摘要

本研究旨在瞭解華林生態園區土肉桂營養系林木之香甜辣情形並予以分級，期建立相關資料庫以利日後進行相關試驗研究與利用。華林生態園區土肉桂營養系林木為中國文化大學故前森林學系(現更名為森林暨自然保育學系)系主任胡大維先生於台灣全省經多年收集近130株營養系在民國71～73年間扦插繁殖於本園區，然相關營養系林木資訊隨其過世而付之闕如，亟待重新建立。本研究於土肉桂營養系林地A區內逢機選取樣木19株採取葉片進行初探試驗。為避免個人主觀判斷，每株林木由7位工作人員分別測試7片葉片的香甜辣特性。每株林木至少需有4位工作人員認可並且每位工作人員至少辨識出4片葉片是否具有香甜辣特性，此株林木方可判定是否具有香甜辣之特性。研究結果顯示：所調查之土肉桂樣木19株，在株數方面，不香者(9株)略少於香者(10株)，不甜者(15株)顯著多於甜者(4株)，並且皆不具辣味特性；不香者皆不甜；香又甜、香但不甜、不香又不甜等林木特性分級之株數依序為4、6與9，株數比率依序為21.05%、31.58%與47.37%，卡方值4.5600，其發生機率值為0.0327，顯示各特性林木在株數間呈顯著差異；與不香之林木相比較，香者樹高有稍高而胸徑有稍細之趨勢，但主幹數與主幹分叉比率顯著較小；與不甜之林木相比較，甜者樹高顯著較矮而胸徑顯著較細，但主幹數與主幹分叉比率呈現較小之趨勢；香但不甜等級之林木樹高顯著較高、胸徑較粗而主幹數與主幹分叉比率呈現較小之趨勢，香又甜者則樹較矮且胸徑較細，不香又不甜者則主幹數與主幹分叉比率呈現較大之趨勢。故可運用此林木香甜辣分級方式於華林生態園區土肉桂營養系林木，建立資料庫。

This study wanted to classify aroma-sweetness-spicy characteristics of Cinnamomum osmophloeum Kanehiraclonal trees at Hwa-Lin Ecological Garden. Mr. Da-Wei Hu, ex-chairman of Forestry Department, Chinese Culture University, collected 130 trees overall Taiwan by cutting method during years of 1982~1984. However, their basic information was lost as he passed away. Related data bank needs to be re-established. This preliminary study used 19 randomly selected clonal trees from C. osmophloeumKanehira plantation zone A at Hwa-Lin Ecological Garden. To avoid personally subjective judgment, each tree was tested by 7 staff members, and each staff member used 7 leaves to classify aroma-sweetness-spicy characteristics of each tree. A tree was classified as specific characteristic by at least 4 staff members and at least 4 leaves with specific characteristic by each staff member. The results showed: 1) From number of tree, 9 non-aroma trees were a little lesser than 10 aroma ones; 15 non-sweet trees was significant more than 4 sweet ones; and no spicy tree was found. 2) No. (and ratio)of aroma-sweet, aroma-non-sweet, and non-aroma-non-sweet tree were 4 (21.05%), 6 (31.58%) and 9 (47.37%), respectively. Chi-square value (X^2) was 4.5600 and its probability was 0.0327. Significant differences were found among those characteristic classifications. 3) Aroma trees showed tendency of taller height with smaller DBH but significant lower main stem No. and forked ratio than non-aroma ones; sweet trees showed significant shorter height and smaller DBH but tendency of smaller main stem No. and forked ratio than non-sweet ones. Aroma-non-sweet trees were very significantly tallest in height and larger DBH, and showed tendency of lower main stem No. and forked ratio; aroma-sweet trees shorter height and smaller DBH, non-aroma-non-sweet trees tendency of larger main stem No. and larger forked ratio. Therefore, aroma-sweetness-spicy characteristic classification can be used to establish related data bank of C. osmophloeumKanehiraclonal trees at Hwa-Lin Ecological Garden.
