The electrophoretic patterns of esterase (E-l), alcohol dehydrogenase (ADH), and glutamate oxaloacetate transaminase (GOT) isozymes were studied in two Spanish populations of the lily Scilla autumnalis with Bchromosome carrying individuals. The E-l isozyme activity appears only in those individuals with B-chromosomes. None of the bulbs free of B’s show it. Five bulbs, mosaic for B-content, were...

The present study was designed to study the effect of different growing media (clay, composted leaves and sand + composted leaves (1: 1 v/v) and fertilizer rates of mineral NPK (19: 19: 19) at 0.0, 2.5, 5 g / plant and their combined effect on the vegetative growth, flowering qualities, bulbs production and chemical constituents of leaves of Amaryllis (Hippeastrum vittatum, Herb.) plants during...

Epidemiological data suggest that onion (Allium cepa L.) consumption promotes cardiovascular health (Kendler, 1987). Among the salutary effects of Allium vegetables on the cardiovascular system is the inhibition of platelet activity (Ariga et al., 1981; Goldman et al., 1995; Kiesewetter et al., 1991; Makheja et al., 1980), thus reducing clotting time and promoting blood circulation. To my knowl...

BACKGROUND AND AIMS Survival of many herbaceous species in Mediterranean habitats during the dry, hot summer depends on the induction of summer dormancy by changes in environmental conditions during the transition between the winter (growth) season to the summer (resting) season, i.e. longer days, increasing temperature and drought. In Poa bulbosa, a perennial geophytic grass, summer dormancy i...

Antioxidant activity of fresh Allium sativum L. (garlic) is well known and is mainly due to unstable and irritating organosulphur compounds. Fresh garlic extracted over a prolonged period (up to 20 months) produces odourless aged garlic extract (AGE) containing stable and water soluble organosulphur compounds that prevent oxidative damage by scavenging free radicals. The aim of this study was t...

Ultraviolet radiation (UVR) is hazardous to patients with photosensitive skin disorders, such as lupus erythematosus, xeroderma pigmentosum and skin cancer. As such, these patients are advised to minimize their exposure to UVR. Classically, this is accomplished through careful avoidance of sun exposure and artificial tanning booths. Indoor light bulbs, however, are generally not considered to p...

The experiments were carried out at the Regional Agricultural Research Station, Rahmatpur, Barisal during the rabi seasons of 2001-2002 and 2002-2003 to study the impact of different sulphur levels on bulb yield, storability and economic return of onion. Sulphur application had significant effect on yield components and bulb yield of onion. The highest bulb yields (19.75 and 19.88 t/ha) were ob...

Maximum oxygen uptake and the running speed at the anaerobic threshold were determined during treadmill running. Performance in these laboratory tests and performance on a squash-specific field test were compared and examined with respect to subjective ratings of squash fitness. The field test was performed in a squash court. Six light bulbs were connected to a programming device causing indivi...

This work presents an experimental study that investigates the behavoir of both conventional and under-reamed piles embedded in a single layer sand with varying relative densities examines different soil layers, subjected to pullout static monotonic loading. The focuses on influence spacing ratio between under-reams number bulbs pile's ultimate load. A uniform pile stem, bulb, twin were three v...
