Miscanthus × giganteus is exceptional among C4 plants in its ability to acclimate to chilling (≤14 °C) and maintain a high photosynthetic capacity, in sharp contrast to maize, leading to very high productivity even in cool temperate climates. To identify the mechanisms that underlie this acclimation, RNA was isolated from M × giganteus leaves in chilling and nonchilling conditions and hybridize...

The effect of rapid chilling of pork carcasses on bacterial populations was examined. Two regimes of rapid chilling were applied: treatment 1 (at –31°C in the first 3 h of chilling, and then at 2–4°C till 8 h post-mortem) and treatment 2 (at –31°C in the first 3 h of chilling, and then at 2–4°C till 24 h post-mortem). Microbiological sampling of pork carcasses was obtained by swabbing. Swab sam...

in order to evaluate the effect of different mechanical treatments (application of sulphuric acid, boiling water and flooding) on seed dormancy breaking of licorice, an experiment was carried out in randomized complete block design in 2012. moreover, a factorial scheme in rcbd was performed to assess the application of giberalic acid and potassium nitrate treatment as well as stratification and...

The effects of chilling at 3 to 5 C on the nucleotide composition of roots and leaves of cotton (Gossypium hirsutum L.) seedlings were determined. Chilling decreased the concentration of nucleotides, especially di- and triphosphates, in both leaves and roots. Chilling also caused an increase in free nucleosides. The results are interpreted to mean that general phosphorolytic activity is associa...

the flowering phase of apple trees is the most critical step in relation with low temperatures and frost events. therefore, forecasting the time of flowering is important. if a model can predict the exact time of flowering, it would be feasible to care for flowers agianst late spring freezing (lsf). in this study, we evaluated three temperature-base chilling models namely: chilling hours (ch), ...

Quantifying below-ground carbon (C) allocation is particularly difficult as methods usually disturb the root-mycorrhizal-soil continuum. We reduced C allocation below ground of loblolly pine trees by: (1) physically girdling trees and (2) physiologically girdling pine trees by chilling the phloem. Chilling reduced cambium temperatures by approximately 18 degrees C. Both methods rapidly reduced ...

nowadays, in many rangelands, due to over grazing, and problems that some plantshave in germination, the rate of forage production is greatly reduced. so to take advantages ofthe benefits of such plants, it is necessary to identify and remove barriers of germination andestablishment of suitable plants. the present study was designed to investigate differenttreatments of breaking dormancy and st...

Mango, scientifically known as Mangifera indica L., is highly popular in Pakistan and around the globe for its abundant provitamins other phytochemical elements. Being a climacteric fruit, mangoes ripen quickly after being harvested. Commercial growers typically harvest when they reach their horticultural maturity to maintain fruit's quality. Temperature crucial environmental factor affecting m...

Commercial operations use low-temperature conditioning of citrus fruits to reduce the incidence of chilling injury (CI) during cold storage and quarantine treatments. Rio Red grapefruits (Citrus paradisi Macf) were stored for 12 weeks at 11°C or 5°C; an additional set was temperature conditioned at 16°C for 7 days before storing at 5°C (CD). Every 3 weeks, samples were assessed for chilling inj...
