It also decreased the photochemical efficiency (Δ F / Fm ′) of PS II under actinic light, electron transport rate ( ETR ) and ATP content per unit leaf area but increased the intercellular CO 2 concentration and non photochemical quenching of chlorophyll fluorescence ( NPQ ). 同时,光系统Ⅱ光化学效率(ΔF/Fm′)、电子传递速率(ETR)和单位叶面积ATP含量均降低,而胞间二氧化碳浓度(Ci)和叶绿素荧光非光化学猝灭(NPQ)增加。
Non photochemical Quenching of Chlorophyll Fluorescence in Soybean and Sweet Viburnum Leaves 珊瑚树和大豆叶片叶绿素荧光的非光化学猝灭
Furthermore, ALA treatment led to both the increase of photochemical fluorescence quenching and non photochemical fluorescence quenching, where the former increased the leaf photochemistry rate, and the latter was associated with the increased energy dissipation via thermal in the antenna and the thermal dissipation rate. ALA具有促进叶绿素荧光光化学猝灭和非光化学猝灭的双重特性,其中,前者提高了叶片光化学速率,后者增加热耗散量以及提高热耗散速率。
In order to observe the responses of non photochemical chlorophyll fluorescence quenching ( qN ) as well as the change courses and components of qN to drought and shade stresses, these parameters were measured in different treatments. 为了了解玉米叶绿素非光化学荧光猝灭(qN)对干旱和遮光逆境的反应,我们研究了qN的主要叶绿素荧光参数。
