摘要

利用高光谱反射技术追踪中国苍术光合活性变化的研究尚不充分。本研究旨在探讨土壤含水量降低对中国冬青叶片高光谱反射率与光合活性的影响。结果表明,随着土壤含水量的降低,土壤可见光和近红外波段的反射率均增加。衍生蔬菜指标光化学反射指数(PRI)和叶绿素b的色素特异性单质比(PSSRb)逐渐降低。水分指数(NWI)和水分指数(WI)的归一化差异增大。此外,PRI、PSSRb、WI和NWI与光合活性指标(即光合速率和总性能指标)呈显著相关。因此,高光谱反射是评估水分亏缺对羊草叶片光合活性影响的有效方法。

Using hyperspectral reflectance to detect changes in photosynthetic activity in Atractylodes chinensis leaves as a function of decreasing soil water content.

Application of hyperspectral reflectance technology to track changes in photosynthetic activity in Atractylodes chinensis (A. chinensis) remains underexplored. This study aimed to investigate the relationship between hyperspectral reflectance and photosynthetic activity in the leaves of A. chinensis in response to a decrease in soil water content. Results demonstrated that the reflectance in both the visible light and near-infrared bands increased in conjunction with reduced soil water content. The derived vegetable indices of photochemical reflection index (PRI) and the pigment-specific simple ratio of chlorophyll b (PSSRb) gradually decreased. In contrast, the normalized difference in water index (NWI) and water index (WI) increased. Moreover, significant correlations were observed between PRI, PSSRb, WI, and NWI and photosynthetic activity indices, namely photosynthetic rate and total performance index. Consequently, hyperspectral reflection represents a productive approach for evaluating the influence of water deficit on photosynthetic activity in A. chinensis leaves.
