Abstract Climate strongly determines the growing range of fruit plant species that can be grown successfully in an area, and also the cultivars that will perform best. Therefore, the assessment of the adequacy of a climate is critical for decision-making in the design of fruit orchards and vineyards, and also for the evaluation of the potential consequences of future climate on fruit production. Bioclimatic indices and plant phenology models are commonly used to assess the suitability of climate for growing quality fruit and to provide temporal and spatial information about regarding ongoing and future changes. In this paper, we present fruclimadapt, a flexible and versatile package in the R language that streamlines the assessment of climate adaptation and the identification of potential risks for grapevines and fruit trees. A core set of functions allows to assess climate adaptation of fruit tree species by calculating specific bioclimatic index values and to evaluate potential threats to yield and fruit quality. Three additional sets of functions have been included as companions to: i) downscale daily meteorological values to hourly data, ii) estimate winter chill and forcing heat accumulation and iii) estimate the occurrence of phenological phases. fruclimadapt is currently available from the CRAN website ( https://cran.r-project.org/package=fruclimadapt ).

fruclimadapt：用于温带水果物种气候适应评估的 R 包

摘要 气候在很大程度上决定了一个地区可以成功种植的水果植物物种的生长范围，以及表现最好的品种。因此，气候适宜性的评估对于果园和葡萄园的设计决策以及评估未来气候对水果生产的潜在影响至关重要。生物气候指数和植物物候模型通常用于评估气候是否适合种植优质水果，并提供有关当前和未来变化的时空信息。在本文中，我们介绍了 fruclimadapt，这是一种灵活且通用的 R 语言包，可简化气候适应评估以及葡萄藤和果树潜在风险的识别。一组核心功能允许通过计算特定的生物气候指数值来评估果树物种的气候适应性，并评估对产量和果实质量的潜在威胁。还包括了三组额外的功能，作为配套功能：i) 将每日气象值缩小到每小时数据，ii) 估计冬季寒冷和强迫热量积累，以及 iii) 估计物候阶段的发生。fruclimadapt 目前可从 CRAN 网站 (https://cran.r-project.org/package=fruclimadapt) 获得。ii) 估计冬季寒冷和强迫热量积累和 iii) 估计物候阶段的发生。fruclimadapt 目前可从 CRAN 网站 (https://cran.r-project.org/package=fruclimadapt) 获得。ii) 估计冬季寒冷和强迫热量积累和 iii) 估计物候阶段的发生。fruclimadapt 目前可从 CRAN 网站 (https://cran.r-project.org/package=fruclimadapt) 获得。
