panicle

“panicle”是一個英語名詞，發音為英['pænɪkl]、美['pænɪkəl]，中文釋義為“圓錐花序”或“穗”。其形容詞形式為“panicled”。在植物學中，該詞專指複合總狀花序或分枝的花簇，常見於禾本科植物（如水稻）及某些花卉（如繡球花）的描述。詞典例句表明，panicle的套用涵蓋農業操作、形態分析及產量評估等領域。根據2025年的資料，該詞在愛詞霸線上詞典中未被收錄，但例句可見於劍橋英語語料庫。

釋義與詞性

“panicle”作為名詞，指植物學術語中的“圓錐花序”，即一種複合總狀花序或分枝的花簇結構。其形容詞形式“panicled”用以描述具有此類花序的植物。近義詞“raceme”指單一總狀花序，但與之相比，panicle的分支結構更為複雜。

詞源

該詞源自拉丁語“pānicula”（植物上的簇），後者為“pānus”（小米穗、線軸）的小型化形式，最終可追溯至多利安希臘語“pânos”（網）。

用法與例句

1. 農業操作：收割前panicle的田間存放時間直接影響脫粒效率（2023年例句）。
2. 形態描述：西班牙草本植物的羽毛狀圓錐花序與北美黍屬禾草的毛刷狀panicle形成鮮明對比（2021年例句）。
3. 產量評估：截至2023年，研究發現圓錐花序數量與糧食產量呈正相關。
4. 植物學研究：黃木的鬆散分枝花簇被視為典型的panicle結構（2023年例句）。

相關研究

2022年的研究表明，水稻穗重受劍葉光合特性、氣候生態及插秧量等因素顯著影響。不同穗重型水稻品種的外觀品質在濕熱與乾涼地區存在差異，根系性狀亦與穗重構成因子密切相關。
