CONTEXT Prunella vulgaris L. (Labiatae) is a perennial plant common in China and Europe and is rich in rosmarinic acid (RA), ursolic acid (UA), and oleanolic acid (OA). The dried spica of P. vulgaris has been used as traditional medicine in China for over a hundred years. To our best knowledge, no study has been conducted to determine the influence of harvesting time on concentrations of bioact...

application of ethephon is an effective way in increase of grape fruits quality. in this study the effect of preharvest application of ethephon solution at four levels (0, 150, 250 and 300 mg/l)and application time at two levels (10-20% and 50-70% of berry coloring), were evaluated on quality indices of ghizil uzum grape cultivar at harvest time. evaluated indices were soluble solids content, t...

Th e objective of this study was to develop postharvest techniques and technologies of the most important root vegetables: carrots, celeriac and parsnip. Investigations included the eff ect of harvest maturity (harvest at November or January) and postharvest washing treatments (hot water, H2O2 and NaOCl and non-washedcontrol) of carrots (Daucus carota ’Bolero F1’), parsnip (Pastinaca sativa ‘Ba...

Local perforator flaps have evolved over the time to provide complete and stable coverage of soft tissue defects. Technical advances and experience with the perforator flaps have allowed the harvest of local perforator flaps in a free style manner by offering greater freedom in flap selection. We have proposed a technical modification in the harvest of a perforator flap by relo-cating the perfo...

1. The harvest of wild non-timber forest products (NTFP) represents an important source of income to millions of people world-wide. Despite growing concern over the conservation of these species, as well as their potential to foster forest conservation, information on the ecological implications of harvest is available only in disparate case studies. 2. Seventy studies that quantify the ecologi...

In this study the effects of plant growth regulators including; GA3 (0 and 50 mg/l) and ethephon (0 and 500 mg/l) were studied on the quality properties of two grape cultivars (Perlette and Yaghuti). At the harvest time, some physicochemical characteristics such as fruit cluster weight, fruit diameter, length, volume and L/D ratio, flesh firmness, fresh weight, TA, pH, TSS and fruit color were ...

We describe and assess several methods for scheduling fuel management treatments to achieve timber harvest and landscape pattern goals across space and time. Four landscape patterns of management activities are modeled (dispersed, clumped, random, and regular). The intent is to examine the effects of spatial and temporal placement of fuel management activities on resulting wildfire behavior. Th...

We consider the harvest of a certain proportion of a population that is modeled by an integro-difference equation. This model is discrete in time and continuous in the space variable. The dispersal of the population is modeled by an integral of the population density against a kernel function. The control is the harvest, and the goal is to maximize the profit. The optimal control is characteriz...

The impact of chemical desiccation on yield showed contrasting results depending on seedmoisture content at the time of application. Its effects on seed deterioration are still unknownand could be modified by seed composition. Objectives were to evaluate the impact of chemicaldesiccation on: i) hybrid sunflower seed yield and composition at harvest time, ii) seeddeterioration during long-term s...
