rapeseed cultivation in iran is growing rapidly while this product has been facing specific problems. every year a significant portion of edible oil is imported to the country from other countries. despite this deficit, a great amount of canola is being lost every year. therefore, in compliance with technical points, adding a suitable platform to the exisiting machineries may reduce the losses....

Embelin (2,5-dihydroxy-3-undecyl-2,5-cyclohexadiene-1,4-benzoquinone) is a phenolic compound found in the fruits of Embelia tsjeriam-cottam and is responsible for the medicinal properties of the plant Thus the fruits are harvested at a large scale before maturity leading to depletion of population. Since the chemical constituents of medicinal plants are directly associated with the harvesting t...

The intense harvesting of a fish stock can be accompanied by changes in certain life history traits of that stock. For example, after heavy exploitation, Atlantic cod (Gadus morhua) in the northwestern Atlantic and haddock (Melanogrammus aeglefinus) on the Scotian Shelf matured at smaller sizes and younger ages (Olsen et al., 2004, 2005; Neuheimer and Taggart, 2010). Because earlier maturing in...

abstract having no exact knowledge of most appropriate harvesting time in kiwifruit grown in different regions of guilan province, as well as the low storage longevity of the fruits are the most important factors causing considerable reduction in both marketability and export affairs. in this study, the influence of fruit quality in term of harvesting time on the postharvest quality and food va...

The quick and non-detective detection of agriculture product is one of the measures to increase the precision and productivity of harvesting and grading. Having analyzed H frequency of different maturities in different light intensities, the results show that H frequency for the same maturity has little influence in different light intensities; Under the same light intensity, three strawberry m...

in order to investigate the effect of irrigation intervals and harvesting time on yield and yield components of anise (pimpinella anisum l.) a field experiment was conducted at the agricultural research station, university of zanjan in 2010. for this purpose a spilt-plot experiment based on complete randomized block design with three replications was used. three irrigation intervals (every 7, 1...

Harvesting grapes at the appropriate maturity is key to production of high quality red wines. Viticulturists, oenologists and winemakers define several types maturity: technological, phenolic aromatic. Aromatic probably most important for determining wine typicity, including terroir expression. This article (part I) reviews state-of-the-art compounds underpinning aromatic maturity; influence fa...

Aromatic probably most important for determining wine typicity, including terroir expression. This article (part II) reviews influence factors management practices on aromatic maturity; latest kn...

Harvest maturity is closely related to peach fruit quality and has a very important effect on the fresh fruit market. Unfortunately, at present, it is difficult to determine the maturity level of peach fruits by artificial methods. The objectives of this study were to develop quadratic polynomial regression models using near-infrared spectroscopy that could determine the peel color difference, ...
