The various degrees of preharvest sprouting occurring in hybrid rice is a limiting factor in the propagation and production of hybrid rice seeds. The phenotype of sprouted rice is very similar to that of the maize (Zea mays) seed-specific mutation viviparous 1. VP1 has been shown to be a transcription factor essential for seed maturation and dormancy induction. In this study, numerous truncated...

Produce-related outbreaks have been traced back to the preharvest environment. A longitudinal study was conducted on five farms in New York State to characterize the prevalence, persistence, and diversity of food-borne pathogens in fresh produce fields and to determine landscape and meteorological factors that predict their presence. Produce fields were sampled four times per year for 2 years. ...

Mango, a tropical fruit of great economic importance, is generally harvested green and then commercialised after a period of storage. Unfortunately, the final quality of mango batches is highly heterogeneous, in fruit size as well as in gustatory quality and postharvest behaviour. A large amount of knowledge has been gathered on the effects of the maturity stage at harvest and postharvest condi...

Preharvest conditions, including photoperiod and irrigation regime, affect the keeping quality of long stem roses (Rosa x hybrida). Rose plants cultivar ‘Charming Black’ were subjected to four different treatments investigate how nocturnal supplemental lighting regimes influence post-harvest performance. Vase life, ornamental quality, water balance, petal color, vacuolar pH, soluble sugar conte...

Worldwide depletion of fish stocks has led fisheries managers to become increasingly concerned about rebuilding and recovery planning. To succeed, factors affecting recovery dynamics need to be understood, including the role of fisheries-induced evolution. Here we investigate a stock's response to fishing followed by a harvest moratorium by analyzing an individual-based evolutionary model param...

Pulmonary edema is common in organ donors and lung transplant recipients. Therefore, we assessed the responsiveness of human donor lungs to pharmacological agents that stimulate clearance of alveolar edema. Organ donors whose lungs were rejected for transplantation were studied. After resection, transport (4 degrees C), and rewarming (37 degrees C) of lungs, alveolar fluid clearance was measure...

This study investigated the occurrence of resveratrol in Fragaria x ananassa Duchesne and the effect of preharvest conditions on resveratrol content. Both cis- and trans-resveratrol were detected in strawberry achenes (seeds) and pulp (receptacle tissue). Resveratrol was found to be higher in achenes than in fruit pulp. The levels of resveratrol were affected by genotype variations, fruit matur...

The Chilean strawberry (Fragaria chiloensis) fruit has interesting organoleptic properties, but its postharvest life is affected by gray mold decay caused by Botrytis cinerea. The effect of preharvest applications of methyl jasmonate (MeJA) or chitosan on the molecular defense-related responses and protection against gray mold decay were investigated in Chilean strawberry fruit during postharve...

Abstract The objective of this study was to assess the effects post-bloom (PB) or preharvest (PH) treatments ‘Braeburn’ apple trees with prohexadione-calcium (ProCa; 300 mg L-1), an inhibitor gibberellins biosynthesis, GA4+7 (300 L-1) on fruit quality at harvest and after storage (four months 0±0.5 oC, followed by five days shelf life). PB started 15 full bloom, one application every week six a...
