中文摘要 | 樟樹、茄苳.台灣欒樹、光蠟樹和鐵冬青等生長於經氫氧化銅處理的750 ml 體積塑膠袋與穴植管容器中6 mo,測試及評估各種生長性狀,以瞭解氫氧化鋼處理之容器 苗的生長效應。生長於銅處理的塑膠袋或穴植管苗木未發現葉部有銅毒害症狀。比較未經 銅處理的對照組,銅處理的容器苗顯著地減少根球表面根群的覆蓋度,並減短苗木的最長 根長度,但是除台灣欒樹塑膠袋苗的根乾重、茄苳穴植管苗的莖根比外,其餘樹種之根乾 重和莖恨比與對照組相比較皆不顯著。其他生長性狀如苗高、地徑和莖棄乾重等,因樹種 不同其處理間偶有不同的差異。例如台灣欒樹之苗高、地徑和莖葉乾重在銅處理的容器中 有顯著的增加;鐵冬青之苗高、地徑和莖乾重在銅處理的穴植管有顯著效果,但在塑膠袋 則否;光蠟樹之苗高只在銅處理的塑膠袋有顯著較高的生長,而樟樹和茄苳之苗高無論在 塑膠袋或穴值管,其處理間皆無顯著差異。結論是此五種樹苗在銅處理的育苗容器中生長 6 mo。不會產生盤根現象,且銅處理之塑膠袋和穴植管苗有相似的生長表現。 |
英文摘要 | Seedlings of Cinnamomum camphora, Bischofia javanica, Koelreuteria henryi, Fraxinus formosana, and llex rotunda were grown in 750-mL polyethylene bags and dibbling tubes for 6 months both with and without cupric hydroxide-treated interior surfaces. Seedlings were evaluated for shoot and root growth. NO foliar copper toxicity symptoms were observed on any species during the study. In comparison with untreated containers, copper-treated containers significantly decreased root coverage on the exterior of the rootball and the length of the longest root for all 5 species. Root dry weight and the shoot-to-root ratio were not significantly affected by copper-treated containers of these species except for the root dry weight of K. henryi in polybags and the shoot-to-root ratio of B. javanica in tubes. Differences in seedling height, basal diameter, and leaf and stem dry weights depended on whether the species were grown in either polybags or tubes. For example, significant increases in seedling height, basal diameter, and leaf and stem dry weights were measured in K. henryi grown in cupric hydroxide-treated containers; the same significant responses were found in tubes but not in polybags of I. Rotunda. F. formosana seedlings grew faster in height when grown in treated polybags only. There were no differences in seedling height of C. camphora and B. javanica in polybags or tubes. In conclusion, copper-treated containers eliminated root circling and deformation in these 5 species, and seedlings in treated polybags and tubes exhibited similar growth results. |
