200 µM reduced germination, germination velocity index and seminal root length but had no influence on mean germination time of all groundnut cultivars. There were highly significant differences (P<0.001) in seedling emergence between non-limed and limed soils. Root length and mass were significantly (P<0.05) reduced at high soil acidity but

Germination ecology of 10 species from acidic dry grasslands and 10 species from alkaline xerothermic grasslands was studied. The seeds were subjected to different pH, iron (Fe), manganese (Mn) and aluminum (Al) treatments under controlled conditions. Effects of ionic (chlorides) and chelated forms (HBED chelates) of Fe and Mn …

number of seeds germinated to the total number of seeds tested (Ashraf & Abu-Shakra, 1978). • Germination capacity (GCp) is the percentage of seeds that have been germinated during the germination process (Labouriau, 1983) and it was tested by the formula: Where ni is the cumulative number of seeds germinated at each obser - vation.

The effect of 24-epibrassinolide on seed germination and seedling growth of Cajanus cajan (L.) Millsp. subjected to aluminium stress was investigated. 24-EBL was found to reduce the impact of Al stress on seed germination. Further, the application of 24-EBL resulted in removal of the inhibitory influence of Al on seedling growth.

Chenery - Aluminium in Plants and its Relation to Plant Pigments 123 Finally, when such a blue-flowered aluminium-accumulator is found it must be grown under aluminium-free conditions in order to determine whether its flowers will change to pink. Experiments with Plant Pigments Since Potapov (1934) found that extracts of Rhamnus sp. berries …

High aluminium content in Ultisol is the main problem in soybean cultivation from germination to planting growth phases. Priming treatment is believed to improve seed germination in a poor-growing environment . This study aimed to determine the effect of priming of soybean seeds germinated under acid medium and aluminium stress.

Aluminum (Al 3+) toxicity is one of the major factors that limit plant growth and crop yield in acid soils. The phytotoxic effects of …

The aluminium solutions were monitored weekly to keep the pH equal to 4.0 ± 0.2, using NaOH or HCl, both of them at 1 mM to provide aluminium for absorption by the seeds (about relationships between aluminium and pH see Marschner (1995)). The distilled water of the relative control treatment was renewed weekly and its pH stayed at 7.0.

Planting the Seeds. First, check out my seed starting guide post so you know exactly when to start what. The pellets hydrate pretty quickly– place them in your tray and add an inch or two of water in the bottom. They'll start expanding and should be ready in about 30 minutes.

Boron-mediated aluminium stress tolerance under aluminium toxicity at germination and early seedling stages of wheat MH Shovon, A Sagar 1, MA Mia 1, FR Rakhi, JE Tajkia 1, MH Kabir, TH Shabi 2,

Based on the effects of different aluminum (Al) concentrations (0, 50, 200, 500, and 2 000 µmol.L-1) on seed germination, seedling root growth, superoxide dismutase (SOD), …

Maize hybrids exhibit differential sensitivity to Al during germination, where main root length may be a sensitive indicator of hybrid tolerance in nutrient solution. ... Aluminium-induced growth inhibition is associated with impaired efflux and influx of H + across the plasma membrane in root apices of squash (Cucurbita pepo). Journal of ...

The effect of 28-homobrassinolide on seed germination and seedling growth of pigeon pea [Cajanus cajan (L.) Millsp.] under aluminium toxicity was studied. 28-HBL reduced the impact of Al stress on seed germination. Application of 28-HBL removed the inhibitory influence of Al on seedling growth. Homobrassinolide application enhanced proline in Al …

DonShirer Westbrook, CT (Zone 6a) Feb 20, 2012. A local deli packs frozen foods in 5"x9"x2" aluminum trays with a plastic top. They are a convenient size for starting seeds (built in moisture cover!). I used a couple that way last year with fairly good results and this year I have a whole stack of them. However I dimly remember someone on DG ...

Germination of ga1-3 seeds in the dark was stimulated by cutting the seed coat (Telfer et al., 1997). Sterilized seeds were plated in medium containing the indicated concentration of phytohormones. Plates were wrapped in three layers of aluminum foil and kept in an opaque box in the same 22°C incubator used for the germination experiments.

The aim of this work was to determine the germination parameters, to quantify the water status and growth, to assess the Al accumulation, and antioxidant enzyme activities in plants to evaluate the stress exerted by aluminum in Cucumis sativus L. For germination test, increasing doses of Al were used (0, 200, 500, 1,000, and 2,000 μM).

Aluminum (Al) toxicity in acidic soils is a major constraint for seed germination and crop growth. Pyroligneous acid (PA) is rich in bioactive compounds …

Despite the importance of soil reaction for alien plant establishment, few and incomplete studies have included this key factor so far. In this study, we investigated the effects of soil pH on the germination, growth (plant height, width, dry weight, etc.) and reproductive investment (inflorescence size and n° of flowers) of Ambrosia artemisiifolia …

Aluminium is present in soils in a variety of forms and bound to the soil constituents, particularly clay particles and organic matter. When soil pH drops, aluminium becomes soluble and the amount of aluminium in the soil solution increases. As a rule of thumb, soil aluminium concentration of 2-5 parts per million (ppm) is toxic to the roots of ...

induced seed germination with K+, Cl- and Al3+ accumulation is discussed. Introduction Germination potential of seeds is an important factor for growing plants in adverse soil condition like aluminium toxicity. There are a few reports on the effect of aluminium stress on germination of seeds. Al3+ decreased seed germination in maize (Nasr 2013 ...

Aluminium (Al) is a phytotoxic element affecting the growth and yield of many crop plants, especially in the tropics. ... The Netherlands), which will be referred to hereafter as 'saplings'. The nursery grew the plants from seeds obtained from the UK. The saplings were ca. 1–3 years old and 15–50 cm tall. The pH of the soil was ca. 5.5.

Acid soils limit crop production on 0-40% of the world's arable land and up to 70% of the world's potentially arable land (Haug, 1983). Although the poor fertility of acid soils is due to a combination of mineral toxicities (aluminum and manganese) and deficiencies (phosphorus, calcium, magnesium, and molybdenum), Aluminum toxicity is …

Aluminium is a very good heat and electrical conductor. It is also is highly rust-resistant, and is non-toxic. Aluminium can be alloyed with almost any other metal. Aluminium is inflammable, non-magnetic and non-sparking. These properties have made it an important metal in the modern world.

Lab #4 – Objectives 1. Compare and contrast the germination and TZ tests, which are used to evaluate the level of viability (i.e., whether the seeds are alive or dead) of a seed lot or a seed sample. 2. Determine the effect of temperature, moisture, and light on the germination of selected crops. 3.

Aluminum concentrations of 50–500 μM did not reduce the cumulative percent germination of seeds but impaired the ability of seedlings to become established.

The present study examined the action of nitric oxide (NO) on the germination process of rice seeds and early root growth under aluminum (Al) stress. Seeds and seedlings of two rice genotypes, with different levels of sensitivity to aluminum stress, were examined after treatment with Al and NO or only with Al. Further, the histochemical localization of Al and …
