應(yīng)用案例 2：
  水稻灌漿期的夜間高溫會顯著影響水稻的產(chǎn)量。捷克科學(xué)院研究中心與水稻研究所合作研究夜間高溫對成熟水稻穗光學(xué)特性的變化追蹤。研究者使用FluorPen手持式葉綠素?zé)晒鈨x測量了光合系統(tǒng)有效光化學(xué)效率ΦII（也稱為有效量子產(chǎn)額QY或ΦPSII）和穩(wěn)態(tài)熒光Fs。同時使用PolyPen手持式植物反射光譜測量儀的前期型號WinePen測量了反射光譜曲線，并計算了PRI、mSR705、mND705、R470/R570、R520/R675等9項植被指數(shù)。這些植被指數(shù)與水稻葉片/穗的光合能力、穩(wěn)態(tài)熒光、葉綠素濃度等緊密相關(guān)（Gil-Ortiz R et al. 2020）。
