Some Native Hill Country Trees Other Than Oaks
Some Native Hill Country Trees Other Than Oaks Several weeks ago I wrote about the Hill Country oaks in this column. There are, however a number of common, large, native trees that are not oaks. Here are some of them. Bald cypress ( Taxodium distichum ) is common along the banks of the Guadalupe and its tributaries as well as many other streams in the Hill Country. It is unusual for a conifer (cone-bearing) tree to be deciduous (loses its leaves in the winter) which is why it is called a bald cypress. These trees were highly prized for the durability of the wood for making shingles, which led to the settlement of Kerrville. They are fast growing, and generally the largest trees in the Hill Country. Cedar elm ( Ulmus crassifolia ) is an elm with very small, stiff, rough leaves. It is common throughout the Hill Country where it appears to be equally at home on limestone soils or acidic soils. It flowers and sets seed in late summer, which is unusual, and, because not much is blooming then, it attracts many native bees when flowering. Its leaves turn yellow in the fall. Two other species of elms grow in the Hill Country, although they are not nearly as common as cedar elms. American elm ( Ulmus americana ) and Slippery elm ( Ulmus rubra ) are both large trees with large leaves and are usually found in riparian areas. Escarpment black cherry ( Prunus serotina var. eximia ) is a Hill Country native cherry with thin, soft leaves that turn yellow in the fall. The tiny white flowers are produced on stalks in the spring, followed by tiny cherries for the birds. -

On the Species Status of the Root-Knot Nematode Meloidogyne Ulmi Palmisano & Ambrogioni, 2000 (Nematoda: Meloidogynidae)

DR. GERRIT KARSSEN Thesis submitted in partial fulfilment of the degree of PLANT PROTECTION SERVICE European Master of Science WAGENINGEN in Nematology On the species status of the root–knot nematode Meloidogyne ulmi Palmisano and Ambrogioni, 2000 (Nematoda: Meloidogynidae) Mohammed AHMED 1, 2, * 1Ghent University, Department of Biology, Ledeganckstraat 35, 9000 Ghent, Belgium 2 Plant Protection Service, P.O. Box 9102, 6700 HC Wageningen, The Netherlands *Corresponding author, e–mail: [email protected] M. Ahmed Summary The root–knot nematode Meloidogyne ulmi is synonymised with Meloidogyne mali based on morphological and morphometric similarities, common hosts, as well as biochemical similarities at both protein and DNA levels. M. mali was first described in Japan on Malus prunifolia Borkh.; and M. ulmi in Italy on Ulmus chenmoui Cheng. Morphological and morphometric studies of their holo- and paratypes revealed some important similarities in certain characters as well as some general variability in some others. Host test also showed that besides the two species being able to parasitize the type hosts of the other, they share some other common hosts. Our study of the esterase and malate dehydrogenase isozyme phenotypes of some M. ulmi population gave a perfectly comparable result to that already known for M. mali. Finally, phylogenetic study of their SSU and LSU rDNA sequence data revealed that the two are not distinguishable at DNA level. -

Lacebark Elm Scientific Name: Ulmus Parvifolia Order
Common Name: Lacebark Elm Scientific Name: Ulmus parvifolia Order: Urticales Family: Ulmaceae Description The leaf arrangement of the lacebark elm (also known as Chinese elm) is alternate. Each leaf is oval with a serrate margin. Typical leaf coloration is leathery green, with purple, red, and yellow in the fall. The tree grows to a height of 40 to 50 feet with a spread of 35 to 50 feet. The bark is thin, thus giving rise to its common name as the lacebark elm. The tree produces a hard and dry fruit that brown and typically less than .5 inches in length. The root system contains a number of large-diameter members located close to the surface, and can grow for a long distance from the trunk. Growth Habit Lacebark elm is deciduous, but has been known to be evergreen in the southern extent of its range. The trees typically have a single trunk, although some have split trunks. They typically grow to a mature height of over 10 – 12 feet. It produces a bloom from late summer to fall which is yellow to green in color. A fruit is set in the fall. Hardiness Zone(s) The USDA hardiness zones for this plant are 5B through 10A. Culture Lacebark elm has no demanding culture for its habitat, and is considered to be quite hardy. It grows well in part shade as well as full sun, and has a high drought tolerance. For habitats near ocean, it has a moderate air-borne salt tolerance. For soils, it tolerates nearly all types, from clay, to sand, to loam. -

Tori were lacking in diffuse-porous species of Ampelocera, Aphananthe, Gironniera, Holoptelea, Phyllostylon, Trema and Ulmus. • Our observations suggest that tori are more common in cold temperate climates than in warm (sub)tropical environments. This may indicate that narrow tracheary elements with torus-bearing pit membranes provide an auxiliary conducting system which is of low conductivity, but offers greater resistance to freezing-induced cavitation. -

The History of Elm Breeding L
Invest Agrar: Sist Recur For (2004) 13 (1), 161-177 The history of elm breeding L. Mittempergher and A. Santini* Istituto per la Protezione delle Piante. Consiglio Nazionale delle Ricerche. Piazzale delle Cascine, 28. 50144 Firenze. Italy Abstract Breeding elms resistant to Dutch elm disease (DED) started in the Netherlands in the year 1928 on the initiative of a group of women scientists. They were active until 1954, when Hans Heybroek took over at the Dorschkamp Rese- arch Institute and carried on until his retirement in 1992. Two more programmes were initiated in Europe, in Italy and Spain, in 1978 and 1993 respectively, under the impulse of Dutch breeding activities. Elm breeding in America began in 1937 in the USDA-Agricultural Research Service Laboratories and is still being pursued under the leadership of Alden Townsend. Another programme was set up at the University of Wisconsin in 1958, led by Eugene Smalley and was closed after his retirement and death in 2002. A third programme found birth at the Morton Arboretum, Chicago, in 1972 where activities are still carried out by George Ware since his retirement. The number of resistant elm clones released on the market and the scientific progress fostered by breeding activities indicate that the long work needed to carry them on is a positive one. Among the key points considered are: elm germplasm collection, elm species cros- sability, inoculation system and disease evaluation, building up of resistance, and the possible consequences from in- troducing foreign species and hybrids to native elms. Because of shortage of funding long-term research and the per- ception that biotechnology will provide rapid solutions to long-term problems, traditional elm breeding activities seem now to be in difficulty. -
