Biggest Trees of the World Pub 13-2
Dendrology Series WSFNR13-2 January 2013 Tallest, Biggest, & Oldest Trees by Dr. Kim D. Coder, Professor of Tree Biology & Health Care Warnell School of Forestry & Natural Resources, University of Georgia Trees have a long relationship with people. They are both utility and amenity. Trees can evoke awe, mysticism, and reverence. Trees represent great public and private values. Trees most noticed and celebrated by people and communities are the one-tenth of one-percent of trees which approach the limits of their maximum size, reach, extent, and age. These singular, historical, culturally significant, and massive trees become symbols and icons of life on Earth, and our role in environmental stewardship and sustainability. What Is A Tree? Figure 1 is a conglomeration of definitions and concepts about trees from legal and word defini- tions in North America. For example, 20 percent of all definitions specifically state a tree is a plant. Concentrated in 63% of all descriptors for trees are four terms: plant, woody, single stem, and tall. If broad stem diameter, branching, and perennial growth habit concepts are added, 87% of all the descrip- tors are represented. At its most basic level, defining a tree is not species based, but is a structural definition. A tree is represented by a type of plant architecture recognizable by non-technical people. The most basic con- cepts for defining a tree are -- a large, tall, woody, perennial plant with a single, unbranched, erect, self- supporting stem holding an elevated and distinct crown of branches greater than 10 feet in height and greater than 3 inches in diameter. -

IAWA Journal, Vol. 28 (2), 2007: 125-137 WOOD ULTRASTRUCTURE OF ANCIENT BURIED LOGS OF FITZROYA CUPRESSOlDES Maria A. Castro1 and Fidel A. Roig2 SUMMARY The anatomy and ultrastructure of subfossil wood of Fitzroya cup res soides from the late Pleistocene (>50,000 14C years before present) were compared with those of extant F. cupressoides trees from southern Chile, using light microscopy (polarized light and ftuorescence), scanning elec tron microscopy coupled with an energy dispersive X-ray spectroscopy system, and transmission electron microscopy. The ancient wood showed an unchanged gross wood structure, loss of cell wall birefringence, loss of lignin autoftuorescence, and a loss of the original microfibrillar pat tern. The energy dispersive X-ray spectroscopy analysis indicated higher than normal contents of S, Cl, and Na in subfossil wood. Ultrastructural modifications in the cell wall of the subfossil wood could have important implications for further studies involving isotopic and wood anatomical measurements of ancient wood. Key words: Fitzroya cupressoides, Pleistocene subfossil wood, cell wall ultrastructure, TEM, SEM-EDXA analysis, wood anatomy. INTRODUCTION The temperate rain forest of South America has a very rich tree species assemblage with a high level of endemism (Arroyo et al. 1993). One of the natural endemies is Fitzroya cupressoides (Molina) I.M.lohnston (alerce, Cupressaceae), a tree species that grows under a relatively low annual mean temperature and high precipitation in areas ofthe southernAndes ofChile and southwesternArgentina. Tree-ring analysis revealed that Fitzroya is a slow-growing tree and is one of the longest-lived tree species in the world, known to reach up to around 3,500 years of age (Lara & Villalba 1993). -

Methods for Measuring Frost Tolerance of Conifers: a Systematic Map
Review Methods for Measuring Frost Tolerance of Conifers: A Systematic Map Anastasia-Ainhoa Atucha Zamkova *, Katherine A. Steele and Andrew R. Smith School of Natural Sciences, Bangor University, Bangor LL57 2UW, Gwynedd, UK; [email protected] (K.A.S.); [email protected] (A.R.S.) * Correspondence: [email protected] Abstract: Frost tolerance is the ability of plants to withstand freezing temperatures without unrecov- erable damage. Measuring frost tolerance involves various steps, each of which will vary depending on the objectives of the study. This systematic map takes an overall view of the literature that uses frost tolerance measuring techniques in gymnosperms, focusing mainly on conifers. Many different techniques have been used for testing, and there has been little change in methodology since 2000. The gold standard remains the field observation study, which, due to its cost, is frequently substituted by other techniques. Closed enclosure freezing tests (all non-field freezing tests) are done using various types of equipment for inducing artificial freezing. An examination of the literature indicates that several factors have to be controlled in order to measure frost tolerance in a manner similar to observation in a field study. Equipment that allows controlling the freezing rate, frost exposure time and thawing rate would obtain results closer to field studies. Other important factors in study design are the number of test temperatures used, the range of temperatures selected and the decrements between the temperatures, which should be selected based on expected frost tolerance of the tissue and species.

Baum 4 Department of Botany, University of Wisconsin, Madison, 430 Lincoln Dr., Madison WI 53706 5 SUMMARY 6 • Whereas polyploidy is common and an important evolutionary factor in most land 7 plant lineages it is a real rarity in gymnosperms. Coast redwood (Sequoia 8 sempervirens) is the only hexaploid conifer and one of just two naturally 9 polyploid conifer species. Numerous hypotheses about the mechanism of 10 polyploidy in Sequoia and parental genome donors have been proffered over the 11 years, primarily based on morphological and cytological data, but it remains 12 unclear how Sequoia became polyploid and why this lineage overcame an 13 apparent gymnosperm barrier to whole-genome duplication (WGD). 14 • We sequenced transcriptomes and used phylogenetic inference, Bayesian 15 concordance analysis, and paralog age distributions to resolve relationships 16 among gene copies in hexaploid coast redwood and its close relatives. 17 • Our data show that hexaploidy in the coast redwood lineage is best explained by 18 autopolyploidy or, if there was allopolyploidy, this was restricted to within the 19 Californian redwood clade. We found that duplicate genes have more similar 20 sequences than would be expected given evidence from fossil guard cell size 21 which suggest that polyploidy dates to the Eocene.
