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 ...

Phytotoxic effect of aluminum and chromium on the germination and early growth of wheat (Triticum aestivum) varieties Anmol and Kiran
A greenhouse experiment was conducted to determine the phytotoxic effect of aluminum and chromium on the germination and early growth of two wheat (Triticum aestivum) varieties Anmol and Kiran. Seed were treated with 40, 80, 120 and 160 ppm of aluminum and chromium solution individually and in combined form. Observations were made on seed germination, root, shoot and seedling length, and dry ...

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 ...

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 ...

Advantages of heating mats in seed germination
Advantages of heating mats in seed germination Germinator and heated seedbed. Is seed germination uneven and inconstant? Every time you try to germinate seeds then the seedlings do not germinate or eventually dry up. You should know that not everyone has a green thumb or the right equipment. So what do you do? You give up, just like any inexperienced and hopeless gardener would. But it’s ...

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 ...

Seed Seedling Bluetooth Temperature Recorder
Seed seedlings have strict requirements on environmental temperature. Only at a suitable temperature can seeds grow normally. Bluetooth temperature loggers are used for temperature monitoring and can help ensure that seeds germinate and grow under the right temperature conditions. Seed seedlings are generally carried out in greenhouses, which can effectively control the environmental temperature ...

Emergence of polymer-coated corn and soybean influenced by tillage and sowing date
No tillage often delays soil warming and drying, thus sowing too early in the spring may compromise seed viability due to prolonged exposure to cold and wet soil in the northern Corn Belt. Coating seed with a temperature-activated polymer may circumvent the adverse effects of exposing seeds to cold and wet soil. Germination and emergence of noncoated and polymer-coated corn (Zea mays L.) and ...

Soil seed bank composition in pastures of diverse mixtures of temperate forages
Seed banks may contribute useful or weedy species that fill gaps in pastures. In a previous study, pastures planted to complex mixtures of forages had a lesser proportion of weedy species in the aboveground vegetation. In this study, we relate changes in the species composition of the seed bank to changes in the aboveground vegetation. In August 2001, four mixtures [two, three, six, and nine ...

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 ...

Increased inbreeding and inter-species gene flow in remnant populations of the rare Eucalyptus benthamii
Eucalyptus benthamii Maiden & Cambage is a forest tree of interest for conservation and plantation forestry. It is vulnerable to extinction, occurring on the alluvial floodplains of the Nepean River and its tributaries, south-west of Sydney, Australia. These floodplains were largely cleared of native vegetation for agriculture by the mid-1800s. Flooding of the Cox Valley for Sydneys water supply ...

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 ...

Our Spacer: a versatile solution for hydroponic crops
In vegetable crops in particular, there are a number of tried and tested advantages to using our Spacers in hydroponic farming. They include providing a means of lifting the substrate away from the drainage stream whilst providing excellent aeration and avoiding a build-up of humidity below the substrate. These advantages have led to Spacers also being used with other applications and in other ...

The value of seed harboured in Mediterranean temporary ponds
Temporary ponds and their varying water levels provide the conditions for valuable wildlife habitat. A study in Crete, conducted under the LIFE-Nature project1 Actions for the Conservation of Mediterranean Temporary Ponds in Crete, has demonstrated these ponds contain varied collections of seeds and that these ‘seed banks’ could play an important role in vegetation recovery after ...

Conservation: It’s the right thing to do
A fable of six blind men and an elephant originated centuries ago somewhere on the Indian continent. In it the blind men try to identify an elephant by touching only one part. According to the fable each man came to a different conclusion as to what the elephant was. The parable illustrates that though opinions may vary, there’s some truth to be found in all of them. That’s the way ...
