In recent years, hyperspectral imaging has been widely adopted in agriculture and plant phenotyping, while its application in forestry has been increasing. From that point onward, hyperspectral imaging has become a valuable tool for plant phenotyping, enabling the assessment of a broad range of plant traits. Given that seedlings of forest trees are one of the most widely used types of forest planting stock, advancements in hyperspectral technology have created new possibilities for improving seedling quality assessment. High-quality forest seedlings are important for the successful establishment of forest stands, especially after outplanting within...

Forest canopy structure is crucial for regulating light interception, carbon exchange, and water balance, making accurate estimation of leaf area index (LAI) essential for forest ecology and management. This study compared three indirect optical methods (LAI-2200 PCA, LaiPen LP 110, and digital hemispherical photography – DHP) for estimating effective leaf area index (LAIe) in young Norway spruce [Picea abies (L.) Karst.] stands. It evaluated the influence of the field of view (FOV) and seasonal timing on inter-method agreement. The research was conducted in young, even-aged Norway spruce stands at the Křivina...
