The latex of Calotropis gigantea is a rich source of useful components that has medicinal properties and one of the main applications is in controlling the heart muscle. The crude latex extract contained many proteins, which are highly basic in nature and exhibited strong dilatation activity. Blood vessel experiment of the latex from Calotropis gigantea was studied in the green frog (Rana hexad...

Natural products and herbal remedies used in traditional folklore medicine have been the source of many medically beneficial drugs because they elicit fewer side effects, relatively cheap, affordable and claimed to be effective. However, in order to make these remedies acceptable to modern medicine, there is a need to scientifically evaluate them to identify the active principles and to underst...

Fifteen progeny of two Polled Hereford sires were fed endophyte-infected tall fescue seed (E+) to investigate variability in susceptibility to fescue toxicosis. One sire, bred in Missouri, was reputed to produce calves that were resistant to fescue toxicosis. The Control sire, from Virginia, had unknown merit for susceptibility. There were two phases in which E+ was included in the diet (2 and ...

How plant competition varies across environmental gradients has been a long debate among ecologists. We conducted a growth chamber experiment to determine the intensity and importance of competition for plants grown in changed environmental conditions. Festuca rubra and Trifolium pratense were grown in monoculture and in two- and/or three-species mixtures under three environmental treatments. T...

The effect of different amounts of rainfall on the below-ground plant biomass was studied in three grassland ecosystems. Responses of the lowland (dry Festuca grassland), highland (wet Cirsium grassland), and mountain (Nardus grassland) grasslands were studied during five years (2006-2010). A field experiment based on rainout shelters and gravity irrigation simulated three climate scenarios: ra...

Calotropis gigantea is a big shrub; it’s looking like a small tree, sports clusters of waxy flowers that are either white or lavender in colour found. Each flower consists of five pointed petals and a small, elegant "crown" rising from the center, which holds the stamens. This articles is viewed the botanical survey and full details of the plant of calotropis gigantea. It has oval, light green ...

We examined whether the intense root competition in a rough fescue grassland plant community in central Alberta, Canada, was important in structuring plant species diversity or community composition. We measured competition intensity across gradients of species richness, evenness, and community composition, using pairs of naturally occurring plants of 12 species. One plant in each pair was isol...
