiflorum Lam.), white clover (Trifolium repens L.), and alfalfa (Medicago sativa L.). Based ...

What are the advantages of using rabbit manure as organic fertilizer?
Nutrient content of rabbit feces Rabbit manure is a kind of high efficient organic fertilizer, the content of nitrogen, phosphorus and potassium is significantly higher than other animal manure. The nitrogen content of rabbit manure is 1.53 times of chicken manure, 3.29 times of sheep manure, 3.83 times of pig manure, the phosphorus content is 2.88 times of chicken manure, 4.6 times of sheep ...

3-D Woven Technology: The “Next Generation” in Turf Reinforcement Mats
The designers at Propex have taken the technology in their high performance turf reinforcement mats (HPTRMs) and used it to design the next generation of turf reinforcement mats (TRMs). These new netless, composite-free three-dimensional woven TRMs are designed to deliver superior, long-term performance, and are proven to outperform traditional methods like rock riprap, concrete paving and first ...

N-(N-butyl)thiophosphoric triamide/NBPT
Urease inhibitor is a kind of substance that can inhibit the activity of soil urease, and it is a new technology which has been studied in urea or nitrogen compound fertilizer. Using soil urease inhibitor can effectively slow decomposition of urea into ammonia process, reduce soil NH4 + and NH3 concentration, soil fertility and crop fertilizer synchronization. NBPT is the most effective inhibitor ...

N-(N-butyl) Thiophosphoric Triamide Solution
N-Butylthiophosphoric triamide (NBPT, hereinafter referred to as "NBPT") is currently one of the most effective soil urease inhibitors. Agricultural fertilizers, mainly nitrogen fertilizers, are quickly decomposed by urease in the soil under normal use. This not only wastes a lot of nitrogen fertilizer resources, but also increases the cost of crop production, and brings a series of problems such ...

Effect of aluminum and chromium on the germination and growth of two Vigna species
Abstract: The study deals with the effect of metal toxicity (aluminum, chromium and combination of both the metals) on seed germination, root length, shoot length, seedling length and dry biomass of Vigna radiata and V. sinensis. Chromium adversely affected the seedling by significantly reducing the growth whereas aluminum did not show such effect in both the species. Percentage of germination ...

Cotton Planting date: yield, seedling survival, and plant growth
New cultivars, changes in technology and production practices, and climate change may have altered the optimal planting time for cotton (Gossypium hirsutum L.) in the midsouthern United States. A field experiment was conducted from 2002 through 2005 on Gigger silt loam to define planting date (PD) effects on selected cotton cultivars. Six cultivars in 2002 (Deltapine DP555BR and Delta Pearl, ...

Fertilization of pinus pinea L. seedlings with a sewage sludge-based compost
Two experiments were conducted to evaluate the effect of a sewage sludge-based compost (SSC) on the growth and mineral composition of containerized Pinus pinea L. seedlings. In the first experiment, five different substrates were tested: four binary mixtures of SSC and peat (100% SSC, 75% SSC, 50% SSC and 25% SSC, by volume) without fertilization, and a control substrate (peat-based substrate + ...

Effects of low concentrations of herbicides on full-season, field-grown potatoes
Current phytotoxicity plant test protocols for US pesticide registration require testing for effects on seedling emergence and early growth without regard to other important factors, such as plant reproduction. Yield and quality reduction can have significant economic and ecological effects. Therefore, field trials were conducted to determine if potato (Solanum tubersum L.) vegetative growth and ...

Varietal differences in the growth of rice seedlings exposed to perchlorate and their antioxidative defense mechanisms
A hydroponic experiment was conducted to investigate the perchlorate (ClO4‐) phytotoxicity in different rice varieties. Considerable variations were observed when 24 rice varieties were treated with ClO4‐. The shoot height, root length and biomass of most varieties were significantly reduced by ClO4‐. The roots were more sensitive than the shoots. Hierarchical clustering analysis demonstrated ...
