Although theories in both evolutionary biology and economics predict that an individual’s health should be associated with the individual’s time preference, no prior study has been done to empirically support or refute such predictions. By collecting detailed measures of health, time preference, and expected longevity on a sample of individuals in townships around Durban, South Africa, this stu...

1-mcp, as an ethylene action inhibitor, significantly delayed the wilting of cut carnation.this study was carried out to determine the optimum concentration and duration of 1-mcp application on vaselife of cut carnation c.v 'tempo'. six levels of 1-mcp concentrations (0,20,40, 60, 80 and 100 nl.1-1) as well as three application times (3, 6 and 9 hours) were studied in a factorial comp...

Abstract Floriculture is a promising activity and has great economic importance. In this context, the cultivation of Lilium pumilum Redouté stands out. However, one main challenges flower farmers face that large part products lost before reaching final consumer, due to postharvest losses. Such losses can be minimized by adopting some techniques, such as use conditioning solution (pulsing), whic...

The antioxidant properties of hot-water extracts from a dried chili pepper were maintained through the postharvest ripening process at 10 degrees C for 18 months. In order to isolate the antioxidant from the ripe pepper, we fractionated hot-water extracts by size-exclusion gel chromatography. A certain fraction showed antioxidative activity via the 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical-s...

In this paper, the main problem and countermeasure of fruit production quality and safety were studied in Yanshan Mountain. The subjective factor was fruit farmer quality and safety consciousness faint, and the objective factors were: severe orchard environmental pollution, faint fruit postharvest handling, lag in process technology, fruit quality determination and market inspection system is n...

Calcium is thought to be the most important mineral element determining fruit quality. It seems to be especially important in apples where it has been shown to reduce metabolic disorders. Calcium in adequate amounts helps to maintain apple fruit firmness and decreases the incidence of physiological disorders such as water core, bitter pit and internal breakdown. Postharvest decay may also be re...

Light-emitting diodes (LEDs) are characterized by their narrow-spectrum, non-thermal photon emission, greater longevity, and energy-saving characteristics, which are better than traditional light sources. LEDs thus hold the potential to revolutionize horticulture lighting technology for crop production, protection, and preservation. Exposure to different LED wavelengths can induce the synthesis...

In March 2014, a kohlrabi stem rot sample was collected from the cold storage room of Daegwallyong Horticultural Cooperative, Korea. White and fuzzy mycelial growth was observed on the stem, symptomatic of stem rot disease. The pathogen was isolated from the infected stem and cultured on potato dextrose agar for further fungal morphological observation and to confirm its pathogenicity, accordin...
