中文摘要 | 本研究以紅外線熱像技術,評估樟樹(Cinnamomum camphora (L.) Presl)葉片受樟樹木蝨Trioza camphorae Sasaki及樟白介殼蟲Aulacaspis yabunikkei Kuwana吸食後之溫度變異。結果顯示樟樹葉片溫度,在早上(27.6℃)、中午(36.6℃)、晚上(29.5℃)之日周期時序上,有顯著性差異(F=2152, p=0.0001),表示樟樹葉片溫度顯著受不同時段的環境氣溫影響。樟樹之健全葉片,在葉基、葉中、葉尖及葉緣兩側,5個不同部位測得紅外線熱像平均溫度在31.1℃-31.4℃,差異性不顯著。受昆蟲吸食葉片無論是損害部位或未損害部位平均葉片溫度分別爲28.2及28.0℃,皆高於健全葉片之27.9℃。樟樹健全葉片的葉面及葉背,兩者間無顯著性差異。在24小時連續監測結果中顯示,健全及受昆蟲吸食葉片之紅外線熱像檢測溫度,皆顯著受到氣溫及相對濕度的影響;當溫度、相對濕度變化較爲穩定時,可測得受昆蟲吸食葉片溫度顯著高於健全葉片約0.2℃(α=0.05 p value<0.001)。本試驗發現,健全葉片溫度、受昆蟲吸食葉片溫度及氣溫,三者之間具有顯著性直線正相關(r^2=0.97-0.99)。本試驗結果可提供作爲紅外線熱像技術檢測及評估苗木健康性管理應用的基礎。 |
英文摘要 | Infrared thermal imaging techniques are applied to indicate surface temperature of plants. In this study, we observed the temperature of solid leaf and phytophagy (Trioza camphorae and Aulacaspis yabunikkei) sucked leaf of camphor tree (Cinnamomum camphora) by infrared thermal imaging techniques. Significant differences in the solid leaf temperature of camphor tree were observed in morning (27.6℃), noon (36.6℃), and night (29.5℃) by one way ANOVA and Tukey test. Moreover, there were no significant differences in the leaf temperature at different leaf positions (base, center, apex, side) by ANOVA. The phytophagy sucked leaf (damaged and undamaged) temperatures were higher (28.2 and 28.0℃) than solid leaf temperature (27.9℃) of sampled trees by ANOVA and Tukey test. There was no significant difference in the leaf temperature between leaf upper surface and lower positions by t-test. When air temperature and relative humidity were steady, the sucked leaf temperatures were higher than solid leaf temperature from the measurements of infrared thermal imaging during 24-hr. Correlations between the solid leaf, sucked leaf, and air temperatures could be represented by positive linear regression formulas. Also, the leaf temperature was significantly influenced by air temperature and relative humidity. These results can provide practical application for tree or seedling health evaluation and management by infrared thermal imaging. |
