One of the most widespread methodologies used to describe phenological stages in plants was developed by the Biologische Bundesanstalt Bundessortenamt und Chemische Industrie (BBCH). The BBCH scale utilises a decimal‐code system that divides plant phenological stages into a binary code composed of the principal and the secondary stages. This system has been extensively used to describe the phenological stages of diverse species, but there is no phenological description that can aid researchers in defining the duration of phenological stages of annual Mediterranean forage legumes that present different growth habits. The development of a precise phenological scale for forages enables the determination of grazing management strategies to attain a desired forage yield and quality as to precisely define the timing of agronomical practices. We have adapted the BBCH decimal‐code scale for Medicago polymorpha, Trifolium alexandrinum, Trifolium subterraneum, and Vicia benghalensis. The scale consists of 10 main stages with specific secondary stages. Descriptive keys with illustrations will help identify any particular phenological stage for each species. The scales presented here will aid researchers and the agricultural community in clearly defining the timing of agronomical practices, such as the appropriate time for grazing/harvest of these species.

基于BBCH量表的地中海饲用豆类的物候期

用于描述植物物候阶段的最广泛的方法之一是由德国生物学和化学工业（BBCH）开发的。BBCH量表使用十进制代码系统，该系统将植物物候阶段划分为由主要阶段和次要阶段组成的二进制代码。该系统已被广泛用于描述不同物种的物候阶段，但是没有任何物候描述可以帮助研究人员确定表现出不同生长习性的一年生地中海饲用豆类植物物候阶段的持续时间。精确的草料物候量表的发展使得能够确定放牧管理策略，以达到所需的草料产量和质量，从而精确地确定农艺实践的时机。南苜蓿，三叶草alexandrinum，红车轴subterraneum和蚕豆火柴头。该量表由10个主要阶段组成，并具有特定的次要阶段。带有插图的描述性键将有助于识别每个物种的任何特定物候阶段。这里介绍的量表将帮助研究人员和农业界清楚地定义农艺实践的时间，例如放牧/收获这些物种的适当时间。
