Book excerpt: Effects of root and shoot genotypes on productivity and physiology of loblolly pine (Pinus taeda) seedlings were evaluated in contrasting nutrient regimes. Twelve-week-old seedlings from contrasting provenances were grafted reciprocally to facilitate distinction of rootstock and scion effects. Five open-pollinated families each from a mesic region (Atlantic Coastal Plain) and from a xeric region (Lost Pines Texas) were planted in a split-plot design on a nutrient-poor site in the Sandhills region of central North Carolina. A total of 1800 seedlings were used, including non-grafted trees as controls. Half of the plots were fertilized annually, and after one and two growing seasons, seedlings were harvested for component biomass determinations. Total biomass production among families was positively related to proportional biomass allocation to roots. Generally, mesic sources produced more total biomass and allocated proportionally more biomass to roots. When fertilized, mesic rootstocks were always associated with greater mass in aboveground components, regardless of scion genotype. Rootstock affected stem growth efficiency, in that xeric rootstocks were associated with increased proportional allocation to stem, regardless of scion type. Effects of root system genotype on leaf gas exchange of selected families were evaluated and related to tree growth. In two families from each provenance, light-saturated net photosynthesis (An) and stomatal conductance (gs) were measured monthly during the second growing season. Leaf carbon isotope discrimination (C13) was analyzed to estimate water use efficiency (WUE) of genotypes. Provenances differed in stomatal conductance (gs) but not in photosynthesis (An), averaged over all months. The mesic sources had lower gs and higher intrinsic WUE (An/gs). Rootstocks affected gs and leaf C13 but not An nor WUEi of scions. Leaf tissue C13 was inversely associated with stem growth efficiency and with root biomass among families, but was u.

This book was released on 2020 with total page 109 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bareroot and containerized loblolly pine (Pinus taeda L.) were planted in December 2016 and February 2017 to compare performance across four sites in South Carolina and Georgia. Main treatments analyzed for growth differences were stocktype, genetics, and planting date. Analysis of variance results showed significant growth differences after two growing seasons for containerized over bareroot seedlings, for control-pollinated seedlings over open-pollinated and varietal seedlings, and for December-planted seedlings over February-planted seedlings. Control–pollinated seedlings demonstrated the most incremental growth between ages one and two. Site conditions dictated seedling survival to a certain degree, and bareroot seedling growth was slightly better than containerized on the least stressful site. Results uncover important trends for main effects of stocktype, genetics, and planting date, but also underscore the importance for land managers to avoid blanket reforestation prescriptions, with more emphasis placed on site-specific conditions.
Book Synopsis A Physiological and Morphological Analysis of the Effects of Nitrogen Supply on the Relative Growth Rates of Nine Loblolly Pine (Pinus Taeda L.) Clones by : Corey Michael Stover
Download or read book A Physiological and Morphological Analysis of the Effects of Nitrogen Supply on the Relative Growth Rates of Nine Loblolly Pine (Pinus Taeda L.) Clones written by Corey Michael Stover and published by . This book was released on 2006 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The influence of nitrogen supply on relationships of relative growth rate (RGR) to leaf physiology, structural and non-structural carbon partitioning, and nitrogen- and water-use efficiencies were examined in loblolly pine (Pinus taeda L.) clonal lines differing in growth potential. Nine 18-month-old loblolly pine clones were grown in a climate-controlled greenhouse for 20 weeks under two contrasting nitrogen (N) regimes (50 and 250 ppm) and a growth analysis was carried out. Higher nitrogen increased plant RGR and largely resulted in proportional shifts in biomass from roots and stems to needles. The RGR of plants receiving higher nitrogen was increased primarily through increased leaf area ratio (LAR), which was increased through higher leaf mass fraction (LMF) and not through changes in needle morphology. Although concentrations of needle glucose in plants receiving 250 ppm N were 22 percent higher than plants receiving lower N, total non-structural carbohydrate concentrations in needles of plants receiving 50 ppm N were nearly double that of clones receiving 250 pm N, primarily due to starch accumulation of the nitrogen-deficient plants. Plants receiving 250 ppm N also had 39 and 18 percent lower starch in the coarse and fine roots, respectively. Plants receiving higher nitrogen were also more water-use efficient, but had lower photosynthetic nitrogen-use efficiency. LAR, net assimilation rate (NAR), specific leaf area (SLA), and LMF were all positively correlated with RGR, but the main influence on RGR differences among clones was LAR. In addition, leaf-level rates of photosynthesis and respiration were positively correlated with RGR; however, faster-growing clones did not exhibit greater carbon economy at the leaf level. Both instantaneous water-use efficiency (A/E) and [Delta]13C were positively correlated with RGR and photosynthetic nitrogen-use efficiency was negatively correlated with RGR. The identification of physiological and morphological traits underpinning differences in RGR among clones and how these traits are affected by nitrogen supply provides new information on trait correlations within species and parallels broader patterns observed among species.
