The objective of this study was to evaluate the effect preharvest application 1-methylcyclopropene (1-MCP) on postharvest dissipation stress watercore incidence and severity rating over 30 d at 20 °C. ‘Jonagold’ trees were untreated or sprayed with 1-MCP one week before harvest. Harvest indices quality factors °C, assessed days 2, 5, 9,15, 20, 30. Fruit treated treatment had lower internal ethy...

disadvantages such as indeterminate inflorescence and high seed shattering during ripening are significant restrictions to introduce evening primrose as a commercial medicinal plant. following to the last works, a pot experiment was conducted to clarify the influence of defoliation before harvest on the seed yield, oil and gla (gamma-linolenic acid) percentage of evening primrose growing under ...

Background: AVG is an organic ethylene inhibitor. AVG treatments retarded the ripening process, increased fruit sizes and delayed loss of postharvest fruit flesh firmness by inhibiting ethylene. MeJA is a natural plant growth regulator and plays a regulatory role in various metabolic reactions. Apart from its role in fruit ripening, cell activities like anthocyanin and carotenoid synthesis and ...

We develop a continuum player unified timing game that also rationalizes sudden mass movements. Payoffs in the game are a logsubmodular function of time and the stopping quantile. Time captures the payoff-relevant fundamental — payoffs “ripen”, peak at a “harvest time”, and then “rot”. Capturing the strategic interaction, payoffs are single-peaked in the quantile. We distinguish between greed a...

A main challenge in harvest management is to set policies that maximize the probability that management goals are met. While the management cycle includes multiple sources of uncertainty, only some of these has received considerable attention. Currently, there is a large gap in our knowledge about implemention of harvest regulations, and to which extent indirect control methods such as harvest ...

This work aimed to (i) determine the reliability of a portable Bluetooth colourimeter for fruit colour measurements; (ii) characterise changes in quantitative skin attributes nectarine cultivar response time from harvest; and (iii) influence row orientation training system on colour. The measured with colourimeter, namely L*, a* b*, were calibrated validated against reference spectrophotometer....

Rice is harvested in the Mid-South at moisture contents (MCs) typically ranging from 13% to 22% (wet basis). Because these MCs are greater than those safe for long-term storage, rice is dried within a fairly short period after harvest to 12% to 13% MC before being placed in storage. Once dried, “processing” of rough rice into milled rice takes place throughout the year and consists of several o...

• The timing of N fertilization needs to consider the seasonal fluctuations in nitrogen (N) uptake. These could be summarized as followes: _ during the four weeks after budbreak : N is sourced from N stored in permanent structures, _ from 2 weeks before bloom to 4 weeks after bloom: there is a major N uptake by the roots, and _ after 4 weeks post-bloom: new peaks of N uptake happen at veraison ...

Abstract Applying fertilizer nitrogen (N) only when a crop response is predicted may enhance use efficiency and profitability while protecting the environment. The index at harvest (RI-harvest, ratio of maximum grain yield that plot in question) indicates actual to applied N, although it calculated after harvest. objective this study was predict RI-harvest wheat using normalized difference vege...
