Modeling the Budbreak in Peaches: A Basic Approach Using Chill and Heat Accumulation

Agronomy, 2023
Phenological shifts in peaches have been observed over the last few years due to the fluctuation of the seasonal climate conditions experienced during dormancy, affecting orchard management practices and influencing production and harvest dates.

Peach [Prunus persica (L.) Batsch] Cultivars Differ in Apparent Base Temperature and Growing Degree Hour Requirement for Floral Bud Break

Frontiers in Plant Science, 2022
Bud break timing in peach [Prunus persica (L.) Batsch] is determined by the sequential fulfillment of a chilling requirement (CR) and a heat requirement (HR) for development. Genotypic variation in CR has been well characterized in peach.

Persian Walnut (Juglans regia L.) Bud Dormancy Dynamics in Northern Patagonia, Argentina

Frontiers in Plant Science, 2022
Temperate deciduous fruit trees survive winter temperatures by entering a dormant phase in their aerial meristematic organs. Release from bud dormancy occurs after chill requirements (CR) have been satisfied, whereas bud burst/flowering follows heat ...

Impact of Chill and Heat Exposures under Diverse Climatic Conditions on Peach and Nectarine Flowering Phenology

Plants, 2023
The present study aims to generalize cultivar-specific tree phenology responses to winter and spring temperatures and assess the effectiveness of the Tabuenca test and various chill and heat accumulation models in predicting bloom dates for a wide range ...

Estimating Heat Requirement for Flowering in Peach Germplasm

Agronomy, 2022
Bloom date (BD) in peach is determined by the dynamic relationship between chilling (CR) and heat requirement (HR) fulfilment during dormancy. Understanding these thermal requirements would enable breeders to adapt new cultivars to variable climates ...

Heat requirement in an indoor recirculating aquaculture system

Energy Reports, 2022
Due to the benefits of the recirculating aquaculture system (RAS), many fish farmers are choosing this system. Some farmers chose indoor RAS, where fish tanks are kept inside buildings or greenhouses. Heating the buildings and the makeup water requires a

Thermal Analysis of Vertical Plate Fin Heat Sink [PDF]

E3S Web of Conferences, 2020
Heat Sinks are widely used to remove the heat from the components which are generating heat during their functioning. Overheating causes malfunctioning of the components as well as it is responsible for reducing their life. Free convection is very common
