ABSTRACT

The wild dioecious plant Corema album, endemic to the Atlantic coast of the Iberian Peninsula, has potential to become a new crop and to integrate the berry fruit market. Due to its potential, the aim of this study was to propose a BBCH (Biologische Bundesanstalt, Bundessortenamt and CHemical Industry) scale for the species. Based on field observation, the principal growth stages were described and sequentially established. Photographs and stereomicroscope acquisition software were used to illustrate the phenological stages of male and female plants.

The scale includes seven principal stages starting with bud development (stage 0), followed by leaf development (Stage 1), main stem elongation (Stage 3), inflorescence emergence (Stage 5), flowering (Stage 6), fruit development (Stage 7) and ending with fruit maturation (stage 8), with mesostages for male and female inflorescence (stage 5) and flower development (stage 6). Through field observations carried out in plants in different growth conditions, the proposition of this extended BBCH scale was made, to have a standardized system for Corema album phenological stages. This study will have an application especially in fields of agronomy and plant breeding and will also be a stepping stone for the inclusion of this species as a novelty crop in a nearby future.

摘要

伊比利亚半岛大西洋沿岸特有的野生雌雄异株植物Corema album，具有成为新作物并整合浆果市场的潜力。由于其潜力，本研究的目的是为该物种提出一个 BBCH（Biologische Bundesanstalt、Bundessortenamt 和化学工业）规模。根据现场观察，描述并依次确定主要生长阶段。使用照片和立体显微镜采集软件来说明雄性和雌性植物的物候阶段。

该量表包括七个主要阶段，从芽发育（第 0 阶段）开始，然后是叶片发育（第 1 阶段）、主茎伸长（第 3 阶段）、花序出现（第 5 阶段）、开花（第 6 阶段）、果实发育（第 7 阶段） ) 并以果实成熟（第 8 阶段）结束，雄性和雌性花序的中间阶段（第 5 阶段）和花发育（第 6 阶段）。通过对不同生长条件下植物的实地观察，提出了扩展BBCH规模的提议，以建立Corema专辑物候阶段的标准化体系。这项研究将特别适用于农学和植物育种领域，也将成为在不久的将来将该物种纳入新作物的垫脚石。
