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...

Amaranthus vegetable and seeds are highly nutritious. Four species of Amaranthus were planted in pots in a glass house and leaves were harvested. Fresh leaves were analyzed for protein and carbohydrate content and oven dried leaves for Fe, Ca, K and Na contents. Protein content was varied from 6.10-9.00g/100g of fresh leaves. The amount of carbohydrate in fresh leaves of all four species varied...
