Abstract

Amaranthus palmeri S. Watson is a problematic weed that has been encountered almost all over the world because of its stronger adaptability, which causes huge economic losses and local plant diversity decline. As an invasive plant, A. palmeri has been found throughout China. We thus make a code system to describe the phenological growth process of A. palmeri according to the extended BBCH scale to better understand the phenological growth of this weed in China. The growth process of A. palmeri was divided into vegetative growth phases and reproductive growth phases. The vegetative growth phases are composed of seed germination (0), leaf development (1), formation of side shoots (2) and main stem elongation (3). Likewise, the reproductive growth phases include inflorescence emergence (5), blooming (6), fruit development (7), seed maturity (8) and senescence (9). Based on the extended BBCH scale, the first digit stands for the primary growth stages, and the third digit represents the secondary growth stages. In particular, the second digit defines the growth progress: the number 0, means the vegetative growth phases, and the number 1 stands for the reproductive growth phases. Owing to the fact that its seed can germinate multiple times within a year, a general illustration of the phenological development stages of A. palmeri germinating in different months was provided here to describe the growth dynamic characteristic at different times. These data are of great significance to develop effective strategies for weed control and management of A. palmeri.

根据扩展的 BBCH 尺度确定的棕榈苋的物候学生长阶段
棕榈苋(Amaranthus palmeri S. Watson)是一种问题杂草,由于其适应性较强,几乎在世界各地都有发现,造成了巨大的经济损失和当地植物多样性的减少。作为一种入侵植物,A. palmeri 在中国各地都有发现。因此,我们根据扩展的 BBCH 尺度建立了描述棕榈蓟草物候期生长过程的编码系统,以更好地了解这种杂草在中国的物候期生长情况。棕榈属杂草的生长过程分为无性生长期和生殖生长期。无性生长阶段包括种子萌发(0)、叶片发育(1)、侧枝形成(2)和主茎伸长(3)。同样,生殖生长阶段包括花序萌发(5)、开花(6)、果实发育(7)、种子成熟(8)和衰老(9)。根据扩展的 BBCH 标度,第一位数字代表初级生长阶段,第三位数字代表次级生长阶段。其中,第二位数字定义了生长进程:数字 0 代表无性生殖阶段,数字 1 代表生殖生长阶段。由于其种子可在一年内多次萌发,这里提供了棕榈蓟在不同月份萌发的物候发育阶段的一般图解,以描述不同时期的生长动态特征。这些数据对制定有效的棕榈属杂草控制和管理策略具有重要意义。

期刊介绍: Annals of Applied Biology is an international journal sponsored by the Association of Applied Biologists. The journal publishes original research papers on all aspects of applied research on crop production, crop protection and the cropping ecosystem. The journal is published both online and in six printed issues per year. Annals papers must contribute substantially to the advancement of knowledge and may, among others, encompass the scientific disciplines of: Agronomy Agrometeorology Agrienvironmental sciences Applied genomics Applied metabolomics Applied proteomics Biodiversity Biological control Climate change Crop ecology Entomology Genetic manipulation Molecular biology Mycology Nematology Pests Plant pathology Plant breeding & genetics Plant physiology Post harvest biology Soil science Statistics Virology Weed biology Annals also welcomes reviews of interest in these subject areas. Reviews should be critical surveys of the field and offer new insights. All papers are subject to peer review. Papers must usually contribute substantially to the advancement of knowledge in applied biology but short papers discussing techniques or substantiated results, and reviews of current knowledge of interest to applied biologists will be considered for publication. Papers or reviews must not be offered to any other journal for prior or simultaneous publication and normally average seven printed pages.
