Necesidades agroclimáticas (frío y calor) de variedades frutales [Conjunto de datos].https://hdl.handle.net/10532/7979[EN] This dataset compiles the agroclimatic requirements of 143 cultivars of five temperate fruit tree species: almonds (20) (1–3), apricot (42) (4,5) , Japanese plum (21) (6,7), pear (20) (8,9), and sweet cherry (47) (10–12). The results have been published in scientific journals and at Spanish national and international congresses (DOIs are indicated in the readme file) Dormancy Release dates were determined using statistical and/or empirical methods. The statistical analysis relied on the relationship between long-term flowering date records (approximately 20 years) and daily temperature data from the preceding eight months (13). These analyses were performed using either the “Correlation method” (14) or the Partial Least Square (PLS) regression analysis (15). The empirical methods include the traditional shoot forcing experiments, in which the buds’ ability to resume growth is evaluated after exposure to controlled growth chamber conditions (6). In addition, for apricot, a new method based on the timing of male meiosis has been validated as a dormancy biomarker (4). At least two years of experimental data are provided for each empirical method. The chilling period is defined as the time up to dormancy release, during which chilling temperatures are accumulated. Chill requirements are provided according to the most commonly used horticultural models: the Chill Hours Model (CH) (16), the Utah Model (Chill Units, CU) (17), and the Dynamic Model (Chill Portions, CP) (18). The heat period is defined as the time from dormancy release to flowering. Heat requirements are estimated using the Growing Degree Hours (GDH) model (19).[ES] Este conjunto de datos recopila las necesidades agroclimáticas de 143 cultivares de cinco especies frutales de clima templado: almendro (20), albaricoquero (42), ciruelo japonés (21), peral (20) y cerezo dulce (10–12).
