Hexane, chloroform and ethanol extracts of Malva parviflora L. and Malvastrum coromandelianum L. were tested for their antibacterial, antifungal and irritant activities. While the hexane, chloroform, ethanol and aqueous extracts along with the polar mass of Amaranthus viridis L. were tested for above activities, except that of the antifungal. The extracts of Malva parviflora L. and Malvastrum c...

Both heat and chilling caused reduction in membrane protein thiol level and increased accumulation of thiobarbituric acid reactive substances in 72 hr old germinating tissues (indicators of oxidative stress) and reduced germination and early growth performances. Calcium chelator EGTA [Ethylene glycol-bis (2-aminoethylether)-N, N,N',N, tetra acetic acid] calcium channel blocker LaCI3 (Lanthanum ...

The current experiment was conducted for the simultaneous determination of several water-soluble vitamins like riboflavin (vitamin B2), niacin (vitamin B3), pantothenic acid (vitamin B5) and pyridoxine (vitamin B6) in five highly consumed local leafy vegetables named as bottle gourd leaves (Lagenaria vulgaris) (local name Lau shak), green amaranth leaves (Amaranthus viridis) (local name Data sh...

Phytoremediation of soils contaminated with cadmium was tested after liming (CaO) or biochar addition, using red amaranth (Amaranthus tricolor L.) as test plant species. Two biochars with contrasting characteristics were prepared from two feedstocks and added to the soil at a rate of 3% (w:w): Eucalyptus pyrolysed at 600°C (EB) and poultry litter at 400°C (PLB). Liming was carried out in two tr...

Tropical leaf vegetables are grown in the tropics and are rich sources of nutrients, particularly minerals, and vitamins (Oomen and Grubben 1978). A number of species and cultivars have been introduced and grown in the continental US on a limited-scale, particularly in the southern region (Lamberts 1993). The US is a major market for tropical and specialty greens and most of the shipments come ...

BACKGROUND The genus Gavialis comprises a single living but endangered species, G. gangeticus, as well as fossil species recorded in the Miocene to Pleistocene deposits of the Indian subcontinent. The genus is also represented in the Pleistocene deposits of Java by the species G. bengawanicus, which was recently recognized to be valid. Surprisingly, no detailed report of the genus exists betwee...

Extracts from ripe fruit and seeds of Sorbus aucuparia inhibit germination of other seeds, tested with Amaranthus caudatus and Lepidium sativum. The main compound of the “neutral fraction” of fruit extracts is the lactone compound parasorbic acid (4 —7 mg/g fresh weight) which inhibits germination at concentrations > 5x1C T 4 m. The “acid fraction” contains abscisic acid (1 .3—2.5 ^ / g fresh w...

Amaranthus tuberculatus is a troublesome weed in corn and soybean production systems in Midwestern USA, due in part to its ability to evolve multiple resistance to key herbicides including 4-hydroxyphenylpyruvate dioxygenase (HPPD). Here we have investigated the mechanism of resistance to mesotrione, an important chemical for managing broadleaf weeds in corn, in a multiple herbicide resistant p...
