Abstract

Providing quality planting materials is critical to sustainable forest restoration initiatives. This study aimed to analyze the tree seeding system and to evaluate and model the configuration of the tree seed supply system from the source to the growers. Primary and secondary data were collected in the Amhara region of Ethiopia. A total of 52 sample participants were selected using the snowball method and interviewed using open-ended questionnaires and Likert questionnaires. Data were analyzed using content and gap analysis methods using Atlas. ti version 8 software. The gap analysis revealed a lack of provenance trials, improved tree seeds, priority species in nurseries, and existing legislation. The model configuration was sequenced in tree seed source, procurement, and dissemination. Informal farmer suppliers covered 83 percent of the system. The decentralized-centralized-centralized and centralized-centralized-centralized were configured for the private enterprises and Amhara Forest Enterprise, respectively, as formal seed suppliers. In order to overcome the difficulties in tree seed production, those involved should work on the production of an improved tree.

埃塞俄比亚的林木种子供应系统：重点树种的来源和传播模式

提供优质的种植材料对于可持续森林恢复计划至关重要。本研究旨在分析树木播种系统，并对从源头到种植者的树木种子供应系统配置进行评估和建模。研究人员在埃塞俄比亚阿姆哈拉地区收集了第一手和第二手数据。采用滚雪球法选取了 52 名样本参与者，并使用开放式问卷和李克特问卷对其进行了访谈。使用 Atlas.ti 第 8 版软件，采用内容和差距分析方法对数据进行了分析。差距分析表明，缺乏原产地试验、改良树种、苗圃中的重点树种以及现有立法。在树种来源、采购和传播方面，对模型配置进行了排序。非正规农民供应商占整个系统的 83%。作为正规种子供应商的私营企业和阿姆哈拉森林企业分别配置了分散-集中-集中和集中-集中-集中模式。为了克服林木种子生产中的困难，相关人员应致力于改良林木的生产。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
