The use of growth rings dimensional parameters has been an important tool for the understanding of growth, biomass allocation and climatic characterisation of forest species. However, its potential is unknown in perennial crops of socio-economic importance, such as coffee. This work aimed to understand how the analysis of the growth rings can be used as a proxy to understand the climatic determinants of vegetative growth and biomass allocation in the different organs of coffee trees. The work was carried out in the southern region of Minas Gerais, Brazil. The structure of the growth rings of cross sections of the orthotropic stem of coffee trees (Coffea arabica L. cv. Arara) were analysed from 2011 to 2018, using standard dendrochronological techniques. Each year in that period was characterised climatically and by its bienniality. Pearson correlation statistical analysis was used for mapping the relation among annual radial growth rates of the trees and other assessed parameters as primary growth data, accumulated biomass and the climatic characteristics of the region on an annual and intra-annual scale. During the study the water balance (conditioned by its components, Prec and ETo) and the maximum temperature were the main determinants of the characteristics of the formed ring and the plant biomass allocation. These growing characteristics were also influenced by the phenology that modulates the vegetative/reproductive growth cycles and in turn the biennial production cycles. The results show the potential of tree rings and dendrochronology as a tool that allows indirect, but long-term, assessment of biomass allocation and growth in coffee trees.

利用年轮面积作为生物量积累的预测因子及其对咖啡树生长的气候决定因素
使用年轮尺寸参数已成为了解森林物种的生长、生物量分配和气候特征的重要工具。然而，它在具有社会经济重要性的多年生作物（例如咖啡）中的潜力尚不清楚。这项工作旨在了解如何将年轮分析用作了解咖啡树不同器官营养生长和生物量分配的气候决定因素的代理。这项工作是在巴西米纳斯吉拉斯州南部地区进行的。咖啡树（Coffea arabica）正交异性茎横断面年轮结构L.简历。Arara) 于 2011 年至 2018 年间使用标准的树木年代学技术进行了分析。那个时期的每一年都以气候和两年一次为特征。Pearson 相关统计分析用于绘制树木的年径向增长率与其他评估参数之间的关系，作为初级生长数据、累积生物量和该地区在年度和年度范围内的气候特征。在研究过程中，水平衡（由其成分 Prec 和 ETo 调节）和最高温度是形成环的特征和植物生物量分配的主要决定因素。这些生长特征还受到调节营养/生殖生长周期以及两年一次生产周期的物候的影响。
