The increase of artificial light at night has a terrible impact on organisms with nightlife patterns such as a migration, nutrition, reproduction and collective interaction. Plants are not free from this issue as they have life cycle events occurring not only yearly but also daily. Such events relate to daytime variations with seasons in which the flowers of deciduous trees bloom and the leaves of certain trees fall off and change color. A response of plants to artificial light at night still remains poorly quantified; but recent scientific research suggest that skyglow can disturb plants processes. For instance, low levels of light affect deciduous plants, which shed their leaves as days grow short in the fall. In this paper we model skyglow considering the features of artificial light that can affect natural processes of plants during the night. A case-study was conducted to mimic skyglow effects in real location for which experimental data exist. In our numerical simulations we found that some lighting systems can have an effect on plant photoreceptors and affect the phenology of plants. Specifically, the lamps that emit the electromagnetic energy in a wide spectral range can have greater effect on the photosensitivity of the plants. We believe the results obtained here will motivate botanists to make a targeted experiment to verify or challenge our findings. If the night light can change plant behavior under some conditions, it can have significant implications in botany, biology, or even agriculture.
夜间人工光的增加对具有夜间活动模式的生物（如迁徙、营养、繁殖和集体互动）产生了可怕的影响。植物也不能免受这个问题的影响，因为它们的生命周期事件不仅每年发生，而且每天都在发生。这些事件与季节性的日间变化有关，落叶树的花朵在这个季节开放，某些树木的叶子脱落并变色。植物对夜间人工光的反应仍然没有得到充分的量化；但最近的科学研究表明，天空辉光可能会干扰植物的过程。例如，低水平的光线会影响落叶植物，当秋天白天变短时，它们会落叶。在本文中，我们考虑了可能影响夜间植物自然过程的人工光的特征来模拟天空辉光。进行了一项案例研究，以模拟实际存在实验数据的地点的天空辉光效应。在我们的数值模拟中，我们发现一些照明系统可能会对植物的光感受器产生影响，并影响植物的物候。具体来说，发射宽光谱范围内电磁能的灯可能会对植物的感光性产生更大的影响。我们相信，这里获得的结果将激励植物学家进行有针对性的实验，以验证或挑战我们的发现。如果夜间光线在某些条件下可以改变植物的行为，那么它可能会对植物学、生物学甚至农业产生重大影响。
