Abstract

The calculation of the shoot Silhouette area to Total needle Area Ratio (STAR) provides a method for assessing the light interception efficiency of a coniferous shoot. We illustrate the effectiveness of a close-range, blue light 3D scanning system as a new, affordable, and highly efficient technique for estimating STAR values. The distributions of STAR and contour length of shoots for most of the diverse species studied here are similar to those of a recently proposed optical model of a Norway spruce (Picea abies) shoot (Kuusk, A., Borysenko, O., Pisek, J., 2023. Optical model of a conifer shoot. Journal of Quantitative Spectroscopy and Radiative Transfer 310, 108,715). This implies that the conclusions, regarding the radiation scattering in a shoot can be more widely applicable and extended to the species with longer and curved, twisted needles as well.

嫩枝轮廓面积与针叶总面积比 (STAR) 和轮廓长度之间的关系

计算针叶树嫩枝轮廓面积与针叶总面积之比（STAR）是评估针叶树嫩枝截光效率的一种方法。我们展示了近距离蓝光三维扫描系统作为一种新型、经济、高效的 STAR 值估算技术的有效性。本文研究的大多数不同物种的STAR值和嫩枝轮廓长度的分布与最近提出的挪威云杉（Picea abies）嫩枝光学模型（Kuusk, A., Borysenko, O., Pisek, J., 2023.针叶树嫩枝的光学模型。定量光谱学和辐射传递杂志》310, 108,715）。这意味着有关嫩枝辐射散射的结论可以更广泛地适用于针叶较长、弯曲、扭曲的树种。
