Title: Interannual variations in needle and sapwood traits of Pinus edulis branches under an experimental drought

Abstract

In recent years, widespread forest mortality in response to drought has been documented worldwide (Allen, Breshears & McDowell 2015). An example of widespread and rapid increase in drought-induced mortality, or die-off, was observed for Pinus edulis Engelm. across the Southwestern USA in response to several years of reduced rainfall and high vapor pressure deficits (VPD) (Breshears et al. 2009; Allen et al. 2010; Williams et al. 2013). Although stomatal closure under drought has been hypothesized to increase mortality through carbon starvation (McDowell et al. 2008; Breshears et al. 2009), more evidences exist for mortality being caused by hydraulic failure (Plaut et al. 2012; McDowell et al. 2013; Sevanto et al. 2014; Garcia-Forner et al. 2016). Regardless of the mechanism of drought-induced decline, maintaining a positive supply of water to the foliage is critical for tree functioning and survival.

  • In recent years, widespread forest mortality in response to drought has been documented worldwide (Allen, Breshears & McDowell 2015). An example of widespread and rapid increase in drought-induced mortality, or die-off, was observed for Pinus edulis Engelm. across the Southwestern USA in response to several years of reduced rainfall and high vapor pressure deficits (VPD) (Breshears et al. 2009; Allen et al. 2010; Williams et al. 2013). Although stomatal closure under drought has been hypothesized to increase mortality through carbon starvation (McDowell et al. 2008; Breshears et al. 2009), more evidences exist for mortality being caused by hydraulic failure (Plautmore » et al. 2012; McDowell et al. 2013; Sevanto et al. 2014; Garcia-Forner et al. 2016). Regardless of the mechanism of drought-induced decline, maintaining a positive supply of water to the foliage is critical for tree functioning and survival.« less
  • Studies were conducted at five Appalchian sites to determine if chemical element concentrations in sapwood tree rings from six tree species varied with soil and soil leachate acidity. The most recent 5-yr-growth increment was extracted from 10 tree boles of each species at each site and analyzed for chemical content using plasma emission spectroscopy. Sapwood tree rings generally showed higher concentrations of Mn and lower concentrations of Sr at sites with lower soil pH. Differences in tree-ring concentrations for Ca and Mn among sites were also found in soil water samples at these sites. Significant differences in soil leachate Almore » between sites were not duplicated in tree rings. Sapwood tree-ring chemistry in red oak (Quercus rubra L.), black cherry (Prunus serotina Ehrh.), eastern white pine (pinus strobus L.) and eastern hemlock (Tsuga canadensis (L.) Carr.) was generally responsive to differences in soil chemistry between sites. Chestnut oak (Quercus prinus L.) and pignut hickory (Carya glabra (Mill.) Sweet) were the least responsive species tested. Overall, results show that several common tree species and selected elements are potentially useful for studying historic soil acidification trends at these study sites.« less
  • Ponderosa and Jeffrey pine sapwood samples and freshly cut stumps from trees with different amounts of oxidant injury were inoculated with Fomes annosus. With stumps, percentage of surface cross-section area infected and extent of vertical colonization were determined 1 mo and 6-10 mo after inoculation, respectively. Increase in surface area infection with increased oxidant injury, expressed as upper-crown needle retention, was statistically significant for ponderosa pine (P=0.01), but was not for Jeffrey pine. Also, the rate of vertical colonization was greater in stumps from severely oxidant-injured trees than in those from slightly injured trees. The relationship between injury and colonizationmore » was significant for Jeffrey pine (P = 0.05) and for ponderosa pine at one site (P = 0.03), but nonsignificant (P = 0.18) for ponderosa pine at a second site. Increased susceptibility of stumps to F. annosus appeared to be associated with decreased colonization by other fungi (especially Trichoderma spp. and blue stain fungi). Laboratory tests indicated that decay susceptibility of excised sapwood to F. annosus apparently was not affected by oxidant injury with Jeffrey pine, but weight loss of ponderosa pine sapwood was correlated with decreased injury (greater needle retention). On the other hand, weight losses of Jeffrey pine caused by Polyporus versicolor and of ponderosa pine caused by Poria monticola were correlated with increased injury (increased needle chlorosis). 27 references, 2 figures, 3 tables.« less
