the aim of this research was to improve postharvest quality and vase life of tuberose cut flowers. treatments in this experiment included: distilled water, 3% ethanol and 5% sucrose as control, thyme oil in 3 levels (50, 75 and 100 mg/l), accel in 3 level (25, 50 and 75 mg/l) and for some of flowers pulsing with 5% sucrose in first 24 hours then puting cut flowers treated with sucrose in thyme ...

A study was conducted to standardize production and postharvest handling of lily (Lilium longifolium L. cv. Mero Star). In production trial, three plant densities viz.10, 20 and 30 cm between plants in 60 cm spaced rows and two planting depths viz.7.5 and 15 cm were compared. Increased plant growth, yield and quality was recorded when plants were grown at a close spacing of 10 cm with 15 cm pla...

Ingestion, excretion and respiration in aphids were studied using artificial diets labelled with radioactive sucrose or amino acids. The rate of ingestion of a 25 % w/v sucrose diet was 12.4 nl mg-1 h-1 and the honeydew excretion rate was 5.3 nl mg-1 h-1, about 43 % of the volume ingested during the same period. The concentration of sugars in the honeydew was equivalent to 0.53 mol l-1 sucrose ...

Micro-propagation of olive provides the possibility of producing clones of native plants with appropriate attributes and mass reproduction in short period of time, compared to conventional methods. Apical dominance in olive explants limits the growth of lateral branches in vitro. The effect of Woody Plant Medium (WPM), Olive Medium (OM) and Murashig and Skoog (MS) with carbohydrate source (mann...

The multiple shoots (14.2) from Oxalis corniculata differentiated through bud breaking on MS medium with 2.0 mg/l BAP. regenerated were further sub-cultured containing 1.0 BAP and 0.5 NAA. Vegetative to reproductive phase transition occurred in the cultures affected by plant growth regulators (PGRs), sucrose concentrations, strength of salts light. Flower buds initiated half Kn + NAA 3% sucrose...

Vriesea incurvata is a native bromeliad from Brazilian Atlantic Rainforest and commercialized as an ornamental pot plant. The morphological characteristics of its floral scape may also indicate it new product to use cut flower. However, postharvest behavior was unknown. This study conducted determine vase life by applying distilled water (control) solutions containing sucrose (50 g L-1), salicy...

The present work aimed to investigate the effects of acute sucrose treatment on the perception of painful stimuli. Specifically, we sought to determine the involvement of the endogenous opioid peptide-mediated system as well as the role of the μ(1)-opioid receptor in antinociception organisation induced by acute sucrose intake. Nociception was assessed with the tail-flick test in rats (75, 150 ...

The incretin hormones, glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP), play an important role in glucose homeostasis in both health and diabetes. In mice, sucralose, an artificial sweetener, stimulates GLP-1 release via sweet taste receptors on enteroendocrine cells. We studied blood glucose, plasma levels of insulin, GLP-1, and GIP, and gastric emptying ...

Water intake of nectarivores is intrinsically linked to nectar concentration. Osmoregulation in whitebellied sunbirds Nectarinia talatala (body mass 9.3+/-0.1 g, mean +/- S.D., N=7), was examined by feeding them sucrose solutions, equivalent to extreme diet concentrations (0.07-2.5 mol l(-1) sucrose; 2-65% w/w), with and without supplementary drinking water. Total water gain was 33-515% of body...
