The common bean, Phaseolus vulgaris L., is a legume of economic and food importance in tropical and subtropical countries. Thus, the objective of this study was to define the phenological growth stages of common beans according to the Bundesanstalt Bundessortenamt und Chemische Industrie (BBCH) scale, as well as the degree days, to optimise common bean management practices in accordance with the plant phenology. All phenological stages, including germination, foliar development, side shoots formation, stem elongation, inflorescence emergence, flowering, pod development and plant senescence, were evaluated using the BBCH scale. The descriptions of the phenological stages, combined with illustrations, and the sum of degree days during the crop cycle improve our understanding of these phenological stages. The identification of the vegetative and reproductive stages of the common bean facilitates improved management of the crop under different environmental conditions, taking thermal accumulation into consideration.

根据BBCH量表得出的菜豆生长期的热和和物候描述

普通豆，菜豆L.，是热带和亚热带国家中具有经济和食品重要性的豆类。因此，本研究的目的是根据Bundesanstalt Bundessortenamt und Chemische Industrie（BBCH）量表和度数天数来定义普通豆的物候生长阶段，并根据植物物候来优化普通豆的管理实践。使用BBCH量表评估了所有物候阶段，包括发芽，叶发育，侧枝形成，茎伸长，花序出苗，开花，荚果发育和植物衰老。对物候阶段的描述，再加上插图，以及作物周期中度数天数的总和，有助于我们更好地理解这些物候阶段。
