1. Chilling requirement of four peach cultivars estimated by changes in flower bud weights
ABSTRACT The adaptation of temperate fruit crops is a challenge being increased by the global warming. Chilling requirement is a key factor for adaptation. The objective of this study was to estimate the chilling requirement of peach cultivars BRS Bonão, Esmeralda, Granada and Eragil, using the Tabuenca test. Chilling accumulation was computed using four di

2. Effects of thermal treatments on chilling injury and shelf life time of Citrus reticulata Blanco1
RESUMO A tangerina ‘Arrayana’ (Citrus reticulata Blanco) é considerada a variedade mais cultivada na Colômbia. Apesar de ser uma fruta não climatérica, apresenta curta vida pós-colheita. Para avaliar os efeitos do tratamento térmico na injúria por frio e na vida útil dessa cultivar, frutos maduros foram selecionados e submetidos aos seguintes tra

3. Delayed carcass chilling improves tenderness of the beef gluteus medius muscle
Resumo: O objetivo deste trabalho foi avaliar os efeitos de uma taxa de resfriamento mais lenta sobre as características físico-químicas da alcatra (M. gluteus medius) de touros F1 Angus x Nelore, maturada por 14 dias. Carcaças leves e magras (n = 30) foram divididas em meias carcaças e selecionadas para controle (2°C por 24 horas) e tratamento (10°C

4. EXPERIMENTAL APPROACH TO ASSESS EVAPORATIVE COOLING UNDER FORCED AIR FLOW
Abstract Air blast is one of the most employed industrial chilling methods. It can be enhanced, i.e., increasing heat transfer and reducing cooling time, by superficial evaporative phenomena. This work reports a methodology, including experimental setup and mathematical modelling, to quantify the air chilling enhancement by wetting the surface of the object

5. Effect of Process Parameters on the Microstructure of Semi-solid ZL101 Aluminum Alloy
Aluminum alloy is the important alloy which has been widely used. To reduce waste, it is necessary to thixoform these alloys in near net shape. Semi-solid slurry is the key in process. In this work, the semi-solid slurry of ZL101 aluminum alloy was prepared by using serpentine channel. Effect of process parameters on the microstructure of semi-solid ZL101 al

6. Effects of chemical treatments and environmental factors on seed dormancy and germination of shepherd's purse (Capsella bursa-pastoris (L.) Medic.)
Shepherd's purse (Capsella bursa-pastoris) is a problematic weed in citrus orchards and crop fields in northern Iran. In a series of laboratory and greenhouse experiments, we evaluated the effects that treatment with gibberellic acid (GA3) and potassium nitrate (KNO3), as well as environmental factors, including temperature, the duration of pre-chilling (wet

7. Quality of pitaya fruit (Hylocereus undatus) as influenced by storage temperature and packaging
Pitaya (Hylocereus undatus) is an exotic non-climacteric fruit that reaches its best eating quality when harvested ripe, decreasing thereafter during storage. Our objectives were to determine the best combination of storage temperature and use of perforated plastic bags to maintain the postharvest quality of the fruit. Fruits were stored at 5, 7, or 10 ºC w

8. Rootstocks induce contrasting photosynthetic responses of orange plants to low night temperature without affecting the antioxidant metabolism
Low temperatures negatively impact the metabolism of orange trees, and the extent of damage can be influenced by the rootstock. We evaluated the effects of low nocturnal temperatures on Valencia orange scions grafted on Rangpur lime or Swingle citrumelo rootstocks. We exposed six-month-old plants to night temperatures of 20ºC and 8ºC under controlled condi

9. Beef quality traits of Nellore, F1 Simmental × Nellore and F1 Angus × Nellore steers fed at the maintenance level or ad libitum with two concentrate levels in the diet
This trial was conducted to evaluate some beef quality attributes of Nellore, F1 Simmental × Nellore and F1 Angus × Nellore steers finished on feedlot. The effects of feeding regime and genetic group on shear force, thawing losses, cooking (leak + evaporation) losses, total losses and muscle fiber type, as well as carcass pH and temperature during 24 h of

10. Bioactive compounds and antioxidant capacities in the flavedo tissue of two citrus cultivars under low temperature
Antioxidants production is amongst the physiological responses of plants to protect their tissues from oxidative damages caused by chilling and freezing stresses. Indeed, cold tolerance of plants is related to production of reactive oxygen species (ROS) scavengers to combat oxidative stress. In this study, two citrus cultivars including Citrus sinensis 'Siav

11. Padrões climáticos atuais e futuros de temperatura do ar na Região Sul do Brasil e seus impactos nos cultivos de pêssego e de nectarina em Santa Catarina / Current and future air temperature climatic patterns in the South Region of Brazil: the impacts on peach and nectarine production in Santa Catarina
Over the years, climate changes and their direct impacts were observed in different parts of the globe. The present study considers the main air temperature patterns, including their extreme values, in Southern Brazil and assesses their impacts on peach and nectarine production. The analysis is based on daily air temperatures recorded at weather stations dis

12. Seleção de pessegueiro com base na necessidade de frio da semente e qualidade do fruto / Peach selection based on the seed chilling requirement and fruit quality
The peach [Prunus persica (L.) Batsch] is a temperate species that can be grown in areas with mild winter climates by the use of adapted genotypes. This species have dormant buds and seeds, and the exposure to low temperatures is the main way to overcome dormancy in these two organs. Generally, plants that have low chilling requirement to overcome dormancy o
