concentration in young loblolly pine trees
We measured diel patterns of stem surface CO 2 efflux ( E s , m mol m 2 s 1 ), sap velocity ( v s , mm s 1 ) and xylem CO 2 concetration ([CO 2 ]) ( X s , %) in 8-year-old loblolly pine trees during the spring to determine how v s and X s influence E s . All trees showed a strong diel hysteresis between E s and stem temperature, where at a given temperature, E s was lower during the day than at...
متن کاملMesostructure Elastic Properties in Loblolly Pine
An obvious visual feature of wood structure in many coniferous species, and especially pines, is the presence of annual growth rings. The growth rings are not completely uniform in width and often provide a record of weather and climate-based events that had an impact on growth. These events have impacts on the formation of the tapered cylindrical layer of earlywood in the early part of the gro...
متن کاملMapping Fusiform Rust Resistance Genes within a Complex Mating Design of Loblolly Pine
Fusiform rust resistance can involve gene-for-gene interactions where resistance (Fr) genes in the host interact with corresponding avirulence genes in the pathogen, Cronartium quercuum f.sp. fusiforme (Cqf). Here, we identify trees with Fr genes in a loblolly pine population derived from a complex mating design challenged with two Cqf inocula (one gall and 10 gall mixtures). We used single nuc...
متن کاملLoblolly Pine
In tests with Pinus taeda L., most properties of wet. formed hardboard were improved by using fiber refined from wood having short, slender tracheids with thin walls. A theoretical analysIs suggested that the fibers fail in bending while under stress induced by the pressing operation. Such bending failures improve conditions for hydrogen bonding, thus improving board properties. Trachelds havmg...
متن کاملIntegrating 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...
