Abstract

Drought-related die-off events have been observed throughout Europe in Scots pine (Pinus sylvestris L.). Such events are exacerbated by carbon starvation that is, an imbalance of photosynthetic productivity and resource usage. Recent evidence suggests that optically measurable photosynthetic pigments such as chlorophylls and carotenoids respond to water stress (WS). However, there is a lack of measurements using imaging spectroscopy, and the mechanisms linking xanthophyll-related changes in reflectance captured by the photochemical reflectance index (PRI) and chlorophyll changes in red edge position (REP) to WS are not understood. To probe this, we conducted a greenhouse experiment where 3-year-old Pinus sylvestris saplings were subjected to water limitation and followed using hyperspectral imaging (HSI) spectroscopy, water status and photosynthetic measurements. Carotenoids (e.g., xanthophyll cycle) and chlorophylls responded to WS, which was observed using the HSI-derived indices PRI and REP respectively. The spatial-temporal response in these two pigment-reflectance groupings differed. The spatial distribution of PRI represented the light intensity around the time of the measurement, whereas REP reflected the daily averaged light intensity over the experimental course. A further difference was noted upon rewatering, where the carotenoid-related PRI partially recovered but the chlorophyll-related REP did not.

摘要

在欧洲各地的苏格兰松（Pinus sylvestris L.）中都观察到了与干旱相关的死亡事件。碳饥饿加剧了此类事件，即光合生产力与资源利用的不平衡。最近的证据表明，诸如叶绿素和类胡萝卜素等光学可测量的光合色素对水分胁迫（WS）有响应。然而，缺乏使用成像光谱学的测量，并且光化学反射指数（PRI）捕获的与叶黄素相关的反射率变化和红边位置（REP）的叶绿素变化与水分胁迫之间的联系机制尚不清楚。为了探究这一点，我们进行了一项温室实验，对3年生的苏格兰松树苗进行水分限制，并使用高光谱成像（HSI）光谱、水分状况和光合测量进行跟踪。类胡萝卜素（如叶黄素循环）和叶绿素对水分胁迫有响应，分别使用HSI衍生指数PRI和REP观察到这一点。这两种色素 - 反射率分组的时空响应有所不同。PRI的空间分布代表测量时的光照强度，而REP反映了实验过程中的日平均光照强度。在重新浇水时还注意到了另一个差异，与类胡萝卜素相关的PRI部分恢复，但与叶绿素相关的REP没有恢复。
