摘要

光谱反射率遥感是精准农业中的一个关键参数。特别是，由反射光产生的视觉颜色可以用于确定植物健康状况（VIS-IR）或吸引传粉昆虫（近紫外线）。然而，紫外线光谱反射率研究主要集中在非作物植物上，尽管它们为植物与传粉昆虫的相互作用提供了重要信息。这篇文献综述概述了作物的紫外线反射率，确定了文献中的空白，并提供了基于草莓品种的新数据。该研究发现，大多数作物光谱反射率研究都依赖于基于实验室的方法，并检查了较宽的光谱范围（近紫外到红外）。此外，植物家族的分布在很大程度上反映了全球食品市场的趋势。通过对白色开花草莓品种的光谱比较，本研究发现了近紫外线和蓝色范围内传粉昆虫的视觉差异。草莓品种中传粉昆虫能见度的变化突出了在开发新的作物育种系和管理农田中传粉昆虫偏好时考虑紫外线光谱反射率的重要性。

UV reflectance in crop remote sensing: Assessing the current state of knowledge and extending research with strawberry cultivars.

Abstract

Remote sensing of spectral reflectance is a crucial parameter in precision agriculture. In particular, the visual color produced from reflected light can be used to determine plant health (VIS-IR) or attract pollinators (Near-UV). However, the UV spectral reflectance studies largely focus on non-crop plants, even though they provide essential information for plant-pollinator interactions. This literature review presents an overview of UV-reflectance in crops, identifies gaps in the literature, and contributes new data based on strawberry cultivars. The study found that most crop spectral reflectance studies relied on lab-based methodologies and examined a wide spectral range (Near UV to IR). Moreover, the plant family distribution largely mirrored global food market trends. Through a spectral comparison of white flowering strawberry cultivars, this study discovered visual differences for pollinators in the Near UV and Blue ranges. The variation in pollinator visibility within strawberry cultivars underscores the importance of considering UV spectral reflectance when developing new crop breeding lines and managing pollinator preferences in agricultural fields.
