用途：PlantPen植物NDVI測量儀是一款設(shè)計精巧、可快速測量植物NDVI指數(shù)的便攜式儀器可根據(jù)反射系數(shù)確定植物特征，通過各種反射系數(shù)可以評定葉綠素含量。

        NDVI(歸一化植被指數(shù))是通過計算植物葉片對660 nm和740 nm兩種波長光發(fā)射情況計算得到的值，反應植物葉綠素含量的重要參數(shù)。一個方便的葉夾、簡單的兩鍵操作以及明亮的顯示屏使得PlantPen在不干擾調(diào)查植物（無葉片脫落或損壞）下仍方便使用。

        測量數(shù)據(jù)存儲于儀器內(nèi)部，可選擇藍牙（NDVI 300-B）或USB數(shù)據(jù)線（NDVI 300-U）與計算機連接，使用專業(yè)FluorPen軟件進行數(shù)據(jù)傳輸和可視化分析；可選配GPS模塊。

特點：

    設(shè)計緊湊、堅固的PRI非常適用于野外環(huán)境、植物溫室等

    *的手持葉夾，雙鍵操作，LED顯示屏設(shè)計，使用方便

    非侵入式無損測量

    4節(jié)AAA電池供電，方便耐用

    USB或藍牙傳輸數(shù)據(jù)，專業(yè)軟件進行可視化分析

應用：

    光合作用教學與研究

    植物分子生物學

    植物的篩選和實地研究

    逆境生理

    農(nóng)學與林業(yè)

        對于NDVI, Umbilicaria arctica和Umbilicaria hyperborea隨著水勢的變化有相同的變化趨勢，均隨著水勢降低而降低，但兩物種之間存在差異。*水化的U. arctica的NDVI在0.55-0.75之間，U. hyperborea的NDVI比較低，在0.30-0.55之間；脫水后的U. arctica在0.55-0.30之間，而U. hyperborea在0.30-0.15之間。
