Leaf area Index measurements for Pinus brutia Ten. Plantations in Northern Iraqi [PDF]
The surface area of the leaves of trees that perform photosynthesis is expressed by the leaf area index (LAI) for pine trees with different densities, using direct methods by collecting field data in 2022 from (30) samples, and measurements were taken of

Regional‐Scale Relationships of Leaf Area Index to Specific Leaf Area and Leaf Nitrogen Content
Specific leaf area (SLA) is an important link between vegetation water and carbon cycles because it describes the allocation of leaf biomass per unit of leaf area. Several studies in many vegetation types have shown that canopy SLA is closely related to canopy leaf nitrogen (N) content and photosynthetic capacity.

Sapwood area leaf area relationships for coast redwood [PDF]
Coast redwood (Sequoia sempervirens (D. Don) Endl.) trees in different canopy strata and crown positions were sampled to develop relationships between sapwood cross-sectional area and projected leaf area. Sampling occurred during the summers of 2000 and 2001 and covered tree heights ranging from 7.7 to 45.2 m and diameters at breast height ranging ...
