Invasion success by an alien species is dependent upon rate of reproduction, growth, mortality, physical characteristics of the environment, and successful competition for resources with native species. For sessile, epibenthic marine species, one critical resource is space. We examined competitive success in two invasive Indo-Pacific corals involved in competition for space in the northern Gulf...

Selenium deficiency in humans has been associated with various diseases, the risks of which can be reduced through dietary supplementation. Selenium accumulating plants may provide a beneficial nutrient for avoiding such illnesses. Thus, leafy vegetables such as Amaranthus hybridus, Amaranthus sp., Cucurbita maxima, Ipomoea batatas, Solanum villosum, Solanum scabrum, and Vigna unguiculata were ...

According to the importance and diversity of Chenopodium album, Cynodon dactylon and Amaranthus retroflexus in safflower fields and significant role of safflower (Carthamus tinctorius L.) as an oil seed, an experiment was conducted using CRD based factorial design with three replications to study the allelopathic effects of root and shoot extracts of these weeds on germination and early growth ...

A few decades ago Amaranthus was rediscovered as a most promising plant genus that may provide high-quality protein, unsaturated oil, and various other valuable constituents. Since then research has focused on various Amaranthus spp. and has been rapidly expanding, and a large number of reports have been published. Several review articles focusing on different aspects, such as botanical, agrote...

Background Amaranthus pollen grains are known to be highly allergenic and a potential cause of respiratory allergic diseases in many countries. Amaranthus palmeri pollen is an important allergenic source in Mexico; however in our country, there is not reported data about the prevalence of these pollens. The first allergenic profilin was identified from birch pollen allergen (Bet v 2) in 1991. M...

Methanolic extract of whole plant of Amaranthus viridis L (MEAV), was screened for antinociceptive activity using acetic acid induced writhing test, hot plate test and tail immersion test in mice. In a similar way a screening exercise was carried out to determine the antipyretic potential of the extract using yeast induced pyrexia method in rats. Administration of the extracts was applied to bo...

Different formae speciales of Fusarium oxysporum are the main causal agent of Fusarium wilts. In 2008 and 2009 we collected F. oxysporum samples from symptomless Abutilon theophrasti, xanthium strumarium, Chenopodium album, Matricaria perforata, Ambrosia artemisiifolia, Polygonum lapathifolium, Sonchus arvensis, Amaranthus blitoides, Amaranthus retroflexus, Datura stramonium, Sorghum halepense ...

Ascorbic acid contents of some fruits and vegetables in Abakaliki were analyzed through titrimetric methods. The results recorded the concentrations (mg/100g) of ascorbic acids in various fruits as orange (15.47 ± 0.23), lemon (12.87 ± 0.45), grape (2.00 ± 0.10), paw-paw (46.40 ± 1.65), apple (2.20 ± 0.10), banana (1.87 ± 0.06), carrot (1.80 ± 0.04), pineapple (2.80 ± 0.10), water melon (2.27 ±...

Genetic diversity and relationships among 12 cultivated and wild Amaranthus species were examined using protein and RAPD markers. High level of genetic diversity was common within species contrary to genetic uniformity within most accessions. On average, the polymorphism reached 42.60% among the cultivars but raised to 46.88% in the wild counterpart. The seed protein content varied in the 11.80...
