چکیده

Forest production depends on CO2 assimilation, but is rarely solely a function of leaf-level photosynthesis. Crown characteristics may affect tree growth by altering light interception and photosynthesis at canopy level. Strong light gradients are present in forest canopies, which often result in parallel changes in leaf morphology and leaf nitrogen for efficient use of light in photosynthetic CO2 uptake. However, the genetic basis of crown and canopy trait differences among southern pine taxa are not well understood, but critical in predicting growth and productivity differences for managing sustainable forest ecosystems.

Integration of Crown Morphology and Leaf-level Physiology as a Tool for Predicting Differences in Aboveground Productivity Among Elite Families of Loblolly and Slash Pine

Current silvicultural systems increasingly involve the deployment of genetically improved planting material, together with high-input silvicultural treatments to enhance forest productivity. As forest plantations become increasingly uniform, factors that limit tree growth should be identified in order to effectively alleviate those limitations. To this end, an important task is the identificati...

Clonal variation in crown structure, absorbed photosynthetically active radiation and growth of loblolly pine and slash pine.

Crown structure, absorbed photosynthetically active radiation (APAR) and growth were analyzed in 300 replicated loblolly (Pinus taeda L.) and slash pine (Pinus elliottii Engelm. var. elliotti) clones to: (1) quantify genetic variation in crown structural traits, growth and APAR at the species, family and clonal levels; and (2) estimate within-family genetic and environmental influences on measu...

Integrating within-crown variation in net photosynthesis in loblolly and slash pine families.

We examined photosynthetic characteristics of two fast- and two slow-growing half-sib families of both loblolly pine (Pinus taeda L.) and slash pine (Pinus elliottii var. elliottii Engelm.) on two sites in northern Florida to: (1) quantify variation in light-saturated net photosynthesis (Amax) associated with vertical crown position and foliage age; (2) quantify the amount and distribution of l...

Family Differences in Aboveground Biomass Allocation in Loblolly Pine

The proportion of tree growth allocated to stemwood is an important economic component of growth efficiency. Differences in growth efficiency between species, or between families within species, may therefore be related to how growth is proportionally allocated between the stem and other aboveground biomass components. This study examines genetically related differences in aboveground biomass a...

Aluminum sensitivity of loblolly pine and slash pine seedlings grown in solution culture.

To probe variation in Al sensitivity of two co-occurring pine species, seedlings from six full-sib families of loblolly pine (Pinus taeda L.) and slash pine (Pinus elliottii Engelm.) were grown in solution culture containing 4.4 mM (high-Al) or 0.01 mM (low-Al) AlCl(3) at pH 4 for 58 days. On average, both pine species had 41% less total dry weight in the high-Al treatment than in the low-Al tr...
