Course Description	休眠（dormancy）在植物適應多變環境條件的過程中扮演關鍵角色。本 EMI 課程將深入探討園藝作物種子與芽體休眠的基本調控機制，並進一步介紹園藝產業中常用的技術與管理手段，用於人工促進休眠解除、提升作物生產的穩定性與效率。透過系統性的學習與整合，學生將能深入理解休眠的重要性，以及其在園藝生產上的實務意涵與應用價值。課程連結聯合國永續發展目標（SDGs），特別關注糧食安全（SDG 2）、氣候調適行動（SDG 13）與陸域生態保育（SDG 15），強化學生在農業永續領域的全球視野。 Dormancy plays a crucial role in plant adaptation to dynamic environmental conditions. In this EMI course, we will delve into the fundamental mechanisms governing seed and bud dormancy in horticultural crops. Additionally, we will explore the techniques employed by horticulturists to artificially induce dormancy release in crop production. Through a comprehensive examination of these topics, students will gain a deep understanding of the significance of dormancy and its practical implications in Horticulture.The course integrates key United Nations Sustainable Development Goals (SDGs), with a focus on SDG 2 (Zero Hunger), SDG 13 (Climate Action), and SDG 15 (Life on Land), fostering a broader understanding of sustainability in horticultural production.

Evaluation

評分方式與標
1. 個人口頭報告（30%）
個人口頭報告旨在讓學生在英語情境下培養公開演說能力，同時建立自信與表達自我（self-belief）。本課程為研究所層級，期待學生以接近科學研討會口頭報告的專業規格進行呈現。每位學生需進行 10 分鐘報告，包含：自我介紹（1 分鐘）、主體內容（7 分鐘）與問答（2 分鐘）。授課教師將依報告的內容品質、架構與邏輯、回應提問能*以及英文發音清晰度進行評分。語速與口音不作為主要評分重點，但將著重於整體呈現的專業度與表達效果。

2. 分組專題（口頭報告 20% + 書面報告 20% + 組內同儕互評 10%）
分組專題旨在促進合作學習與對指定「植物休眠」相關主題的深入討論。各組需於課外定期開會，規劃並推進專題內容。專題成果包含：
分組口頭報告（採團體共同成績）
書面報告：以 mini-review（小型綜述）形式撰寫
此外，每位組員需對同組成員的投入與貢獻進行**同儕互評**，包含給分與具建設性的回饋意見；此互評結果將納入期末總成績。

3. 作業（20%）
學期中需完成 2 次作業，每次10 分。作業形式可能包含與課程內容相關之期刊論文或推廣／延伸文章（extension articles）的摘要、整理或評論。作答時可參考個人筆記、課堂投影片及其他資料，但除非授課教師明確允許，原則上需獨立完成。作業可選擇以英文或中文作答。

Grading Criteria
1.Personal Oral Presentation (30%)
The oral presentation component aims to provide students with an opportunity to develop their public speaking skills in English while instilling confidence and self-belief. As this is a graduate-level course, the expectation is for students to deliver a professional presentation akin to those seen at scientific conferences. Each student will deliver a 10-minute oral presentation, comprising a brief self-promotion segment (1 min), main content (7 mins), and a Q&A session (2 mins). The instructor will assess the presentation based on factors such as content, structure, the ability to address questions, and English pronunciation. While speech speed and accent will not be the primary focus of evaluation, emphasis will be placed on the overall presentation quality.

2.Group project - Oral presentation (20%) + Written report (20%) + “Peer evaluation within the group (10%)
The group project is designed to foster collaboration and in-depth discussion on a designated topic related to plant dormancy. Each group will regularly meet outside of class to plan and develop their project. The project culminates in an oral presentation, which will be graded collectively. The group will also submit a mini-review as their written report. Additionally, each member will be required to evaluate the contributions of their peers by providing a grade and constructive feedback on individual performance. This peer evaluation will contribute to the final grade.

3.Assignments (20%)
Throughout the semester, students will be required to complete two assignments, each worth 10 points. The assignments may involve tasks such as summarizing or reviewing journal papers and extension articles related to the course material. While students are allowed to refer to their personal notes, slides, and other reference materials, it is important to complete all assignments independently unless the instructor explicitly permits collaboration. Students have the option to answer the assignments in either English or Chinese.
