Abstract:

Abstract Combining biomass harvest with forest fuel reduction may reduce the costs of fuel treatments. Our objectives were to determine the impact of combined biomass/fuel reduction harvests on the pools of forest fuels and to determine whether biomass harvest reduced the cost of mechanical fuel treatments. We tested two potential biomass harvest systems in wildland–urban interface areas with forest fuel accumulations on the Superior National Forest in Minnesota. Both systems performed similarly in terms of cost and efficiency at harvesting biomass. Overall, the cost of biomass harvest was imp

Abstract:

Red-fleshed pitaya is an attractive fruit not due only to the color of its flesh and skin, but also the scaly shape of its skin. In addition to being a source of vitamins and minerals, it has high commercial value and represents an alternative for cultivation in semiarid regions. Information about the post-harvest physiology of pitaya, which interferes with its ripening, allows the adoption of preservation and quality-maintenance practices. This study examines the respiratory activity and post harvest alterations of pitaya picked in the commercially immature stage of ripeness, by comparing the

Fifty-four percent of the heavily cut pine stands were at least 60% stocked with pine following harvest. The overall rate of replacement for pine stands was 78%. South. J. Appl. For. 14(2):59-63.

Abstract ‘Cortland’ apples (Malus domestica Borkh.) from both exterior and interior of large trees were harvested over a 25-day period, and samples were stored for 0 to 5.5 months in air at 0°C.

Hexane extracts of whole fruit were used to estimate α-farnesene and conjugated trienes after 1 to 4 months of storage; these values were correlated with scald development after 3 to 5.5 months of storage, α-Famesene increased during the first 2 months of storage and then decreased, while conjugated trienes increased progressively with storage time.

This study was conducted to determine if different harvesting methods would affect greater retention of antioxidant activity (AOA) of sage. The harvesting methods evaluated included sickle harvest, hand harvest, and flail harvest. Harvested samples were air-dried (temperature range 15 to 49C) and oven-dried (continuous 49C). Leaf area analysis indicated that flail harvesting induced substantial chopping and size reduction of the harvested material. AOA of sample extracts was measured

Whole onions harvested before June showed higher values of general ingredients, inorganic ingredients, organic acids, spiraeoside, quercetin, total chlorophyll, and antioxidant activity than bulbs harvested in June.

Abstract:

The objective of this study was to evaluate the effect of harvest at different times of day on the chemical and physical characteristics of vegetable-type soybean BRS 267 cultivar, harvested at the R6 stage (seed development) and to compare it with that on the grains harvested at the R8 stage (maturation). The pods of the BRS 267 cultivar were harvested at the R6 stage (at 8:00 AM, 12:00 AM, and 6:00 PM), the color parameters were evaluated, and the grains were analyzed for chemical composition, activity inhibitor trypsin, phytic acid content, starch, sugars, fatty acids, and isoflavones.

Abstract:

Sorbitol dehydrogenase (SDH) is a key enzyme in apple fruit converting sorbitol into fructose. SDH activity in `Fuji' apple was reported to increase close to harvest, perhaps as part of the ripening process. Aminoethoxyvinylglycine (AVG) is used to delay fruit ripening and prevent fruit drop, though its effect on sorbitol metabolism is not known. To determine if the late season increase in SDH activity is common among apple cultivars and if AVG use affects SDH expression and activity, AVG was applied to `Lodi', `Redchief Delicious', and `Red Fuji' trees 4 weeks before harvest.

Yacon tubers are of global interest due to their prebiotic potential while yacon leaves contain phenolic compounds with potential health benefits. In Kenya, yacon is a newly introduced root crop that is of interest to consumers; however, their main challenge to consumption is determining the appropriate time to harvest the leaves. The chemical makeup of yacon leaves varies depending on the planting site, growing season, harvest time, and growth stages. The current research determined the impact of varying stages of maturity on the chemical composition and antioxidant potential of yacon leaves

Post-harvest handling is carried out only after the harvest of fruits and vegetables. The harvesting method varies according to the nature of the crop and also based on the availability of resources. Fruits and vegetables have a limited shelf-life. So, they must be harvested at the proper stage of maturity. Post-harvest quality and shelf-life of fruits and vegetables mainly depend upon handling practices and various treatments been carried out after harvest. Poor handling practices and lack of various treatments lead to post-harvest loss. Losses in vegetables mainly occur due to direct packagi
