TL;DR: Reducing the rate of fruit transpiration during the first week of storage by a pre-cooling treatment prior to low-temperature storage delayed, but did not eliminate, the development of chilling injury.

TL;DR: The central roles of membranes and calcium in maintaining quality are discussed and the need to reduce respiration to maintain the “energized state” is discussed.
Abstract: The physiological consequences of minimal processing are dire. Mechanical injury sets off a complex series of events which result in loss of quality (i.e. color, texture and flavor). Control of this wounding response is a major obstacle that must be overcome. To prolong postharvest life, respiration must be reduced while producing enough energy to maintain the “energized state”. The central roles of membranes and calcium in maintaining quality are discussed.

TL;DR: In this article, the impact on postharvest responses, of pre-harvest exposure of fruit and vegetables to direct sunlight, with associated high tissue temperatures, is reviewed, including the role of heat shock proteins, membrane damage, and skin characteristics.

TL;DR: In this article, commercially ripe "Fortune" mandarins were dipped in water at 50 °C (Dip50), 52 °C(Dip52), 54 °C-(Dip54), 56 °C ("Dip56") or 58 °C "Dip58") for 3 min before storage at 6 °C for 30 days and 3 additional days at 20 °C.

TL;DR: The various quality aspects of chilling injury serve as the focus of this review in which symptoms, occurrence and its alleviation are discussed.
Abstract: The various quality aspects of chilling injury (CI) serve as the focus of this review in which symptoms, occurrence and its alleviation are discussed. CI is a term used to describe the physiological damage that occurs in many plants and plant products, particularly those of tropical and subtropical origin, as a result of their exposure to low but nonfreezing temperatures. The substantial economic consequences of CI have provided the impetus for studying/developing effective means of alleviating symptoms which manifest this disorder. A diversity in plant responses to low temperature stress exists, including alterations in ethylene biosynthesis, increased respiration rates, cessation of protoplasmic streaming, increased solute leakage, and uncoupling of oxidative phosphorylation. These various responses ultimately give rise to an array of visual symptoms (e.g., surface pitting, water rot, poor color development, general loss of structural integrity) which can render severe losses in product quality both pre- and postharvest. A number of different methods are available by which to alleviate symptom development, including manipulation of storage conditions (e.g., temperature cycling, hypobaric and modified atmosphere storage), exogenous chemical treatments (e.g., application of phospholipids, antioxidants, calcium) and genetic modification of chill sensitive species. These are discussed with respect to their effectiveness and possible control mechanisms.

TL;DR: The potential of hot water dipping (HWD) for 3min at 50°C and hot air treatment (HAT) at 37°C for 48h to control chilling injury and decay in "Tarocco" and "Moro" blood oranges during cold quarantine at 1/16 days, subsequent storage at 8/C for 3 weeks and an additional week of simulated marketing period (SMP) at 20/°C was investigated over 2 years' harvest seasons.

TL;DR: The amount of wax/cm2 on expanding primary leaves of bonus barley depends on both the photo-and thermoperiods in which the seedlings are grown as mentioned in this paper, which demonstrates that wax synthesis and extrusion is not directly correlated with leaf expansion.

TL;DR: Seedlings of tomato (Lycopersicon esculentum, Mill.) varied diurnally in their sensitivity to chilling temperatures, and six other chilling-sensitive species showed similar diurnal changes in their chilling sensitivity.
Abstract: Seedlings of tomato (Lycopersicon esculentum, Mill.) varied diurnally in their sensitivity to chilling temperatures. If chilled near the end of the dark period when they were most sensitive, the time taken to kill half of the seedlings was approximately 3 days, whereas in samples taken 4 hours after the onset of dark, a period of 6 days of chilling was required. Sensitivity dropped rapidly after the onset of the light period. This rhythm was exogenously controlled by the diurnal changes in light, rather than in the temperature. The susceptibility of predawn seedlings could be reduced by exposure to light, by water stress, or by abscisic acid applied to the leaves. However, the subsequent changes in sensitivity to chilling did not correlate with stomatal aperture. Six other chilling-sensitive species showed similar diurnal changes in their chilling sensitivity.

TL;DR: The distribution of citrus rust mite on individual fruit and in the whole citrus tree suggests an avoidance of solar exposure, and the north bottom quadrant had the most favorable temperatures and usually the most rust mites; the south bottom was also favorable and had high mite densities.
